Is this a San Diego dorid with a lot of spots? It was shot in CA, Channel Islands.
Wish I had more info but it was shot on film and I was never good about keeping logs.

Thanks,

Todd

Nope, not San Diego.

Peltodoris Mullineri.

Nice pair of P. mullineri, Todd. Sometimes this species is confused with Jorunna pardus, whose rhinophores and branchial plume is colored dark brown (confused me when I saw my first J. pardus @ Catalina). I note your specimens have some brown coloration on the rhinophores (instead of solid yellow/orange), which I've not seen before but still agree with Jim that these are mullineri.

Cheers, k;-)

Right on. Best way to distinguish these two dorids is gill. P. mullineri is light, while J. pardus is dark, almost black. Both these species have caryophllidia (papillations) on the dorsum, whereas Diaulula appears almost smooth.
