On to some of the more tricky species to identify. The rock overhangs, the home of the Painted top shells, are covered in sponges, tunicates and bryozoans. These are organisms I need to spend some more time on, as they are diverse, pretty and easy to photograph (they do not scurry away or give any macro depth-of-field problems). First two pictures of the large, nicely textured sponge Ophlispongia papilla. After that, the cream-coloured sponge Dysidea fragilis and the yellow sponge Aplysilla sulfurea. Side-by-side the bryozoan Disporella hispidata and what might be the sponge Clathrina coriacea.

There were quite a lot of other sponges and bryozoans to see as well, so I’ll definitely investigate more the next low tide. Some other species: the tiny polychaete worm Euphrosine foliosa (first two pics). Next, Chaetopterus variopedatus, a quite large polychaete worm (thanks to David Fenwick for the ID), a tiny glossy bivalve Kellia suborbicularis (thanks to David again) and what is probably a Chameleon prawn Hippolyte varians.
