With a reported top speed of 74 kilometers per hour (46 miles per hour), the shortfin mako (Isurus oxyrinchus) is one of the fastest creatures in the sea. It can jump up to 9 meters (30 feet) out of the water; its unique skin has inspired developments in the aeronautics industry; and with one of […]
New species of prehistoric shark discovered in South Carolina
A new species of prehistoric daggernose shark was recently discovered among a trove of prehistoric fossils found in Aiken County, South Carolina. David Cicimurri, curator of the South Carolina State Museum’s natural history collection, and James Knight, of the University of South Carolina Aiken Department of Biology and Geology, found numerous fossils in the formerly […]
Rhino rays receive overwhelming support for new trade regulations
In what conservation groups are calling a major win, governments from around the world have voted to regulate the international trade in two species of mako sharks, six giant guitarfish species, and 10 species of wedgefish. All 18 species have now been formally approved for listing on Appendix II of the Convention on International Trade […]
CITES Conference results in new protection for sharks
More than a dozen new species of sharks received additional protections after the 18th Convention on International Trade in Endangered Species of Wild Fauna and Flora Conference of the Parties held this week in Geneva, Switzerland. “Previous successful listing of shark and ray species means there is building momentum for CITES to provide protections and inspire fisheries […]
SharkoFiles: Ghost Shark
This species are formally known as chimeras and informally as the spookfish. They are a small group of cartilaginous fishes. This species of sharks have been around for over 400 million years. Although they are called ghost sharks, they are not true sharks. These species spent most their time below the sea at a depth […]
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 […]
The Conversation: Sharks aren’t a reason to panic
By Gavin Naylor, University of Florida Sharks elicit outsized fear, even though the risk of a shark bite is infinitesimally small. As a marine biologist and director of the Florida Program for Shark Research, I oversee the International Shark Attack File – a global record of reported shark bites that has been maintained continuously since […]
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 […]
