Dear Bill,
Thanks for the identification.

Here are a few more pictures of Hancockia californica taken from a different angle. I hope that these will be of some help. As to the size of the critter that I photographed, I believe that it was about 7mm in length. This measurement can be verified by Dave Behrens (I sent him the specimen).

Thanks again for a wonderful site.

Dear Sean
Thanks for this extra photo. You can see one of the rhinophores with the cup-shaped sheath and one of the finger-like oral 'tentacles' much like the ones on Bornella.

It is also a spectacular view of the hydroid colony, You can see the root-like stolons forming a network over the rock, the individual polyp animals on long thin stalks and the fat gonotheca which are the specialised reproductive polyps which form the free-swimming medusoid generation of these strange plant-like animals.

Best wishes
Bill Rudman
