Aplysia parvula is probably the smallest species of Aplysia, reaching a maximium length of about 6cm. It's colour is very variable, mottled red-brown, green or black, the large parapodial flaps have a black and/or a whitish edge. Here is a 3 mm juvenile specimen. I did not know, that Aplysia parvula grows the oral tentacles first, that is why the eye spots look somehow misplaced, the rhinophores grow later behind the eye spots.
Many pictures of specimens starting with 1.5 mm over 2 mm and 3.8 mm etc. are at Sea Slugs of Hawai'i, and the GALLERY, the 4 mm specimen has already small rhinophores!
I have posted more pictures than usual for this species to show some colour variants.
More information on Aplysia parvula are on Bill Rudman's Sea-Slug Forum!
