Image of brooding anemone

Description:

A lot of these on one piece of seaweed. Also found the other brooding anemone together with one of these on the same piece of seaweed (see 6th photo). The larger one is often identified a C. nutrix too, but I have no idea why apart from the fact it is also a brooding anemone and found in the same places - that one looks like an Epiactis species to me.
