This fish is very shy and often flees the diver who approaches him.
When he thinks being in danger, the porcupine fish swells with water to grow and look like a round ball full of thorns. This allows him to defend himself and go hide.
Some sharks can stay motionless on the sand (white tips reef sharks, nurse sharks, etc.).
These sharks don't have to swim to bring oxygen to their gills like other sharks (grey, hammerheads tc.)
We can hear the bull shark is very dangerous because of attacks near La Réunion island.
However, tens of them are living at 600 feet from the famous beach of Playa Del Carmen in Mexico. And there are no attacks.
Mammals have a horizontal tail.
Fishes have a vertical fin.
