Fungia scruposa

mushrrom coral

You have got to like mushroom corals.

For a start they can eat jellyfish, somehow.

Secondly they are moving coral, they inflate themselves, and then push, travelling at about 6cm per day and finally if the mouth is broken off, multiple mouths appear and battle for supremacy, where one becomes the dominant mouth and the others either break off and run away or are reabsorbed by the king mouth.
