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 […]
Madagascar a playground for young whale sharks
By Nora Ward, Mongabay.com Whale sharks don’t need help being spectacular. The world’s biggest fish is impressive in nearly every aspect, growing as long as 12 meters (40 feet) and weighing up to 21 tons. Their enormous mouths contain thousands of teeth, and their backs feature constellations of white spots that make them look like […]
The Conversation: Coexistence or culling in Cape Cod?

García-Quijano, University of Rhode Island Interactions between people and animals offer insights into human culture and societies’ core values. This is especially true with respect to large predators – perhaps due to a collective memory of our evolutionary past as hunted […]
Basking sharks have aerial breaching capabilities
Basking sharks may not be the lazy, lumbering ocean dwellers that they appear to be. A new study by researchers at Trinity College in Dublin and published in this month’s journal of Biology Letters, found that basking sharks have the same aerial capability as great white sharks when it comes to breaching out of the water. Basking […]
Researchers use tooth DNA to identify shark involved in NY bite
University of Florida researchers used DNA extracted from a tooth fragment pulled from the leg of a shark bite victim to identify the species involved in an incident involving a 13-year-old boy off the coast of New York. “We’re as close to 100 percent sure as we can get that this shark was a sand […]
Doctors use botox injection on sand tiger shark
A dermatologist may have devised a novel treatment for scoliosis occurring in sharks. Charles E. Crutchfield III, MD, along with the Minnesota Zoo’s veterinary staff, injected botox into a captive sand tiger shark that was suffering from scoliosis. Sharks in the wild, as well as in human care, can develop scoliosis. Some types of scoliosis are […]
Shark bites man off coast of Florida
An elderly man was severely injured after a shark bit him on the leg in the waters of Fort Pierce Inlet State Park, according to the St. Lucie County Fire District. The unidentified man was surfing near the inlet on Friday when he was bitten. “Our lifeguards said it was a pretty significant-sized bite below the knee […]
Study: Mass extinction led to shark diversity
A new study conducted by researchers from Uppsala University in Sweden and the University of New England in Australia, and published this week in Current Biology, suggests that modern shark biodiversity was triggered by the end-Cretaceous mass extinction event about 66 million years ago. As part of the study, researchers explored how certain groups of sharks responded to […]
New 3D printing technology could aid shark bite survivors
University of Nebraska–Lincoln researchers—including Ali Tamayol and Prahalada Rao—are working on a technology that could enable 3D printing of tissue that could aid the recovery of shark bite survivors. “Today, if you lose a leg, shatter a knee or break a bone, we can print custom replacement implants,” said Rao, assistant professor of mechanical and […]
Analysis shows some sharks still vulnerable to fishing pressure
A new study from the University of Miami Rosenstiel School of Marine and Atmospheric Science found that despite the habitats’ of several vulnerable species of sharks being “relatively well protected from longline fishing,” there are still areas in the Southeast United States where the sharks continue to face fishing pressure. The new study, which focused on great […]
