Onchidiidae are a family of small, air-breathing sea slugs. They are shell-less marine pulmonate gastropod molluscs. Onchidiidae is the only family within the superfamily Onchidioidea.
Onchidium stuxbergi is a species of air-breathing sea slug, a shell-less brackish water pulmonate gastropod mollusk in the family Onchidiidae.
Onchidium griseofuscum is regarded as a nomen dubium.
Onchidium reevesii is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae. It is one of four recognized species in the genus Onchidium.
Onchidium lixii was described as a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae. However, the name is considered a nomen dubium.
Scaphis punctata is a synonym of Peronia peronii, a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae.
Onchidium typhae is a species of air-breathing sea slug, a shell-less brackish water pulmonate gastropod mollusk in the family Onchidiidae.
Peronia indica is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae.
Onchidina is a monotypic genus of air-breathing sea slugs, a shell-less marine pulmonate gastropod mollusks in the family Onchidiidae. Its sole member is the species Onchidina australis. Uniquely within the Onchidiidae, O. australis lives above the tidal zone in a fully terrestrial habitat.
Peronia is a genus of air-breathing sea slugs, a shell-less marine pulmonate gastropod mollusks in the family Onchidiidae. These slugs differ from other onchidiid slugs in having branched "gills" on their dorsal side, although these can be retracted. More than two dozen species of Peronia have been described from the Indo-West Pacific, but a recent revision of the genus determined that 21 of these names are synonyms. Nine species of Peronia are recognized, most of which can differentiated only by examining their internal anatomy or with DNA sequencing.
Peronina is a genus of air-breathing sea slugs, a shell-less marine pulmonate gastropod mollusks in the family Onchidiidae.
Platevindex is a genus of air-breathing sea slugs, a shell-less marine pulmonate gastropod mollusks in the family Onchidiidae.
Platevindex luteus is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae.
Paromoionchis is a genus of air-breathing sea slugs, shell-less marine pulmonate gastropod mollusks in the family Onchidiidae. Most Paromoionchis species live on the mud in mangrove forests in the Indo-West Pacific.
Paromoionchis tumidus is a species of small, air-breathing sea slug, a shell-less marine pulmonate gastropod mollusc in the family Onchidiidae.
Platevindex burnupi is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae.
Platevindex tigrinus is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae.
Wallaconchis is a genus of air-breathing sea slugs, a shell-less marine pulmonate gastropod mollusks in the family Onchidiidae.
Wallaconchis graniferus is a species of air-breathing sea slug, a shell-less marine pulmonate gastropod mollusk in the family Onchidiidae.
Peronia platei is a species of slug, a marine gastropod mollusk in the family Onchidiidae, one of the families of sea slugs. Nine species of Peronia are recognized; the way to tell them apart is by DNA sequencing by mitochondrial and nuclear sequence or checking their internal anatomy. This species has hermaphroditic parts in the posterior regions of the deferent duct and straight oviduct. The male part is the muscular sac of the accessory penial gland in the anterior area. It is distributed across the entire tropical and subtropical Indo-West Pacific, from South Africa to Hawaii.
