Looking amongst the algae......

There are a variety of organisms that you can see whilst rock pooling. Marine algae are the most obvious; look among and under the fronds to reveal the understory communities comprised of molluscs, crustaceans, cnidarians, sponges, bryozoans and polychaetes worms.

Kelp, are marine algae which develop holdfasts inorder to attach to rock. Inspect the holdfasts of washed up kelp and you will discover organisms living within the holdfast.

and bivalves of the family Anomiidae.
