Just in time for shark week, scientists have discovered a massive swarm of sharks just chilling at extremely hot temperatures near Kavachi, a highly active volcano off the coast of New Guinea.

This is not normal behavior, at all.

The National Geographic Society/Waitt Grants Program’s Brennan Phillips says, "It makes you question what type of extreme environment these animals are adapted to. What sort of changes have they undergone? Are there only certain animals that can withstand it? It is so black and white when you see a human being not able to get anywhere near where these sharks are able to go.”

Mutants or not, its a pretty incredible ecosystem.
