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 […]
Guy Harvey Institute tracking new whale shark in Atlantic
Researchers from Nova Southeastern University’s Guy Harvey Research Institute are learning new details of the whale sharks’ migration patterns thanks to its latest tagged shark, Lady Rio. In the ten months since it was tagged the adult female has made two round-trip journeys into the Caribbean and Gulf of Mexico, only to return to nearly […]
OCEARCH tracks four sharks from Nova Scotia expedition
Four of the sharks tagged during OCEARCH’s Nova Scotia Expedition in 2018 — Luna, a 15-foot female; Cabot, a 9-ft, 8-in male; Hal, a 12-ft, 6-in male, and Jane, a 10-foot female –have already returned to Shelburne and Yarmouth Counties as of this week. Their return to the Canadian province is more evidence that Canada […]
Study maps evolution of sharks through their teeth
The family of mackerel sharks, from the modern mako to the prehistoric megalodon, can be traced back to a modest common ancestor, according to a new study by the University of Vienna, Austria. The study, which was published in the recent journal Scientific Reports, looked at tooth samples from the great white and other members of […]
New satellite tracking tags tested on tiger sharks
New satellite tracking technology developed by the European Space Agency for the study of sharks are now being tested on four tiger sharks that were caught and tagged in the Dutch Caribbean. The new satellite tags, which records pressure—indicating the depth of the shark—temperature, light level and tilt to enable three-dimensional mapping, is smaller and […]
New species of pocket shark discovered
A new species of pocket shark that can emit clouds of fluorescent glowing liquid has been identified thanks to an analysis by the Royal D. Suttkus Fish Collection at the Tulane University Biodiversity Research Institute. The 5½-inch male kitefin shark, which was caught in the Gulf of Mexico in February 2010, has been identified as the […]
Plastics, ocean trash a growing threat to sharks
A new study by Exeter University found that discarded plastic, derelict fishing gear and other man-made oceanic trash may pose a bigger threat to apex predators like sharks than previously thought. The paper was published in the latest issue of the journal Endangered Species Research. Entanglement—mostly involving lost or discarded fishing gear—is a “far lesser threat” to sharks and […]
