Info

Isanthus capensis is a rather small anemone that attaches itself to small stones and gravel.
A look at photo A reveals two distinctly darker, brownish tentacles lying on opposite sides of the mouth disc, these two tentacles are the anemone's tentacles of capture!
In total the anemone has 48 tentacles.

Interesting is also the distribution of this species, it would be exciting to know how this anemone is known "only" from Korea, the west coast of the USA (East Pacific) and South Africa, or how it could get "only" there"?

The anemone is a so-called internal breeder, i.e., offspring develops safely in the adult anemone, moreover Isanthus capensis is considered a sequential hermaphrodite.
