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 […]
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 […]
The Meg! When the (giant prehistoric) shark bites, the science bites back

With a cast led by Jason Statham, this is a big-budget version of several megalodon movies that have popped out over the […]
Study shows how evolution may shape sharks’ senses
A recent study explored how shark’s electrosensing organ reacts when it detects tiny electrical fields emanating from nearby prey. The study, funded by the National Institutes of Health and published in the journal “Nature,” was conducted by David Julius, Ph.D., professor and chair of physiology at the University of California, San Francisco, and post-docs Nicholas W. Bellono, […]
Whale shark study reveals new insights on lifespan
A long-term study has revealed that whale sharks, the largest fish on the planet can live upwards of 130 years. Researchers from Nova Southeastern University’s Guy Harvey Research Institute and the Maldives Whale Shark Research Programme published their findings on whale shark aging growth dynamics in the latest Marine and Freshwater Research Journal. The ten year study was […]
