Flash News: US Marines Conduct First-Ever Live-Fire Training in Hawaii with MADIS Air Defense System
The U.S. Marines conducted a live-fire training exercise with the Marine Air Defense Integrated System (MADIS) at the Pohakuloa Training Area in Hawaii on January 25, 2025. This exercise, marking the first time the MADIS was fired on a Hawaiian island since its fielding in December 2024, served to commemorate the system’s addition to the Marine Corps’ arsenal and its rigorous months of operational testing and evaluation. The training was held at the Pohakuloa Training Area, a prime location for live-fire exercises.

The MADIS (Marine Air Defense Integrated System), a ground-based air defense system designed to counter unmanned aerial systems (UAS), was tested by Marines of the 3d Low Altitude Air Defense Battalion’s (LAAB) Ground-Based Air Defense Battery. The live-fire event offered Marines an opportunity to demonstrate and refine their capability to detect, track, identify, and engage a variety of aerial threats, specifically targeting UAS in a highly contested and dynamic environment. The MADIS is capable of deploying a mix of weapons systems including missiles, air-to-air launchers, chain guns, machine guns, and simulated munitions, all integrated into a single, highly flexible platform.
The MADIS is a cutting-edge, mobile, short-range air defense system designed to address the evolving threat of drones and other low-altitude aerial platforms. Built to provide rapid-response capabilities, it enables ground forces to operate with greater autonomy and enhanced combat effectiveness, especially in scenarios where threats come from small, agile, and difficult-to-detect unmanned aerial systems (UAS).
The MADIS will consist of two distinct variants: the MADIS Mk1 and the MADIS Mk2. Each variant is designed to complement the other, providing a layered and adaptable air defense solution that meets the unique needs of the Marine Corps’ Ground-Based Air Defense (GBAD) units. The MADIS Mk1 includes a turret-launched Stinger missile, multi-functional electronic warfare (EW) capabilities, a direct fire weapon, an Electro Optical Infra-Red (EO/IR) optic, and a shoulder-fired Stinger missile for dismounted operations. This variant is designed to deliver a robust air defense solution capable of engaging targets both from a mounted position and through individual soldier operations. The turret-launched Stinger missile provides longer-range engagement against hostile aerial threats, while the shoulder-fired Stinger allows for flexibility in dismounted operations, empowering Marines with a portable anti-air defense capability.
On the other hand, the MADIS Mk2 (C-UAS variant) is optimized for counter-unmanned aerial system (C-UAS) operations, incorporating a multi-function EW capability and a 360-degree radar system for full situational awareness. The Mk2 also includes a direct fire weapon, EO/IR optics, and a supporting command and control (C2) communications suite, which facilitates seamless coordination and command across dispersed units. This variant enhances the Marines’ ability to track and neutralize UAS threats in complex environments, offering real-time intelligence and enabling integrated responses across the battlefield. The Mk1 and Mk2 form a complementary pair, and together, they represent the core of the LAAD Battalions’ GBAD capability.
The MADIS system provides a highly mobile and flexible air defense solution. Its ability to detect, track, and engage a wide range of aerial threats—especially small and low-flying UAS—gives ground forces a significant edge in modern warfare. The system’s combination of radar, EW, and direct fire capabilities allows for layered defense, addressing both kinetic and non-kinetic threats. Whether in a mounted or dismounted configuration, the MADIS allows Marine units to react quickly and effectively to emerging threats in a variety of operational scenarios.
The integration of the MADIS into Marine Corps operations is part of the broader effort to modernize and enhance air defense capabilities across the force. The system not only increases the tactical flexibility of the 3d MLR but also ensures that these Marines are equipped with the most advanced tools available to counter the growing threat posed by UAS and other low-altitude threats.
The fielding of the MADIS provides the 3d Marine Littoral Regiment with a critical enhancement to its air and missile defense capabilities. As a highly mobile and effective air defense system, it significantly extends the range in which the regiment can sense, engage, and neutralize aerial threats, particularly in the region’s vast and often remote operational theaters. This system empowers the 3d MLR to operate more independently, reducing reliance on broader joint-force support and increasing its self-sufficiency in air defense operations.
The 3d MLR, stationed on Oahu, Hawaii, and focused on amphibious and littoral warfare, is an essential unit in the Marine Corps’ strategic posture in the Indo-Pacific region. The regiment plays a crucial role in regional security, conducting operations that ensure the protection of U.S. interests and strengthen alliances with partner nations across the Pacific. The MADIS, as part of the 3d MLR’s operational toolkit, reinforces the Marine Corps’ readiness to respond to growing challenges posed by near-peer adversaries and non-state actors deploying advanced aerial systems.
