Symphurus atricauda is a species of tonguefish belonging to the family Cynoglossidae. Found throughout various marine environments, it exhibits distinctive features and plays a significant role in its ecological niche.

Description & Characteristics

Symphurus atricauda, commonly known as the black-tailed tonguefish, is a relatively small species, with a maximum recorded size of 21.0 cm. Its body is elongated and flattened, characteristic of the tonguefish family, with both eyes situated on the right side of its head. This adaptation allows the fish to lie flat on the seabed and effectively camouflage itself. The body is typically brown or gray, with a darker coloration towards the tail, hence the name “black-tailed”.

Habitat and Occurrence

Symphurus atricauda displays a remarkable depth range, occurring from 2.0 to 201.0 meters. This adaptability allows it to thrive in a variety of marine zones, from shallow coastal waters to deeper continental shelf environments. The species is commonly found on soft sediments like sand or mud, where it can effectively burrow and hide from predators.

Taxonomy

The species Symphurus atricauda belongs to the Class: Teleostei, Order: Pleuronectiformes, and Family: Cynoglossidae. Teleostei encompasses a vast and diverse group of ray-finned fishes, while Pleuronectiformes, commonly known as flatfishes, are characterized by their laterally compressed bodies and asymmetrical eyes. Cynoglossidae, the tonguefish family, comprises a diverse group of bottom-dwelling fishes, many of which are commercially important.

Feeding

Symphurus atricauda is a carnivorous species, primarily feeding on small invertebrates found on the seabed. Its diet likely consists of worms, crustaceans, and other benthic organisms. Using its sensitive barbels, the fish locates and captures its prey, playing a vital role in the food web of its marine habitat.
