The warty slug, Peronia verruculata, is a species of air-breathing sea slug belonging to the family Onchidiidae. Despite its name, it is not a true slug but a shell-less marine gastropod mollusc. This species is adapted to intertidal zones, often inhabiting rocky shores, mangroves, and tide pools. Peronia verruculata is characterized by its warty, leathery body and ability to survive underwater and in exposed conditions during low tide. It breathes through specialized gill-like structures and uses a radula to graze on algae and detritus.
Distribution of Peronia verruculata
Peronia verruculata is widely distributed across tropical and subtropical regions. It is commonly found in the Indo-Pacific, including the Indian Ocean, Southeast Asia, northern Australia, and Pacific islands. The species thrives in warm, saline environments, especially in habitats with plenty of algae for food and crevices for shelter during tidal changes.
Human Use
Peronia verruculata has only occasional local uses. In some coastal communities, it is collected for traditional medical purposes and is often used in folk remedies.
In some coastal areas in the Philippines, these warty slugs are foraged for a quick and simple snack.
