Hi again Doc.
To answer your question about the size of the animals in the photos is between 3/8" and 1/2" [10-12mm]. They are all juveniles, which are characterized in this species by the underdeveloped bulbous cerata and small size. The UPPER photo is an adult which has longer more elegant looking cerata. I often times see the juveniles without the white striping, but I have never seen an adult without it. That mimic crustacean on your site is incredible, are they seen down in Southern California or just farther north?

Hope you enjoy the images,
take care

Dear Bruce,
Thanks for the great photos of the adult and unlined juvenile, which clearly has lamellate rhinophores. From Jeff Goddard's message it seems his crustacean mimic is in Oregon but there is another colour form which mimics Flabellina iodinea in central California.

I will post your photos of Ancula and Hopkinsia as separate messages.

Best wishes,
Bill Rudman.
