Photos of Polycera atra

Hi Doc,
Here are some photos of Polycera atra. The upper and lower right are of P. atra feeding on the bryozoan Bugula, and the lower right is of three together laying eggs.  These are the most common nudibranchs in Shaw's Cove, Laguna Beach California.  We see them almost every dive (saw three in Shaw's this morning in fact).  They are easy to find, for all you need to do is look in the clumps of Bugula and you will either see the white ribbon eggmass, telling you to look closer or you will see the animals feeding on the outer edges.  They are normally found in groups and seldom see individually. They vary in size from the juveniles being less than 1/4 inch to the adults which are around 3/4 to 1 inch in length.

Hope these will help you,
Bruce Wight

Thanks very much Bruce,
Your juvenile certainly has a bit of growing to do.
Best wishes,
