Colossal white shark tagged by OCEARCH, frequent Florida visitor, pings in rare location
Sharks could help predict hurricanes
Researchers at the University of Delaware and hoping that sharks equipped with sensor tags can help forecasters better predict hurricanes.
The largest male great white shark ever tagged and released by the nonprofit research group OCEARCH is making waves again, this time with a rare ping location.
The 13-foot, 9-inch, 1,653-pound shark, nicknamed Contender, was tagged in the waters off the Florida-Georgia border in January 2025.
Shortly after, Contender toured the east coast of Florida.
The massive animal first surfaced in Sunshine State waters on Jan. 26, 2025, pinging three times off the Fernandina Beach coast. Contender then zig-zagged between Amelia Island and Jacksonville Beach before swimming south to the waters off St. Augustine on Feb. 6, Volusia County on Feb. 8 and 9, and Brevard County waters on Feb. 10.
Contender then headed north, pinging off Cape Cod, Massachusetts, in July — staying “silent” (or no pings) until Sept. 29.
That’s when the shark pinged about 857 miles north, in the Gulf of St. Lawrence, northeast of Anticosta Island, Canada, a region OCEARCH-tagged sharks rarely ping from, the group’s senior data scientist John Tyminski said in an Instagram video.
“Big shark, big journey,” Tyminski said.
Tyminski said the food supply – harbor and gray seals, along with abundant schooling fish, such as mackerel and herring – is what’s most likely drawing Contender into the 50-degree waters.
Here’s what to know about Contender, OCEARCH and great white sharks:
Contender is the biggest male great white shark tagged by OCEARCH
Contender measured 13 feet, 9 inches and weighed 1,653 pounds at the time of tagging, making it the largest male white shark ever tagged by OCEARCH.
“Contender is the largest male white shark the OCEARCH team has sampled, tagged, released and studied to date in the NW Atlantic white shark population! So he’s pretty special,” Nicole Ralson, OCEARCH chief marketing officer, said in an email.
Massive great white shark caught and tagged off Florida-Georgia coast
Contender is a 1,653-pound great white shark, the largest male tagged and released by OCEARCH scientists. He was tagged off the Florida-Georgia coast.
What do we know about OCEARCH great white shark Contender, who has surfaced several times in Florida?
Contender, an adult male white shark, was tagged by OCEARCH off the Georgia-Florida coast on Jan. 17, 2025.
“Meet Contender, the ultimate ocean warrior! This powerful white shark was tagged on January 17, 2025, off the FL/GA coast, about 45 miles offshore,” the shark’s tracker page reads. “Contender is a mature male now contributing to OCEARCH’s mission of shark research and ocean conservation.”
According to his tracker, Contender has traveled 3,210 miles since being tagged.
Contender was reportedly named for Contender Boats, a longtime OCEARCH partner.
What is OCEARCH? What does research group do for great white sharks?
OCEARCH is a nonprofit research organization studying the ocean’s giants.
The group studies keystone species, including great white sharks, essential for the health of the oceans.
“At OCEARCH, we’re on a mission to solve the Global White Shark Puzzle. There are nine populations of white sharks across the globe and OCEARCH’s goal is to assist regional scientists to better understand the life of the white shark in each of these populations,” the group’s website states.
Jacksonville University has been the academic home for OCEARCH for nearly a decade and the planned new location for the group’s new headquarters facility is in Mayport, Florida.
How many great white sharks are there?
There’s no absolute data on the global population of white sharks and estimates vary widely – from 3,000 to over 10,000.
According to NOAA Fisheries:
- The stock status for white shark populations in U.S. waters is unknown and no stock assessments have been completed. No stock assessments are currently planned in the Atlantic.
- Research by NOAA Fisheries scientists indicates that abundance trends have been increasing in the northwest Atlantic since regulations protecting them were first implemented in the 1990s.
- According to a NOAA Fisheries status review and recent research, the northeastern Pacific white shark population appears to be increasing and is not at risk of becoming endangered in U.S. waters.
What do great white sharks eat?
According to NOAA Fisheries, white sharks have a diverse and opportunistic diet of fish, invertebrates and marine mammals.
Juvenile white sharks mainly eat bottom fish, smaller sharks and rays, and schooling fish and squids.
Larger white sharks often gather around seal and sea lion colonies to feed and also occasionally scavenge dead whales.
Great white sharks in Florida: Why are they here? What to know
North Atlantic great white sharks spend winters off the southeast U.S., from South Carolina to Florida and the Gulf of Mexico. Here’s why.
Great white shark facts
- Weight: Up to 4,500 pounds
- Length: About 4 feet (at birth) and up to 21 feet (adult)
- Lifespan: 70 years or more
- Threats: Bycatch, Habitat Impacts, Overfishing. According to NOAA Fisheries, the white shark is a prohibited species (no retention allowed) in all U.S. waters and fisheries. There are no commercial fisheries for white sharks, but they are occasionally caught as bycatch.