In addition to its operational capabilities, the live-fire event allowed commanders and subject matter experts to engage with attendees, discussing the process of fielding the MADIS and its operational value. Training with the MADIS reflects the Marine Corps’ continued commitment to a threat-informed, concept-based approach to modernization, adapting its forces to meet emerging threats and ensure its relevance in future conflict scenarios.
As the U.S. Marine Corps continues to adapt to the changing landscape of warfare, the integration of advanced systems like the MADIS ensures that forces in the Indo-Pacific—and beyond—remain capable of meeting evolving air threats. The success of this training event underlines the operational flexibility and value of the MADIS, marking it as a cornerstone of the Marine Corps’ future force design and operational readiness in an increasingly complex and contested global security environment.
The MADIS’s integration into Marine Corps operations signals a new era of air defense capabilities, and the training at Pohakuloa serves as a testament to the dedication and innovation that continues to drive the U.S. Marine Corps’ modernization efforts. With the ongoing development of new tactics, techniques, and procedures for its use, the MADIS is poised to play an essential role in safeguarding the U.S. and its allies in the Indo-Pacific and other strategic regions.

7 Stunning Small Towns In Hawaii
Hawaii offers a wide range of small towns across its islands, each with its own draw. The state has hikes among active volcanoes near Volcano Village and long stretches of coastline like Waimanalo Beach on Oahu. One town below sits on a crescent-shaped bay that has drawn visitors for decades. Another holds a winery on volcanic slopes. The list ahead covers seven small towns spanning beach and inland Hawaii.
Hanalei
On the north shore of Kauai, the census-designated place of Hanalei is known for a laid-back atmosphere, a crescent-shaped bay, and a small collection of shops and restaurants. Hanalei Beach is a stretch of fine sand and clear water, and has been featured in films including The Descendants and South Pacific. It has been ranked among the state’s best beaches, with picnic tables, good surfing, and kayaking all within reach. Within walking distance is the Hanalei Inn, a small retro-style lodging near downtown.
Further into town is the Wai’oli Mission House, a historic two-story missionary home built in 1837 and preserved as a museum. Tours run from 9:00 a.m. to 3:00 p.m. on Tuesdays, Thursdays, and Saturdays, covering the lives of the missionaries who lived there. Near Black Pot Beach is Pat’s Taqueria, a Mexican food truck serving Hawaiian-style tacos, burritos, and quesadillas within walking distance of the Hanalei Pier. Locals and visitors both favor it for its locally sourced ingredients.
Pāʻia
In the north of Maui is Pāʻia (also spelled Paia), a walkable community with local surf shops, restaurants, and ocean views. Lower Pāʻia Park is one of the more photographed beaches in the state, with calm waters good for snorkeling, surfing, and swimming. Basketball courts, a skatepark, and a youth center sit nearby. Near the beach, the Surf Club is an event venue for weddings, dinners, and corporate or private functions, with a short walk back to downtown.
Wabisabi Soba and Sushi is a sushi restaurant on the Hana Highway known for its 100 percent buckwheat Jyuwari soba noodles. The interior and garden lean Japanese, and the restaurant is BYOB. The Rip Curl Surf Shop in downtown stocks swimwear, boardshorts, surf accessories, hats, surfboard covers, and apparel for anyone heading out to the waves.
Waimanalo
On the east side of Oahu is Waimanalo, a community with a three-mile stretch of beaches, a laid-back culture, and an agricultural character. At the eastern end of town is Sea Life Park Hawaii, an aquarium and animal sanctuary home to dolphins, sharks, sea lions, native fish, rays, and birds. Visitors can interact with animals in the water, visit penguin habitats, meet sea lions, and see sea turtles. Waimanalo Beach is a wide stretch of white sand backed by the Ko’olau Mountains, with turquoise water for swimming and surfing, and Waimanalo Beach Park shaded by ironwood trees. Parking is limited, especially on weekends and holidays, so arriving early is best.
Further inland, Olomana Golf Links is an 18-hole par-72 course with the Ko’olau Mountains in the background. Former U.S. President Barack Obama has played here, and professional golfer Michelle Wie trained on the course. The Waimanalo Forest Reserve is farther still, with quiet hikes on trails such as the ‘Ohana Trail and the Maunawili Ditch Trail, home to wild birds, small mammals, and reptiles, along with views of Maunawili Falls within the 500-acre reserve.
