Tete Sea Catfish

Descrição

Ariopsis seemanni, commonly known as the Tete Sea Catfish, is a species of marine and brackish water catfish belonging to the family Ariidae. It is characterized by its shark-like appearance, particularly when juvenile, with a sleek body and prominent dorsal and pectoral fins. This species is often encountered in coastal waters, estuaries, and mangrove habitats, and is known for its adaptability to varying salinities. While juveniles are popular in the aquarium trade, adults can reach a considerable size and are important components of their native ecosystems.
