The most crossed reef shark in the reef. Inoffensive, it only eats small fish early in the morning or late at night (around 5am and 5pm).
This shark is very important for the reefs, it feeds effectively by eating sick fish or end of life fish and, being sedentary, prevents larger species to arrive too close to the coasts.
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.
The tiger shark has slender marks similars to the lines of tigers, hence its name.
When it is juvenile, these marks are round and not vertical. They change when it grows.
