Bathygobius brasiliensis, commonly known as the Brazilian goby, is a small, non-migratory fish species belonging to the Gobiidae family. It is distinguished by its unique physical characteristics and plays a vital role in its coastal marine environment.
Description & Characteristics
Bathygobius brasiliensis is a relatively small goby, reaching a maximum size of 8.1 cm. This species exhibits a slender body shape and is characterized by its distinctive coloration.
Habitat and Occurrence
Bathygobius brasiliensis is a demersal fish, typically found in shallow coastal waters, ranging from 1.0 to 3.0 meters in depth. It is a common inhabitant of the neritic zone, a marine environment characterized by relatively shallow waters that extend from the shoreline to the edge of the continental shelf. This species is particularly well-suited to the diverse and dynamic environments of the neritic zone, where it finds ample food sources and suitable habitats for breeding and shelter.
Taxonomy
Bathygobius brasiliensis belongs to the Class: Teleostei, Order: Gobiiformes, and Family: Gobiidae. The Gobiiformes, or goby, order encompasses a wide variety of fish species known for their small size, benthic (bottom-dwelling) habits, and the presence of a fused pelvic fin that forms a suction disc, allowing them to attach themselves to surfaces. The Gobiidae family, to which Bathygobius brasiliensis belongs, is one of the largest and most diverse fish families, containing over 2,000 species found worldwide.
Feeding
Bathygobius brasiliensis is primarily a carnivore, feeding on small invertebrates such as crustaceans, worms, and insect larvae. Its diet is crucial to the balance of its marine ecosystem, as it helps to control populations of these small organisms.
