Cerberilla sp. 5 from Lizard Id, QLD

Dear Bill,
To accompany my other message with a photo of a pale Cerberilla here is a photo of a second dark species we found quite abundantly. It is Cerberilla sp. 5 on the Forum. We found the dark form regularly in November and December 2003 on sandy bottoms in 2-5 m depths at Lizard Island (QLD, Australia). Body length 7-10mm.
Regards
Nils

Thanks Nils,
It's possible it will grow into a more colourful species as it matures, because animals of this genus do tend to be brown when juvenile. However the pale coloured juvenile clearly has the markings of C. annulata so that is one species which has its distinctive colour pattern quite early in life. I think the brown animals are a different species. Apart from the colour differences, in this species the cerata seem more numerous, and they are cylindrical, whereas in the juvenile C. annulata they are fewer and quite flattened dorso-ventrally.

I would be interested in some information on their habits. Did you find them crawling at the surface or were they buried in the sand? If crawling on the surface were they only active at night? We know so little about these animals that any little bits of information are useful
Best wishes
