nudibranch Cerberilla asamusiensis Family Aeolidiidae updated Oct 10 Where seen? This tiny 'furry' nudibranch is sometimes seen on our sandy areas on our Northern shores. It is said to be quite common but infrequently encountered because it usually remains buried in the sand. Features: 1-2cm long. Broad, soft body with many long finger-like extensions (called cerata) arranged in rows. The yellow colour in the cerata is actually in the digestive glands. The rhinophores at the top of the head are very short compared to the long oral tentacles (the long tentacles that stick out on the sides like a moustache). Young nudibranchs have longer oral tentacles relative to their body size. The foot is quite broad. What does it eat? It is believed to feed on sea anemones. Cerberilla nudibranchs produce a spiral egg mass with a long string or thread at the end that is attached to something hard in the sand and thus anchor the eggs in the sand. |
