Anemones of the type "entacmaea" have no warts on their column.
It can move, when we see some who are more than 15.8 inches, it is often young people from 2 to 4 inches who have gathered.
Two hypotheses for the bulb at the end of the tentacles: either the absorption of light creates this bulb and shrinks the tentacle, or it would be in reaction to the presence of symbiotic damselflies.
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!
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.)
