After going off the grid for nearly nine months, Katharine the great white shark is making up for lost time. The 14-foot female’s satellite tracking device has pinged in three times in the last week roughly 70 miles off the coast of Melbourne. Earlier this year, OCEARCH researchers feared that the battery in Katharine’s satellite tag, […]
Rare footage of deepwater shark eggs in Puerto Rico
The National Oceanic and Atmospheric Administration’s remote-operated deep sea research vessel captured images of a live shark embryo inside an egg case west of Puerto Rico’s Desecheo Island. The 22-day mission by by the NOAA’s ROV Deep Discoverer explored waters around Puerto Rico and the U.S. Virgin Islands in the deepest dives ever recorded in […]
Mathematical theory explains shark scale patterns
Scientists from the University of Sheffield’s Department of Animal and Plant Sciences found that Alan Turing’s reaction-diffusion theory can unlock the secrets for the growth patterns of shark scales. The findings help explain how a shark’s skins has uniquely evolved to minimize drag while swimming. Scientists believe these pattern may help to design new synthetic materials to […]
OCEARCH concludes Nova Scotia expedition
OCEARCH’s latest expedition to has resulted in the discovery of a white shark hotspot off Nova Scotia’s South Shore. The 21-day expedition by OCEARCH and its joint team of U.S. and Canadian scientists resulted in the collection of nearly 300 biological samples samples. Six great white sharks were also affixed with satellite tags which are […]
Sharks used to predict Florida election results
Politics isn’t the place for pinfish, especially this election season in Florida, where there is blood in the water and the predators are circling. Sometimes you have to leave the polling to the sharks. Which is why Nova Southeastern University and the Guy Harvey Research Institute have brought back a team of satellite-tagged short-fin mako sharks to […]
Grant seeks to unlock mysteries of the megalodon
There’s very few things we know about the megalodon shark for certain. We know that it was one of the largest marine predators on the planet, reaching lengths of over 60 feet. We know that it first appeared in the fossil record nearly 20 million years ago and that it indisputably went extinct nearly 2.5 […]
Study: Whale sharks can live up to 130 years
We know very little about the growth and reproductive biology of whale sharks, the world’s largest fish species. Because they’re listed as Endangered on the IUCN Red List, scientists are looking for ways to fill this gap in our knowledge without overly disturbing or distressing individual whale sharks. Scientists at Nova Southeastern University (NSU) in […]
Genome sequencing could unlock secrets of shark evolution
Because of their slow rate of evolution, researchers are able to look at a shark’s DNA as a sort of “living fossil,” according to a new study by the RIKEN Center for Biosystems Dynamics Research in Japan. Scientists, led by Riken’s Shigehiro Kuraku, analyzed shark genomes using cutting-edge DNA sequencing technologies and comparative bioinformatics on three species […]
Scientists explore “White Shark Cafe” in remote Pacific
Using satellite tags and deep-water remote operated vehicles, a team of researchers were able to take a closer look at what has been dubbed as a “White Shark Cafe” in open water between California and Hawaii. The month-long expedition, which was a joint effort by scientists from Stanford University’s Hopkins Marine Station, the Monterey Bay […]
Shark poop may soon be key to surfer safety
Researchers from from UC Santa Barbara and the U.S. Geological Survey, along with members of California State University Long Beach and Central Michigan University, have found a new way to detect if large sharks — specifically great whites — had recently passed through an area. The team’s research, which used environmental DNA to track populations of […]
