This nudibranch mainly feeds on sponges. These sponges allow it to secrete a toxin that allows it to defend itself against shrimp attacks for example.
It's a nudibranch quite easy to find, quite big and colorful.
Mammals have a horizontal tail.
Fishes have a vertical fin.
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 whale shark is the largest fish in the world!
Some whales are larger, but they are mammals, not fish!
