It is particular to rough waters with little light. As a result, it can be spotted close to the surface, under rocky overhangs and at the entrance to caves.
Corynactis often sport bright colours: greens, purples, oranges, pinks and so on. Their 100 or so tentacles are arranged in three rings around the mouth, with the longest on the outer rim. They have a slight swelling in a colour that contrasts with the rest of the body.
In addition to its ability to reproduce sexually between a male and a female, the corynactis can also reproduce asexually, by budding. In other words, a single individual can give birth to an entire 'colony' of genetically identical animals.
These colonies can sometimes cover up to several square metres. As a result, corynactis often make up large swathes of juxtaposed colours.
