Pinjalo (genus) explained

Pinjalo is a genus of marine ray-finned fish, snappers belonging to the family Lutjanidae. They are native to the Indian Ocean and the western Pacific Ocean

Taxonomy

Pinjalo was created as a monotypic genus by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker, it was a monotypic genus containing only Bleeker's Caesio pinjalo, which he had Species description described in 1850. A second species, P. lewisi was added in 1987. The generic name Pinjalo is derived from a Malay word for a fish pinialo. The genus is classified within the subfamily Lutjaninae.[1]

Species

The following two species are classified within the genus Pinjalo:

Characteristics

Pinjalo snappers are medium-sized snappers and have moderately deep bodies with a comparatively small heads and a pointed snout. The eyes are placed in the middle of each side of the head. They have small teeth in their jaws with no enlarged cacine like teeth. The vomerine teeth and the palatine teeth are tiny.

Pinjalo snappers are found in the tropical waters of the Indian Ocean and the Western Pacific Ocean. They can be found on reefs and rocky substrates as deep as around .[2]

Biology

Pinjalo snappers are predatory fish, feeding on benthic and planktonic invertebrates, and may also feed small fishes.[2] They may form large schools.[3]

Fisheries

Pinjalo snappers are important to artisanal fisheries in some parts of their range and are potentially exploitable more widely. They are mostly caught using handlines, traps and bottom trawls. The flesh is of considered to be of good quality and is usually sold fresh.[2]
