This fish lives in open water, on the surface or often in deep lagoons or near steep slopes.
He lives on a shoal and has diurnal activity. We can see in these shoals its close parent (Caesio teres), to distinguish them we must look at the yellow part which is different in the Teres according to the age and which starts from the caudal diagonally.
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.
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.)
Mammals have a horizontal tail.
Fishes have a vertical fin.
