Black Snapper

The black and white snapper (Macolor niger), also known as the black and white seaperch or black snapper, is a marine ray-finned fish belonging to the family Lutjanidae. This species is indigenous to the 🌊 Indian Ocean and the western 🌊 Pacific Ocean.

The species was first formally described in 1775 by the Swedish-speaking, Finnish-born explorer and naturalist Peter Forsskål, who named it Sciaena nigra, with the type locality recorded as Jeddah. The specific epithet "niger" is derived from the Latin word for "black," referencing the predominately black coloration of adult specimens. In 1860, the genus Macolor was described by Pieter Bleeker, a Dutch physician and ichthyologist, who redundantly renamed Cuvier’s Diacope macolor as Macolor typus.

Morphologically, the black and white snapper exhibits a relatively deep body. It features a convex dorsal head profile and a substantial mouth that extends back to the eye. The jaws are equipped with an outer band of conical teeth, which transition into canine-like teeth anteriorly, complemented by bands of bristle-like teeth. Vomerine teeth are organized into a rough chevron without a median posterior extension. A distinct deep incision marks the lower margin of the preoperculum. The dorsal fin is armed with 10 spines and 13–15 soft rays, while the anal fin comprises 3 spines and 10–11 soft rays. Both dorsal and anal fins possess distinctly pointed rear tips. The pectoral fins are elongated, stretching to the anus, consisting of 17–18 fin rays, and the caudal fin is emarginate. The black and white snapper can attain a maximum length of 75 cm (30 in), although most individuals measure around 35 cm (14 in). Fins and eyes are black, with body color varying from light grey to black contingent on age. Juvenile individuals are typically striped, adopting a black modality in adulthood.

The species exhibits a broad Indo-Pacific distribution, from the eastern African coastline, including the 🌊 Red Sea, to 🇿🇦 South Africa, the 🇸🇨 Seychelles, and the 🌊 Indian Ocean islands such as the 🇲🇻 Maldives. Its range extends eastward to encompass regions like the Pacific's 🇲🇭 Marshall Islands, 🇼🇸 Samoa, and 🇹🇴 Tonga, south to 🇦🇺 Australia, and north to central 🇯🇵 Japan, with additional presences noted in Niue and the 🇨🇰 Cook Islands. It inhabits depths of 2 to 90 meters (approximately 7 to 295 feet), prominently around the outer slopes of lagoon reefs, channels, and seaward slopes.

As juveniles, black and white snappers are solitary, yet adults frequently form large schools. It is a predatory species, primarily consuming fish and crustaceans. The species participates in spawning aggregations and is often confused with the closely related midnight snapper (M. macularis), with which it sometimes forms mixed groups.

Highly valued as a food fish, the black and white snapper is targeted both commercially and recreationally. Additionally, it is present in the aquarium trade.
