Who is it?

Genus Scolopsis

In 2023, the genus Scolopsis comprises 18 species recorded in the tropical and subtropical regions of the Indian and Pacific Oceans. These fish, often referred to as "Scolopsis" generically, display a variety of appearances and habitats.

Scolopsis are opportunistic predators that primarily feed on benthic invertebrates (polychaetes, brittle stars, aquatic worms, and small crustaceans). Juvenile fish feed during the day, while adults exhibit nocturnal habits and primarily hunt at night. During the day, adults hide, venturing out to forage above sandy banks.

Their body shape is oval, with several species featuring a diagonal band that separates the typically white belly from the patterns on the upper part of their bodies.

Different species of Scolopsis occupy a range of habitats, from mangroves to coral reefs. Some are found in shallow waters near coastlines, while others prefer deeper reef areas.

Many Scolopsis species are categorized as protogynous hermaphrodites, meaning they are born as females and can transition to males as they grow. However, there are variations and exceptions to this pattern, and not all females necessarily change their sex.

As of now, none of the Scolopsis species are considered threatened. Although Scolopsis bilineata occasionally appears in small numbers at local fish markets, there is no targeted fishery for them. Live specimens are sometimes captured for the aquarium trade.
