When disturbed, this nudibranch can swim in the water to put a little distance with the disturbing individual. This swim is very beautiful and looks like a dance. If we add the bright red color, it looks like a flamenco dancer, hence her name of Spanish dancer.
We can sometimes find among its gills a very beautiful shrimp: the Zenopontonia rex.
This nudibranch feeds on sponges. It's in some of these sponges that he finds the repulsive that he also uses to protect himself.
The Spanish dancer hides in the corals during the day and is visible during the night. The day we can find juveniles.
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.)
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.
The whale shark is the largest fish in the world!
Some whales are larger, but they are mammals, not fish!
