Scientists have developed a new way of tracking whale sharks by collecting eDNA from oceanside areas where we know that whales swim past periodically.
400 million year old fossil casts doubt on previous thoughts on shark teeth evolution
By Benedict King, Max Planck Institute for Evolutionary Anthropology; Martin Rücklin, Naturalis Biodiversity Center, and Philip C J Donoghue, University of Bristol Teeth play a central role in the ecology of most vertebrates – for catching prey, processing food and even attracting a mate. It’s no surprise that scientists such as ourselves have long been […]
Ancient Antarctic sharks store climate secrets in their teeth

However, most sharks require movement to extract oxygen through their gills. For these sharks, stationary resting is impossible. How sharks rest is a large mystery to shark science. Behaviors have been observed, but […]

New shark species reveals new link between sharks and rays
A recent study discovers a new species of shark from the late Cretaceous period with ray-like qualities. Most sharks known today are streamlined predators. Modern sharks occupy marine ecosystems across the world, but there is little difference in their shape. In their new study, Vullo et al. find that this lack of variation is not […]
Mako and shale sharks race to save their fellow sharks
SPOT satellite tags utilize the latest in ocean wildlife tracking technology to allow researchers and the public to follow the sharks online in near real-time via the GHRI Race Tracking Website.
Three new glow in the dark shark species discovered
Scientists off the coast of New Zealand discover three new deep-sea shark species. All three species glow in the dark. One of these sharks is now the largest known luminous vertebrae. Bioluminescence: When a living organism produces visible light through a chemical reaction. The phenomenon is widespread among marine life. However, this is the first […]
