This phyllidiid nudibranch species is currently known from Micronesia, Papua new Guinea, Fiji and now Indonesia. It was named in honour of Clay Calson and Patty-Jo Hoff; two wonderful people who are the most professional of 'amateurs' with one of the best private slug collections, and undoubdtly the best 'backyard' (coral reef) on earth!
Phyllidia carlsonhoffi is charcterised by alternating large and very small
tubercles which are isolated (not coalesced or joined by a ridge as in P.
varicosa and P. coelestis). The tubercles have blue bases but are tipped in
bright yellow. The rhinophores are also bright yellow. Ventrally, it also
has remarkably long oral tentacles tipped in yellow and a black midline
foot stripe (like P. varicosa). As in all phyllidiid nudibranchs, the gills
are consist of rows of leaflets which are found ventrally, running
longitudinally on both sides between mantle and foot. Phyllidia
carlsonhoffi is superficially similar to P. madangensis - probably for the
added protection of mimicing a like, badly-tasting, species (the phenomen
of aposematism discussed previously by Terry Gosliner, Bill Rudman and
myself). P. madangensis however lacks the foot stripe, does not have the
alternating pattern of large and small tubercles, has short oral tentacles
and substantial differences to the oral tube internally.

Douglas is a successful photojournalist and video maker. He has won 15 international awards for photography and been published in American, Austrailian, Asian, Japanese, and Indonesian magazines. SDJ was the first Chinese diving magazine to publish his works.
Doug and Mieko are planning to open an E-6 processing service for underwater photographers in the Manado area on the northern tip of Sulawesi in Indonesia sometime in early '99. So if you happen to be in the area and aren't sure whether your TTL or strobes are doing the job, give Doug and Mieko a couple of test rolls to develop!!