Volcano
Volcano, or Volcano Village, sits as the gateway to Hawai’i Volcanoes National Park in a cool, damp rainforest setting. The park is home to two active volcanoes: Kīlauea, one of the most active volcanoes in the world, and Mauna Loa, the largest shield volcano in the world. The rest of the park holds geographical features that often require multiday trips to reach. Visitors can view lava eruptions, hike, and explore the rolling hills of the Kahuku Unit.
In the heart of town, the Lava Lodge at Hale Kilauea offers cottages for visitors exploring the park. Each cottage has a small tropical garden. The hotel is within walking distance of the Lava Rock Cafe, which serves burgers, pancakes, and local Hawaiian dishes. Volcano Winery is one of only a few wineries in the state, with views of Mauna Loa and a rare chance to taste Big Island wines on the Big Island itself.
Lānaʻi City
At the center of the island of Lānaʻi is Lānaʻi City, a plantation town with historic homes, local restaurants and shops, and a walkable center. On Lanai Avenue, Dreams Come True Bed and Breakfast is a renovated property with mountain views and a garden. Further up in town, the Lānaʻi Culture and Heritage Center preserves the island’s history, traditional cultures, and plantation past through photographs and artifacts.
The Lānaʻi Art Center is within walking distance of the Culture and Heritage Center. It serves as a studio space for local artists, features a gallery, offers classes and workshops, and is the island’s main community arts program. On the outskirts of town is the Koloiki Ridge Trailhead, a roughly 5-mile trail that follows old cattle paths and opens up to panoramic views of the island.
Honokaa
On the northeastern coast of the Big Island is Honokaa, a census-designated place with plantation-era architecture and a role as gateway to Waipi’o Valley. The Honokaa Heritage Center is a museum covering the town’s history, with research materials and exhibits of photographs and artifacts. The center hosts the Hāmākua Sugar Days Festival every October, dedicated to the state’s plantation history with parades and a festival fair. South of the heritage center is the Hāmākua Country Club, a nine-hole course and one of the oldest on the island, set 1,200 feet above sea level with views of the Pacific Ocean. Carts are available for rent, and the course hosts tournaments.
Waipi’o Valley is just west of town. It was the boyhood home of King Kamehameha and is considered one of the most sacred places on the Big Island. Trails such as the Muliwai Trail lead into the tropical valley, where coconuts, green bananas, and papayas grow. Note that valley access is currently restricted to Hawaii residents.
Makawao
Upcountry from Paia is the census-designated place of Makawao, a community with boutique shops, art galleries, and an upcountry character. Makawao Public House is a gastropub serving local fare and paying tribute to the town’s past. On Baldwin Avenue, Banyan Tree Bed and Breakfast sits on 2.5 acres of gardens with cottages for stays, a short drive from local restaurants and shops.
On the southern outskirts of town is the Kahakapao Loop Trail, a 5.9-mile route in the Makawao Forest Reserve that is a popular hiking and mountain biking spot. At roughly 4,000 feet, the rainforest setting offers a cooler alternative to a beach day. At the northern edge of town, the Hui No’eau Visual Arts Center operates as a cultural hub with a gallery, classes, workshops, a gallery shop, and exhibits by local community members.
Small-Town Hawaii
Hawaii’s small towns provide a different side of the state from the major resorts, with local character, natural features, and regional history. Makawao draws visitors to the Makawao Forest Reserve. Volcano offers access to two of the state’s most active peaks. Waimanalo’s white-sand beach anchors the east side of Oahu. Each of these communities offers something different from the others, but all share a strong sense of place.

Hawaii Snorkel Tour Hits Rough Waters After Tourtist Allegedly Stabs Boat Captain | Oxygen
A Kansas man is accused of stabbing a Hawaii boat captain at sea with a filet knife.
Avery Nissen is now facing charges of second-degree attempted murder in connection to the April 16 attack, which took place during a three-hour snorkel tour off the Kona coast, according to a statement from the Hawai’i Police Department.
When Kona patrol officers arrived at the Honokōhau Harbor, they found the captain of the boat—identified as Stanley Lurbiekci, according to Hawaii News Now—suffering from stab wounds to the lower abdomen and cuts to the head and hands.
Witnesses aboard the boat told police that Nissen allegedly attacked the captain with a filet knife. Other passengers intervened and restrained him until the boat made it back to shore.
