Echidna catenata

Echidna catenata is a species belonging to the order Anguilliformes in the family Muraenidae and genus Echidna. This species of eel inhabits the waters of the western Atlantic Ocean (from Bermuda, Florida and Bahamas to the West Indies and Brazil), as well as in the eastern Atlantic Ocean from Angola to the Cape Verde Islands. It inhabits rocky and/or sandy areas up to 20 meters deep.

The body of Echidna catenata is characteristic of an Anguilliformes, that is to say elongated, slightly flattened laterally and with a continuous dorsal fin that joins the anal fin at the end of the tail. The maximum length of this species is 160 cm, although specimens of 60-70 cm in length are usually observed. The head ends in a relatively rounded snout. It lacks pectoral and ventral fins, as well as scales covering its body. Instead of scales, Echidna catenata secretes a mucus that gives them protection and makes them very slippery. The body color is usually dark brown or blackish with yellowish interconnected spots.

During the day, we find the specimens of Echidna catenata hiding in holes in the rocks, and it is during the night when they come out of their dens in search of their prey, crustaceans and small fish. The teeth in its mouth, which are relatively blunt, are adapted to feed on crustaceans, crushing their shells without any problem.
