This nudibranch is often in pairs and often close together, the head of one touching the tail of the other.
It is also one of the only chromodorididae that can make its gills vibrate ( we do not know why ... :p)
Mammals have a horizontal tail.
Fishes have a vertical fin.
The whale shark is the largest fish in the world!
Some whales are larger, but they are mammals, not fish!
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.
