Dear Dr. Rudman:
Two accompany our other message [#14298] on commensal behavior involving nudibranchs from Southern California, here is a record of a juvenile amphipod Podocerus sp. (either P. brasiliensis or P. cristatus, family Podoceridae) on Tritona festiva.
Unlike the scaleworms in the other message, which are known for being commensals, this amphipod was thought to be an accidental passenger by its identifier, Don Cadien.
Locality: Buchannan's Reef, Rancho Palos Verdes, California, USA. Depth: 20 metres. 17 July 2005. rocky reef. Photographer: Jim Lyle

I guess the only way we will know if there is an association or not is 'constant vigilance'.
Best wishes,
