Habitat and Occurrence

Anguilla obscura is primarily found in the western Atlantic Ocean, with a distribution that extends from the Caribbean Sea to the Gulf of Mexico. They are particularly common in coastal waters, including estuaries, lagoons, and rivers. This species prefers habitats with soft, muddy bottoms, where they can burrow and hide from predators.

Taxonomy

Anguilla obscura is a member of the family Anguillidae, which includes a diverse array of eels. It belongs to the order Anguilliformes, a group of fish characterized by their elongated bodies and lack of pelvic fins. They are classified within the Class Teleostei, a vast group of ray-finned fishes, representing the most diverse class of vertebrates.

Feeding

Anguilla obscura are carnivorous fish, feeding primarily on a diet of small fish, crustaceans, and other invertebrates. Their diet varies depending on the availability of prey in their specific habitat. They are opportunistic feeders and use their keen sense of smell to locate potential food sources.
