" Each species we can meet underwater has very intereseting specificities.
It is a part of a world that doesn't work like ours and that we have to preserve.
To help to preserve it, we decided to create Ananahi: a library of informations around trips we made and species we have seen while diving. "

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.
Mammals have a horizontal tail.
Fishes have a vertical fin.