- Region: Alaska, New England/Mid-Atlantic, Pacific Islands, Southeast, West Coast
- Teeth: Great white sharks have 300 teeth but don’t chew their food. Instead, they rip it into pieces and swallow it whole. The sharks have an endless supply of teeth, with lost teeth regenerating infinitely.
- Smell: According to OCEARCH, great white sharks can sniff out a single drop of blood in an Olympic-sized swimming pool.
- Sight: Great white sharks can see well in low light, enabling them to hunt at dawn, dusk, or in deep waters, OCEARCH reported.
- Additionally, white sharks can detect weak electrical signals emitted by living creatures, even under sand. They also identify vibration changes in the water, allowing them to find prey by sensing movement.
OCEARCH shark tracker: Follow great white sharks in Florida, beyond
North Atlantic great white sharks migrate as far south as Florida and the Gulf in winter, searching for warmer waters and more food sources.
According to the group’s website, OCEARCH is “a global nonprofit organization conducting unprecedented research on our oceans’ giants in order to help scientists collect previously unattainable data in the ocean.”
OCEARCH has tagged 140 white sharks, many of them along the Eastern Seaboard and Nova Scotia.
You can follow their journeys on the OCEARCH shark tracker website or by downloading the OCEARCH Global Shark Tracker app.

Audubon Florida leader has built reputation for working across party lines | The Invading Sea
By Issabella Gutierrez
As a child growing up in rural Florida, Julie Wraithmell once stood at the foot of a tall pine tree and watched a woman climb 50 feet into the air to occupy an abandoned eagle’s nest. The woman, Doris Mager, stayed there for a week to raise money for raptor rehabilitation. For young Julie, the “nest-in” became a blueprint for a life in conservation.
In Florida’s often unpredictable environmental policy landscape, Wraithmell has built a reputation for working across party lines.
Today, as the vice president and executive director of Audubon Florida, the state office of the National Audubon Society, she leads the organization’s statewide science and advocacy efforts from her office in Tallahassee. She spends the legislative session in committee hearings and meetings with lawmakers, agency officials and conservation leaders.
Over two decades, she has evolved from a field biologist and self-described “bird nerd” into an influential environmental leader in Florida, navigating a political landscape that can be as unpredictable as any treetop.
A native Floridian, Wraithmell earned a bachelor’s degree in biology from Duke University and a master’s degree in science from Florida State University.
She began her career in 1997 as a biologist at the Florida Fish and Wildlife Conservation Commission, where she worked for eight years and helped launch the Great Florida Birding Trail, a 2,000-mile network connecting more than 500 wildlife-viewing sites.
Wraithmell now oversees 80 Audubon Florida staff members and 45 chapters statewide. Beyond lobbying, she directs habitat restoration strategies and coordinates policy teams focused on land conservation and water quality.
Renée Wilson, a senior communications coordinator at Audubon Florida, described Wraithmell as a “getter-donner” who remains “cool as a cucumber” even when tension runs high in the Capitol.
“She’s not a micromanager,” Wilson said. “She gives you the direction you need, and she’s there if you need a course correction, but she really empowers the staff to follow their passions.”

Her leadership was tested in 2024 and 2025, when proposals surfaced to add golf courses to state parks and to swap protected land at the Guana River Wildlife Management Area for development. Audubon Florida helped generate tens of thousands of public comments and coordinated bipartisan opposition that led to the withdrawal of both proposals.
Elizabeth Alvi, senior director of policy for Audubon Florida, said Wraithmell’s leadership in these sensitive moments is defined by a refusal to be pulled off course by short-term pressure. She added that Wraithmell is widely respected by lawmakers across the aisle.
“People know that when she speaks, it is grounded in science and aligned with a clear organizational priority, not opportunistic positioning,” Alvi said. “That discipline earns respect in the Capitol because it’s consistent and thoughtful.”
Wraithmell often quotes a mentor who told her that advocacy requires “weaving back and forth across the political aisle like sloppy drunks.”
“You might find yourself fighting a legislator over a road project one year, but you have to be ready to partner with that same person on a land conservation bill the next,” Wraithmell said. Holding onto professional grudges, she said, is a luxury the environment cannot afford.
That pragmatism shapes her push for stable funding for Florida Forever, the state’s land acquisition program that has preserved more than 1 million acres. While funding has fluctuated in recent years, she said unstable funding could impede critical habitat purchases as development pressures increase.

In 2010, Wraithmell led Audubon’s response to the Deepwater Horizon oil spill, advocating for restoration settlement funds to be directed toward coastal bird habitat recovery. Her efforts earned her the Charles H. Callison Award in 2015, the highest honor from the National Audubon Society.
Wraithmell does not shy away from the topic of climate change.
“The ocean is coming for us,” Wraithmell said. “Whether you call it climate change, sea-level rise or flooding, we are seeing the impacts on our shorebirds and our coastal communities right now.”
