This shark is rather solitary, he can live up to 37 years.
It's a hunter who feeds mainly on rays and sharks, the leopard ray being his favorite dish. It is also immune to the venom of rays.
The hammerheads' head allow them better lift and take sharper turns than other sharks. It's a very sensitive shark that can, thanks to its sensory cells (Lorenzini ampoules), detect electric fields at 5 μV / c. It repeats you at more than 0,31 miles ;).

Some whales are larger, but they are mammals, not fish!
Turtles are in economy mode when they are sleeping. If they are woken during night, they may not have enough air to return to surface.
So, please be careful during night dives!
