A new study found that sharks born into environments degraded by human-induced stressors develop more slowly than those who grow up in more pristine habitats.
Shark Talks: Shark Ecologist Bradley Strickland
With the Atlantic hurricane season in it peak, one of the questions we have been running across frequently is “what do sharks do during a catastrophic weather event.” To find out, we reached out to Bradley Strickland, a doctoral student at Florida International University in Miami. One of Strickland’s area’s of research includes a long-term […]
Mako sharks’ migration shows impressive sense of memory
Tracking data off the western coast of the United States showed how advanced mako sharks’ sense of navigation and site memory really is.
Prehistoric sharks were suckers for crustaceans
A new study by the University of Chicago found that a prevalent species of 335-million-year-old shark had sophisticated jaws that functioned in much the same way as modern nurse sharks. Researchers used CT scans of fossils embedded deep in rock to create 3-D models of the movements and mechanics of the prehistoric sharks. The findings […]
Researchers uncover secret to glowing sharks
Researchers have identified a previously unknown family of small-molecule metabolite that is responsible for the bioflourescence of deepwater sharks that allows them to see each other in the darkest of depths. David Gruber, a professor at City University of New York, and Jason Crawford, a professor at Yale University, extracted chemicals from the skin samples of […]
Blue sharks reveal secret ocean buffets for large predators
A new study by the Woods Hole Oceanographic Institution and the Applied Physics Lab at the University of Washington found that sharks ride fast-moving currents to dive to depths where prey is plentiful. Using satellite tags attached to more than a dozen blue sharks off the Northeast Coast of the U.S., the researchers found that […]
Study: More people, less sharks
A new study found that are sharks are much rarer in habitats near large human populations and fish markets. A team of researchers, led by the Zoological Society of London, found that that the average body size and number of sharks and other marine predators fell significantly in proximity to cities with more than 10,000 people […]
Automated drones follow basking sharks in the UK
In a first for the research and study of basking sharks off the coast of western Scotland, SharkCam followed basking sharks to discover more about the world’s second largest species of shark. The REMUS SharkCam technology from the Woods Hole Oceanographic Institution was used to observe the behavior of basking sharks in the Inner Hebrides […]
Shark metabolism may hold key to species survival
According to a new study by the University of Queensland, the internal energy flow of large sharks and rays could be essential to surviving climate change. University of Queensland Ph.D. candidate Christopher Lawson found that bioenergetics of sharks and rays will determine the animals ability to adjust to temperature changes in historical habitats “Shark and rays […]
Shark data lacking for Western Indian Ocean
Great white sharks, bull sharks, tiger sharks: All are household names, synonymous with media hype, and made infamous through films and documentaries. These “deadly” names represent just three species of sharks and, aside from the real shark nerds, few people are able to name many others. Yet, globally, there are over 1,250 species of sharks […]
