The opisthobranchs are sea hares and sea slugs, soft-bodied, snail-like mollusks that either have a vestigal shell or no shell at all. Their taxonomy is difficult, their position in the phylum Mollusca is hardly agreed upon by experts, but they are so beautiful and interesting that a seashore naturalist finds them hard to resist.

M-980 SEA HARE, Aplysia brasiliana, the most active, graceful, and best surviving of all the species of Aplysia. Aplysia is commonly studied by researchers for its easily accessible giant ganglia. Releases a purple ink when disturbed. Most unfortunately however, the mollusks are highly sporadic, appearing in huge numbers some years and completely unavailable in other years. Researchers are advised to place long term standing orders to insure a supply. Size: 6-10 cm.
Each: $28.00

M-990 FRILLED SEA HARE, Bursatella leachii, a large, highly frilled, shelless snail, gray green with white specks. Surface covered with numerous ragged projections. When disturbed ejects a cloud of purple ink. Actively slides along the aquarium wall feeding on algae and often lays long strings of greenish eggs. Has exceptionally large radular teeth in crop, good for dissection. Sporadically available, mostly in winter. Size: 8-12 cm.
Each: $28.00

M-995 LETTUCE NUDIBRANCH, Tridachia crispata, Commonly found in warm, tropical waters, it has green and white ruffles resembling lettuce! Feeds on real sea lettuce and other algae. It is one of the few nudibranchs that are vegetarians, and does not feed on sponges or hydroids. Size: 4-6 cm.
Each: $24.00

M-1010 TIGER NUDIBRANCH, Hypselodoris edenticulata, a beautiful dark blue nudibranch with striking yellow circles. Sporadically available; may be substituted by other large and colorful nudibranches. Size: 4-8 cm.
Each: $28.00

M-1020 NUDIBRANCH ASSORTMENT, Nudibranchs are shelless mollusks and can be extremely beautiful in color and shape. Eolids are well known for their ability to feed on hydroid polyps, absorb the nematocysts without harm, and utilize them in their own defense. Shipments may often include Doris verrucosa, which feeds on sponges.