The 62-year-old was transported to the Kona Community Hospital, where police said he remains in stable condition.
Owner and president of Hawaii Nautical Mark Towill described Lurbiekci as a “real hero and a fighter.”
“I’m just incredibly grateful that our team is safe and that the situation ended the way it did,” Towill told the news outlet. “I’ve never heard of anything like this happening in this industry before, and just really grateful to all of our team for the way that they reacted, the professionalism that was demonstrated.”
Police said the motive in the attack is unknown.
In addition to the second-degree attempted murder charge, prosecutors have also charged Nissen with first-degree assault and second-degree assault, police said.

A Deep Dive into Hawai‘i’s Shell Jewelry Industry – Hawaii Business Magazine
They adorn casual beachgoers, become treasured accessories for bridal parties and decorate the resplendent elite as they glide among guests at private dinners.
Hawaiʻi is a rich resource for this nascent business sector as demand builds across the Islands and across the globe. Exactly how big a business it has become is something of a mystery, though. State figures actually show the number of licensed sellers has declined in recent years, though officials admit that’s probably due to lack of awareness and noncompliance rather than reflecting reality.
“Shell jewelry has really only exploded in the last seven or eight years,” says Brooke Holt, founder and designer of 21 Degrees North Designs on Oʻahu. “Don’t get me wrong,” she adds, “I love shells. I love shell jewelry. That’s why I first wanted to make it, [but] I’m kind of over it at this point because it’s so oversaturated.”
When Holt started making shell jewelry in the mid-1990s, there weren’t many others creating newer styles of jewelry with Hawaiian shells outside of the revered tradition of Niʻihau shell lei. Now, jewelers selling shell designs are abundant, judging by the availability of choices online and in stores. Accessories such as sunrise shell necklaces, Hebrew cone earrings, and miter and Tahitian pearl bangles have become iconic staples of island style.
While the shell jewelry industry appears to be expanding in tandem with the popularity of this merchandise, it remains a largely under-documented domain, lacking the data necessary to quantify its true size and impact. Strict requirements of state regulations may actually be driving sellers to evade the mandates.
Technically, anyone taking marine life from Hawaiian waters for commercial purposes must hold a Commercial Marine License (CML), according to the state Department of Land and Natural Resources’ Division of Aquatic Resources (DAR). The license, which costs $100 for residents and $250 for non-residents annually, mandates strict monthly harvest reporting.
“It is important to note that because marine life is defined in the rule as including even parts of living organisms, this licensing requirement applies to the commercial collection of live specimens, empty shells, and even shell pieces,” says DAR Aquatic Biologist Bryan Ishida.
Regulation extends down the supply chain. Businesses that purchase marine life — including empty or fragmented shells — directly from CML licensees for commercial resale must obtain a Commercial Marine Dealer License (CMDL), which costs $100 per year and requires weekly reporting.
Ishida says these licensing fees “are vital to maintaining DAR’s objective of protecting aquatic resources for future generations.” By law, these proceeds are directed into the Commercial Fisheries Special Fund to bankroll research, monitoring and the staff that work in commercial fisheries management.
These reports also serve as an economic barometer. “CMDL reports, in particular, provide the ability to track even small changes to market demand, pricing and other trends,” Ishida explains.
However, the department admits licensing and reporting compliance in the shell sector is “likely quite low” compared to the seafood sector. According to their records, commercial participation peaked in 1977 with 44 shell collectors submitting reports; over the last decade, the number of CML holders reporting shell harvests has dwindled to ten or fewer annually.
This decline is primarily attributed to a lack of awareness. “DAR recognizes this and understands that increased outreach and non-enforcement measures are needed to raise compliance,” Ishida says, but the agency must prioritize using “their limited resources on the harvest of live aquatic life,” and most shells harvested for jewelry are thought to be empty shells.

Honoring a Tradition
Shell jewelry has been an integral part of Hawaiian culture for centuries, with ample evidence indicating Niʻihau shell lei predate the arrival of Captain Cook in 1778. They are made of rare, tiny shells found off the rugged coast of the Forbidden Isle.
According to Kealoha Figaroa, founder of Niʻihau shell jewelry company Pūpū Creations, many of the shell species used to construct Niʻihau shell lei are found on other islands, but ones found on Niʻihau are prized because they “hold their luster” better. He guesses that this is because there’s comparatively less freshwater runoff into the ocean. “My family tells me on Niʻihau, the water is so pristine that you can see about 300 feet down into the bottom of the ocean,” he says. For his family, and many others from the island, the tradition of creating shell leis has been passed on for many generations.
