Family Phyllidiidae
: identified by their warty bodies and placement of gills (between the mantle and foot, not the dorsum). Tough-bodied. Mainly feeders on sponges. Noted for releasing toxins in aquariums that are toxic to fishes and crustaceans. 

Phyllidia arabica,  Ehrenberg 1831.Off of Pulau Redang, Malaysia, and N. Sulawesi. Is this the same species as P. varicosa? Appears so: http://www.seaslugforum.net/search.cfm?searchstring=Phyllidia+varicosa

Phyllidia coelestis Bergh 1905. South Africa, China Sea, Australia, Fiji. To 6 cm. Similar to P. verrucosa, but distinguishable by P. coelistis divided black markings. N. Sulawesi image. 

Phyllidia elegans Bergh 1869. Red Sea to Maldives, to Fiji, Australia. One in Bunaken/Manado/Sulawesi/Indonesia, another from S. Sulawesi.

Phyllidia ocellata Yonow & Debelius 1991. Highly variable in appearance over its wide range in the Indo-Pacific. One in Fiji, N. Sulawesi far right and below. 
http://www.seaslugforum.net/search.cfm?searchstring=Phyllidia+ocellata

Phyllidia varicosa. Red Sea to Hawai'i. To nearly three inches in length. One in Bunaken/Manado/Sulawesi/Indonesia, one in Hawai'i, and a third in Nuka Hiva, Marquesas.  The middle one is about three inches in length.
Phyllidiella pustulosa (Cuvier 1804). Black body with pink tuberculations arranged in rows to clusters. Common from the Red Sea to Hawai'i. One in Fiji, another in Hawai'i.

Phyllidiopsis annae. Thailand, New Guinea. Blue and black body color, three longitudinal body ridges. Small... to 1.5 cm. in length. N. Sulawesi image. 

Phyllidiopsis fissuratus, Thailand, Fiji to Australia. Images made off of Bunaken/Manado/Sulawesi/Indonesia.  To eight cm. 

Phyllidiopsis shireenae. Indo-Pacific; Maldives to Solomon Islands. Distinctive mid-body crest/rise. To ten cm. N. & S. Sulawesi pix. 
http://www.seaslugforum.net/factsheet.cfm?base=phylshir

Reticulidia halgerda Brunckhorst & Burn 1990. Black body, raised orange ridges with white borders are distinctive. Similar to Halgerda spp., but lack the circum-anal gills of the latter. Fiji image. 

Family Polyceridae, Polycerid Dorids: Western Indian Ocean to Western Pacific; mostly tropical, some temperate. Many distinctive colored species. Characterized by elongated bodies, with gills on elevated part of their backs, short/slender mantles (with foot behind it). Their chemo- and tactical-sensory apparatus (rhinophores) are almost always branching (foliaceous). Feed on bryozoans, ascidians, cnidarians, other nudibranchs... Genera Nembrotha, Roboastra, Tambja can be distinguished only by dissection: radula and sex organs in particular. Larger animals (up to 15 cm.) for nudi.s... use their narrow, extendable throats as a suction pump in feeding (rather than as a scraping radula)... easier than many nudi.s therefore to care for in captivity. Possible Aiptasia feeders.

Nembrotha cristata  N. Sulawesi (Lembah Strait)
