#GreatWhiteSharks are overheating
The #sharks might also be most physiologically vulnerable to warming waters.
Several large tuna species and sharks, known as “#mesothermic” species for the way their bodies run hot, require more fuel to maintain their temperature and are thus confronting a “double jeopardy” of warming oceans and declining food, mainly from overfishing. As water temperatures climb, these species will be forced to relocate to cooler waters.

Huge relatives of white #sharks lived earlier than thought
8m “megapredator” sharks patrolled #Australia's seas 115 million years ago
Pushes back age of earliest giant #lamniform sharks — kin to #greatwhitesharks and Otodus #megalodon — by 15 million yr
“These sharks were serious contenders, playing the role of apex predators alongside dominant megafauna such as marine reptiles,” says Mohamad Bazzi, an evolutionary biologist at Stanford University

🦈⚔️ Researchers in #Mexico's Gulf of California filmed #orcas hunting juvenile great white #sharks using a sophisticated strategy that exploits the sharks' tonic immobility response. The orcas coordinate attacks to flip sharks upside down, then harvest their energy-rich livers and share the prize among their pod, including calves.

Great white sharks are perhaps the most feared predators in the ocean. But what might they fear? Probably orcas. In the Gulf of California, the killer whales have been spotted hunting young great whites by flipping them over before eating their energy-filled liver. Blech. It’s wild out there. @CBSNews has the story:

In #Mexico, #KillerWhales Take Down #GreatWhiteSharks
A pod of #orcas in the Gulf of California has repeatedly hunted juvenile white #sharks to feast on their livers.
Scientists had previously found evidence that killer #whales prey on one of the ocean’s top predators; several years ago, white shark carcasses without livers washed ashore in South Africa. But the behavior had not been documented in Mexico until now.

#GreatWhiteSharks split into 3 populations 200,000 years ago and never mixed again — except for one hybrid found in #BermudaTriangle
Scientists found 3 great white #shark populations that congregate in different #oceans and do not interbreed. Their separation may have implications for conservation.
Unclear why populations split in first place. Researchers suspect drop in #sealevel and changes in ocean currents and temperature created biogeographical barrier for sharks.

A wildlife filmmaker and biology student appear to have captured the first-known footage of a newborn great white shark. Read about it at Science Alert, and watch video of the moment, among many others, caught by a drone camera off the coast of Santa Barbara, Calif. https://flip.it/uME2nw