Figaroa recalls memories from childhood spent at a table where elders would dump hundreds of shells for the children to organize. “All our grandparents… they would take all the kids, and they would tell us, ‘Okay, you need to sit here and sort these shells by color, by size, by all that.’ And of course, we hated it. But for the older people, it was very important for us to learn these things, so that when we do see these leis, we have much more appreciation for the leis.”
Once they had mastered the sorting process, the children would learn the delicate art of piercing the shells. Only after proving their proficiency in that skill were they allowed to begin stringing them together, starting with smaller pieces like earrings before eventually advancing to leis.
Still, Figaroa says that gathering shells from the beach is by far the most tedious part of the process. Figaroa explains that collecting a sufficient number of matching shells to create a high-quality, symmetrical lei requires immense patience. “It’s anywhere from two weeks all the way up to three years to make one lei,” he explains. The considerable time and craftsmanship required to create these intricate pieces are reflected in their price tag, which can reach upwards of tens of thousands of dollars.
Figaroa, who lives on Oʻahu, says his cousins frequently send him shells from Niʻihau to create the lei sold by his business, Pūpū Creations. “I allow space for my family members to also have some other items on sale so they can profit from it as well, and not just myself.” He says one reason he loves collaborating with his relatives is that “there’s different family members that have specific styles.”
One of his cousins, for example, specializes in delicate color gradients. And Figaroa, mentored by his grandmother, took after her in specializing in working with momi shells to create three-strand leis and the straight Kui Pololei style.

The Evolution of Shell Jewelry
Newer styles of Hawaiian shell jewelry have emerged in recent decades. They often feature cone shells, cowries, drupes and miters not typically found in the Niʻihau shell lei tradition.
One of the contemporary style shell jewelry makers on the scene is Anoʻipua Kaaloa, who started out as a shell collecting hobbyist. Kaaloa says the kinds of shells she finds differ based on whether or not she’s looking on the Windward Side or Leeward Side: On the east side, “I’ll find a lot of abbreviated cones, tumbled pink cones, the endemic Hawaiian golden yellow cones, strombs, Adam’s miters, lettered miters. Then on the other side of the island, I find so many cowries” and rarer shells to come by, “like marble cones, leopard cones.”
She says she saw other people making jewelry with their beach finds and thought, “That looks cool. I think I can do that with my shells.” Her business, ʻAnoʻipūpū Jewelry, sells everything from shell necklaces, earrings, bangles, belly button rings and keychains. She says her favorite pieces to make are resin earrings that contain a bunch of different micro shells because they are one of her more “unique” designs.
When she started selling her pieces in late 2024, Kaaloa says she was motivated to not only create “nice jewelry, but more affordable” merchandise, because a lot of the market is “really expensive.” When figuring out her price points, she says she considered “if I was to buy my own jewelry, what prices would I want to set?”
Like many other shell jewelry businesses, Kaaloa operates without a traditional brick-and-mortar storefront. Instead, she has built a loyal following through markets, appearing as a regular vendor at the Kakaʻako Farmers Market every Saturday and the Kailua Farmers Market on Sundays.
Despite having neither a physical shop nor an e-commerce website, Kaaloa found enough success at the markets that she was able to quit her former job in the food service industry and focus on running her business full-time a little over a year into opening ʻAnoʻipūpū Jewelry. “I’m grateful, that’s for sure,” she says.
Holt, founder and designer at 21 Degrees North Designs, makes jewelry from an array of materials, including coral, pearls, sandalwood beads, neon thread, lauhala, silver, gold and, of course, shells.
Having partially grown up in Mākaha, she’s been frequenting Oʻahu’s west side beaches in search of shells since the 1980s.
“I had different beaches for different shells,” Holt explains. “Some shells you can find up and down the coast, but others you can only find in very specific spots. I started then researching what types of shells grow in what types of reef situations.”
The daughter of a fashion designer mother and a glass blower father, Holt naturally felt inclined to do something creative with the shells she found, which led her to taking up jewelry making.
Holt finds that inspiration can strike from anywhere: “sometimes it’s a color, sometimes it’s a concept, sometimes it’s a place.” For instance, the design for one of her first pair of statement earrings began with a moment of observation while surfing.
Captivated by how “the water and the sun playing on the ripples gives it all those little dancing rings, I wanted to make earrings that represent that, so I made these concentric circle earrings. I like organic shapes and asymmetrical things.”