Under her leadership, Audubon Florida has expanded coastal resilience efforts, including protecting nesting grounds threatened by rising sea levels and promoting nature-based solutions such as wetland restoration and living shorelines. Alvi said many people underestimate how difficult it is to align science, policy timing and organizational reputation simultaneously.
“The most significant win will likely be institutional strength: a conservation movement in Florida that is more strategic, more science-driven and more disciplined in its public engagement,” Alvi said.
When asked to summarize Florida’s environmental story in a single place, Wraithmell pointed to the Everglades. She described it as an ecosystem shaped by historical “screw-ups,” from ditching and draining to the exploitation of birds.
“It’s a site of people coming together and saying, ‘Whoop, we screwed up. Now what are we going to do about it?’” Wraithmell said. “With billions of dollars in investment, we are seeing results.”
Despite the rapid pace of development across Florida, Wraithmell remains optimistic about the future, pointing to volunteers, students, and local advocates who make up the Audubon Florida network.
“Watching kind of the creative magic that they get up to together,” Wraithmell said. “That is what gives me hope for the next decade.”
The little girl watching from the ground is gone. Now, Julie Wraithmell is the one in the treetop, asking young Floridians to climb with her and protect wild Florida.

Florida Democrats flipped two legislative seats in 2026 special election, their best performance in years
Florida Democrats had their best election night in years Tuesday, flipping two legislative seats.
Analysts and politicians point to the combination of strong candidates, low turnout special elections, rising gas prices compounding existing affordability issues and the ongoing conflict in Iran, which helped offset the registration and financial advantages of Republicans.
Also, historically, an unpopular president heading towards the midterm elections is always tricky for the party in power.
These factors may justify some optimism for the minority party in the state heading into the November election cycle, which could see rematches from Tuesday’s contests.
University of Central Florida political science professor Aubrey Jewett said at the campaign level Florida Democrats did a good job getting solid candidates who didn’t make mistakes and stuck to the message of affordability.
Also, there is the timing, as historically the sitting president’s party more often loses seats in midterm elections at the congressional and state legislative levels. Jewett added that unpopular presidents lose even more seats, noting that since the 2024 presidential election, Democrats have flipped more than two dozen seats in Republican or battleground states.
“President Trump’s unpopularity cast a long, dark shadow over these Republican candidates in these races,” Jewett said. “And so, even if you had decent candidates, it was just too much of an uphill battle because of President Trump’s unpopularity.”
One of those Democrats who won did so in a district that includes Trump’s Mar-a-lago estate
Democrat Emily Gregory of Jupiter led by 2.38 percentage points with 33,429 ballots cast in the House District 87 contest along the east coast of Palm Beach County. The district includes the home of President Donald Trump.
Gregory is a Treasure Coast native, a military spouse and mother of three with a master’s degree in public health from Columbia University who operates a small fitness business.
Tampa Democrat Brian Nathan, a U.S. Navy veteran and organizer with the International Brotherhood of Electrical Workers, was up 0.51 percentage points in the state Senate District 14 contest in Hillsborough County, where 80,016 votes were cast.
The results remain unofficial.
Republican Hilary Holley easily won the third legislative special election, House District 51 in Polk County, by more than 8 percentage points.
In the Tampa State Senate race, Jewett said there was evidence that Republicans seemed to be doing well in early voting, noting GOP candidate Josie Tomkow, a former House member, had good name recognition and funding.
“But it appears that the Democrats that turn out were strongly unified and (no party affiliation voters) must have gone strongly Democratic as well — and it seems likely that at least some Republicans voted Democratic,” Jewett said.
House Speaker-designate Sam Garrison, R-Fleming Island, who led GOP efforts for the House special elections, issued a statement Tuesday night that Republican Jon Maples ran an “extremely strong campaign” for the Palm Beach County seat, but faced “low Republican turnout due to awkward special election timing,” and also questioned “despicable, dark-money” attacks against the candidate.
Garrison added, “We will learn from today’s results and see you in November.”
Florida Republican and Democratic party chairs react to the election’s results
Republican Party of Florida Chairman Evan Power said the party is “proud” of its special election candidates and will continue to “engage, mobilize and lead.”
“Republicans are leading on the issues that matter the most to Floridians — public safety, economic growth, meaningful property tax reform, expanded school choice, and strong environmental stewardship,” Power said in a statement. “Our record isn’t just strong, it is unmatched. With a Republican voter registration advantage of nearly 1.5 million, we are well-positioned and fully energized as we head toward November.”
Florida Democratic Party Chairwoman Nikki Fried hopes the result makes Republican lawmakers pause as they approach Gov. Ron DeSantis’ call for a special session to redraw congressional district lines the week of April 20.
“Voters are tired of one-party rule and attempts to steal their votes,” Fried said in a conference call Wednesday with reporters. “They are tired of the skyrocketing costs and the chaos in the news this year.”
Fried also said the state party, which still faces a need to cut into the Republican supermajorities in the Legislature in the fall election, has been on the phones with national Democratic groups that have disengaged from Florida politics the past couple of cycles.
