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.^[2]

Classification

Intertidal sea slugs are gastropods belonging to the subclass Heterobranchia and the family Onchiididae. They share many characteristics of shell-less marine mollusks, including dorsal gills that are visible when relaxed and retracted when crawling during low tide.^[2]

Distribution and habitat

This species has a cosmopolitan distribution across the entire tropical and subtropical Indo-West Pacific, from South Africa to Hawaii. It prefers the rocky intertidal area, stays hidden in crevices such as the lagoon during high tide, and only comes out during low tide.^[2]

Description

Peronia platei has a body that isn't flattened and is grey colored with small rounded protrusions on the exterior surface. It has black dorsal eyes at the tip and gills present under the dorsal notum.^[2]Peronia platei has gills on its back (dorsal notum) and 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 that is 5 mm long; the spine of the accessory penial gland is 0.9 mm long, narrow, elongated, straight, or slightly curved. The specimen has intestinal loops of type V and several dorsal papillae with eyes and rachidian and innermost lateral teeth. They breathe air using their gills and die if exposed to water for too long.^[2] The color of the dorsal notum is dark grey, including papillae; some papillae show black dorsal eyes at their tip, and the number of papillae with dorsal eyes varies (from 7 to 10). Its mantle (hyponotum) is light yellow, and the foot is pale yellow to orange. The ocular tentacles are grey, like the head.^[2]

Human use

This species is being used to study anatomical and systematic descriptions for future research. It is an indicator species that give clues about the health of the oceanic environment.^[3]

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.