In an era of viral trends and mimicry, Holt says it’s important that her pieces stand out. That’s “the greatest compliment I can get, and I do hear it a lot at my markets. I want to be different. I don’t want to look like anyone else.”
One concern Holt has is the impact an increase in shelling has on the environment: “You want to encourage entrepreneurship, but again, we’re still perpetuating this culture of, take, take, take…. So, yeah, do we need to start having limits?”

The Ethics of Shelling
It isn’t illegal to take live shells, but Ishida says “DAR requests that commercial collectors do so sparingly and only as demand requires as many species are quite rare” or little is known about their abundance. The agency strongly recommends collecting empty shells rather than live specimens.
“However, DAR asks commercial collectors to remember that shells, even when empty, contribute to the ecosystem, whether providing a home for a hermit crab or over years wearing down into sand and other seafloor substrate,” says Ishida.
For artisans like Figaroa, Kaaloa and Holt, the first rule of the reef is absolute: only take empty shells. They look for signs of life — like a visible body or a sealed operculum — whereas sand and rocks in the aperture indicate the shell is dead. “The only way shells can reproduce plentifully is if the reef system is healthy. If the reef is not healthy, you won’t get your shells,” Figaroa says.
Marine educator Keoki Stender, founder of MarinelifePhotography.com, warns that damage often happens through simple negligence, such as walking on reefs made of mussels and oysters at low tide: “If you trample it, you crush the shells. You kill hundreds at one time. You have to be mindful of what you’re stepping on.”
He also implores beachgoers to return things back to where they originally were when exploring the ocean and tide pools. For example, “If you leave the rock overturned, the sun’s going to fry everything [on the bottom], the fish are going to eat everything that is here and exposed, and then the life that was on the top of the rock is going to die [underneath], and the part of the reef where you turn the rock and put it onto the reef is going to kill everything on that part of the reef too,” he says.
Ishida reminds commercial collectors that as a natural resource, “empty shells are for everyone’s enjoyment. People who want to collect shells for their own personal collection, jewelry making for themselves, or just enjoying seeing them while diving should be able to do so. Accordingly, commercial collectors should think about their impact on not only the environment but others who may want to collect shells for non-commercial purposes.”

Where Shells Come From and What to Look Out For
The shells used in jewelry come from animals in the mollusk phylum. To protect their vulnerable, soft bodies, many mollusks have evolved to build exoskeletons, a.k.a. shells, by secreting minerals through a specialized organ called the mantle.
Keoki Stender, a marine educator, photographer and founder of MarinelifePhotography.com, says that you can glean a great deal about a mollusk’s lifestyle by examining its shell. Cowries, for instance, are the heavy-duty tanks of the reef. Their domed, “bottom-heavy” shell is engineered for stability. “The ones that are most domic — a humpback, very domed, flat bottom — they would be more likely to be in a high surf environment,” Stender explains. Combined with a foot that provides powerful suction, the humpback cowries’ low center of gravity allows it to “handle the full force of breaking waves” without being swept away.
In contrast, he says, the streamlined, “tapered shape” of miters and augers allows them to easily crawl through sand in search of prey. And the elaborate, spiny architecture of murexes serves as a defense “designed so no one can bite them.”
The diversity of patterns, from the distinctive black markings on Hebrew cones to the vibrant ombré of sunrise shells, is produced by pigment-secreting cells in the mantle. These cells act much like an inkjet printer, depositing color at the growing edge of the shell.
Some specimens in Stender’s extensive shell collection.
Cone snails are predators that hunt using a venomous harpoon-like tooth that shoots out the base of their shell. Their toxicity generally depends on that species’ diet. “The worm eaters are like a bee sting [to humans]. But if you’re allergic to bee sting, that can be really bad,” Stender warns. “The fish eaters are especially bad because if your prey is fast moving, you got to have a potent sting.”
Because specific cone snail species are among the most venomous animals on earth, being familiar with their patterns to discern which are dangerous is extremely important when handling. “The ones that have the worst sting are the tented pattern cones,” says Stender. In Hawaiʻi, textile, banded marble and striated cones possess a sting that is potentially fatal to humans.
Stender explains that lifespan varies significantly across species, noting a direct correlation between shell size and growth rate. “The bigger the shell, generally, the slower it grows,” he says, because the animal must extract a higher volume of minerals from both the water and its food to build its home. While Stender estimates that many micro-shell species live for only six months to a year, some larger mollusks — such as the leopard cone and tiger cowry — can live for a decade or longer.
