Apparently it's a bit of a mystery why Great White Sharks are *not* seen regularly in UK waters. Ideal temperatures, much like the southern oceans where they do swim, and plenty of seals and tourists to eat 🦈

As Oceans Warm, Great White Sharks Are Overheating

#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

Lamniform sharks such as great whites and tiger sharks are famous for their size. The first such giants evolved 15 million years earlier than thought.

🦈⚔️ 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.

There's One Predator in The Ocean Instilling Terror in Great White Sharks

There's one beast in all the ocean that strikes terror even into the heart of the great white shark, once regarded as the most fearsome predator in the sea.

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:

Videos show killer whales flipping great white sharks and eating their livers

New research suggests that a pod in the Gulf of California specializes in hunting sharks.

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.

Why Great White Sharks’ DNA Doesn’t Add Up

Great white sharks hold a baffling genetic puzzle: uniform nuclear DNA but divided mitochondrial DNA that defies migration and evolution theories. White sharks show a striking mismatch between the DNA inside their cell nuclei and the DNA within their mitochondria. For years, scientists believed this could be explained by the way great whites migrate. A [...]
