Common bluestripe snapper

The common bluestripe snapper (Lutjanus kasmira), bluestripe snapper, bluebanded snapper, bluestripe sea perch, fourline snapper, blue-line snapper or moonlighter, is a species of snapper belonging to the family Lutjanidae. It is native to the Indian Ocean from the coast of Africa and the Red Sea to the central Pacific Ocean. It is commercially important and sought as a game fish. It can also be found in the aquarium trade.

Distribution

The bluestripe snapper is one of the most widespread species of the Lutjanidae, ranging from the coast of Egypt bordering the Red Sea, south to Madagascar and east to India, China, Southeast Asia, Australia, and a number of Pacific islands.

Like many snappers, it inhabits coral reefs, occurring in both shallow lagoons and on outer reef slopes to depths of at least 60 m (200 ft), at depths reaching 180 m (590 ft) at the Marquesas Islands and 265 m (869 ft) in the Red Sea. In Hawaii, they spend some time over seagrasses and sandy substrates. They frequently gather in large aggregations around coral formations, caves, or wrecks during daylight hours.

The preferred habitat of the species changes with age, with young fish schooling on sandy substrates, while larger fish are more solitary, and inhabit deep reefs.

Behaviour

The bluestripe snapper has a varied diet, feeding on fishes, shrimp, crabs, stomatopods, cephalopods and planktonic crustaceans, as well as plant and algal materials. Diets vary with age, location, and the prevalent prey items available locally.
