Corallimorphs are similar to sea anemones in structure, life style and structure, unlike corals they have no skeleton.
They can reproduce very quickly to dominate areas, often carpeting large areas of dead coral.
When disturbed they can send out stinging threads that will give a nasty sting!
Some species live in the open and are seen during the day, while others are only nocturnal.
They vary from drab to bright colours. (edit) Ref: https://en.wikipedia.org/wiki/Amplexidiscus
