First documented tiger shark mating hub identified by UH researchers


OLOWALU (HawaiiNewsNow) – A team of shark researchers from the University of Hawaii at Manoa have solved a longstanding mystery.

Biologists from the the Hawaii Institute of Marine Biology Shark Lab have identified the first-ever documented tiger shark mating hub.

Six years of acoustic tracking data led the team to pinpoint the area at Olowalu, Maui, leading them to new discoveries about the nature and timing of tiger shark mating and its correlation to Maui’s whale calving season.

This new finding challenges the understanding of tiger sharks as purely solitary animals.

“To our knowledge, no group mating site for tiger sharks has ever been identified. This paper adds an important piece to the puzzle of tiger shark reproduction,” said Carl Meyer, co-author of the study and principal investigator of the HIMB Shark Lab.

Researchers were able to show evidence that tiger sharks have a predictable seasonal gathering of mature males and females that coincides with humpback whale calving season in Hawaii.

Until this discovery, it was unclear how or if tiger sharks came together to reproduce or if mating was just a result of random encounters.

“Tiger sharks typically roam widely in what can seem like random patterns, so finding such a strong and consistent seasonal trend in their movements around Maui was unexpected,” said Paige Wernli, lead author of the study and a graduate student in the HIMB Shark Lab.

The years-long tracking data showed a predictable seasonal presence of both mature male and female tiger sharks at Olowalu, as well as physical evidence of mating activity.

The apparent mating hub happens during the time of year when humpback whale mothers and newborn calves arrive in the area.

The Shark Lab team says the correlation could mean that the sharks are positioning themselves near foraging opportunities, like vulnerable calves or placental falls.

“Mating and foraging on humpback whales may not be mutually exclusive,” Wernli said. “And both could influence tiger shark movement patterns in Hawaii.”

The tiger shark gatherings they observed were not dense but rather diffuse, spanning several kilometers over multiple months.

“This study expands our knowledge of tiger shark mating and challenges our conventional understanding of the term ‘gathering,’” said Meyer. “Together, the results suggest that both reproduction and food availability play key roles in shaping tiger shark movements in Hawaii.”

During the six-year study, the team was able to safely catch and implant transmitters in large sharks, then keep a vast network of underwater listening stations across the main Hawaiian Islands.

In the future, the Shark Lab team plans to use tags with cameras and other data collecting capabilities to document both their mating behaviors and shark-whale interactions.

This work was funded by the Hawaii Department of Land and Natural Resources and the Pacific Islands Ocean Observing System.

Redesigned Hawaii IDs begin rolling out statewide


HONOLULU (HawaiiNewsNow) – Newly redesigned Hawaii driver’s licenses and state IDs are beginning to arrive in mailboxes statewide.

The Department of Customer Services said more than 50,000 residents who renewed or obtained a license or state ID starting in mid-May began receiving the new cards last Friday.

Officials said the updated cards are made of 100% polycarbonate, with laser-engraved photos and added security features intended to deter tampering, fraud and identity theft.

The department said existing driver’s licenses and state IDs remain valid until their expiration dates and do not need to be replaced.

“There’s no reason for them to request a duplicate unless they would like the new card design,” said Kim Hashiro, director of the Department of Customer Services.

Residents were also reminded that temporary paper licenses are not accepted by the Transportation Security Administration for air travel. Travelers using a temporary credential should bring another acceptable form of identification, such as a passport.

Permanent plastic cards are typically mailed within six to eight weeks after an application is submitted, officials said.

Lahaina dive shop to reopen after nearly three-year closure


HONOLULU (HawaiiNewsNow) – A Maui dive shop will welcome customers back this weekend after its Lahaina storefront was destroyed in the 2023 wildfires.

Maui Diving & Sporting Goods will hold a grand opening on Ulupono Street on Saturday, beginning at 9:30 a.m.

“Losing the shop in the fire broke my heart, but reopening in Lahaina was never in question,” said store owner Jessica Pickering. “This town gave me everything I have right now. Rebuilding right here in Lahaina is my way of saying we’re still standing, we’re still here for our community, and we’re ready to enjoy this life with you.”

The business will offer the same services it’s known for at the new locations, including scuba instruction, guided dives, snorkel tours, freediving, as well as gear rentals and sales.
