Abstract

A total of 13 enzymes, coded by 14 loci, were successfully examined by horizontal starch gel electrophoresis in the intertidal dorid nudibranchs Adalaria proxima (Alder & Hancock) and Onchidoris muricata (Muller). The derived genetic identity and similarity values provided estimates more typical of congeneric, than only confamilial, species. The suggestion is that these two species hold a recent common ancestry, and that Adalaria proxima (with its more advanced, pelagic lecithotrophic larva) is an evolutionary derivative of the Onchidoris muricata stock. At least three loci (Pgm and Fum, A. proxima; Pep-2, O. muricata) are all highly polymorphic.
