Brachirus niger, commonly known as the Black Tongue Sole, is a species of flatfish belonging to the Soleidae family. It is a relatively small species, typically reaching a maximum size of 35.0 cm.
Description & Characteristics
Brachirus niger is a flatfish with a characteristic flattened body shape, typical of the Pleuronectiformes order. The eyes are positioned on the right side of the body, which lies uppermost, and the left side is pigmented. This allows the fish to camouflage effectively against the seabed, making them difficult to spot by predators and prey.
Habitat and Occurrence
Brachirus niger is a demersal fish, meaning it inhabits the seabed. It is found in the tropical waters of the Indo-Pacific region. This species is primarily found in the neritic zone, which is the coastal area of the ocean extending from the shoreline to the edge of the continental shelf. Brachirus niger can be observed at depths ranging from shallow waters to around 100 meters.
Taxonomy
Brachirus niger is classified within the Class: Teleostei, Order: Pleuronectiformes, and Family: Soleidae. These classifications reflect the unique characteristics of the species, including its flattened body, its eyes on one side of its body, and its solitary, bottom-dwelling lifestyle.
Feeding
Brachirus niger is a carnivorous fish that feeds primarily on invertebrates found on the seabed. It uses its sensitive barbels, located near its mouth, to detect and locate prey. The Black Tongue Sole ambushes its prey, capturing it with a swift bite. This feeding strategy is typical of other soleid species and reflects their adaptations to life on the seabed.
