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.
Parrotfish create a protective envelope around them when they are sleeping.
So, don't put the light on them during night dive to don't to wake them up and break this envelope.
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.
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.
