Aiptasia mutabilis?
Hi,
I saw this very small anemone under a pebble in shallow water. Could it be a young Aiptaisia mutabilis or another species please? I assume that the purple organism is Cystodytes dellachiajei.
Thank you very much for your help. I have learnt so much through this site!

Porifera or ...?
Hi,
I found these two species encrusting the underside of a pebble in very shallow water. The pink one was ca 12cm wide and the white one was ca 6cm. What animal groups are they? I can't see whether they are porifera or bryozoan, or maybe neither. Would be grateful for expert help. Thank you very much.

Quel bivalve?
Hi,
This bivalve was on rocky substrate in the littoral zone. When they are embedded like this I find it hard to identify them from a guide book, where they are presented "clean". Any help is identified, if at all possible.
Thank you!

Que sont-ils?
Hello,
I found these small orange things on his hydroid. Are they part of the animal, or something else? Identification of the hydroid itself would be appreciated.
Thank you very much.

What are they?
Hi,
These strange objects were growing on a vertical rock shelf at 1m depth in low light. They seem to be animals, but the photo is not very good. I seem to see tentacles growing out of each green square. Any help is appreciated.
Thank you.

Quel nudibranche?
Hello,
I found this 1cm nudibranch about 1m below the surface on a vertical rock face. I've seen Felimida britoi. Felimida luteorosea and Elysia timida here, but this is a new one to me. Any ideas please? Thank you.

Nudibranche ou..?
Hello,
I originally thought this was a young Pinctada radiata. On processing photos I saw something that actually looks like a nudibranch, especially the "head' on the right, and some hairs on the "neck". Can anyone solve the mystery please? Thank you
