Spotted Cusk-eel, Chilara taylori
The Spotted Cusk-eel, Chilara taylori, whose common Spanish name is Congriperla Moteada is a member of the Cusk-eel or Ophidiidae Family, known collectively as “Brótulas and Congriperlass” in Mexico.
The Spotted Cusk-eels have elongated compressed bodies that taper to a point at the rear – a top scientist even described them as resembling a letter opener. They are a uniform creamy brown color and their head and body are covered with large dark spots that form three or four rows along the body. Their anal and dorsal fins have black margins. Their head and overhanging snout are rounded and their mouth and eyes are medium-sized. Their anal and dorsal fin bases are long and continuous with their pointed caudal fin; the dorsal fin is longer and originates before the anal fin. Their pelvic fins each have a pair of small threads of unequal length inserted under the eyes. They lack the strong snout spine that is found in most other Cusk-eels. Their body is covered with small round scales.
The Spotted Cusk-eels inhabit sandy and muddy bottoms and are found demersal in burrows they enter into tail first, at depths up to 2,400 feet. They reach a maximum length of 40 cm (15.9 inches). They hide in caves during the daytime and only emerge at night to feed on crustaceans, polychaete worms, small clams, and other invertebrates. In turn, they are preyed upon by gulls, porpoises, and seals. They have a limited distribution being found along the west coast of Baja from Tijuana to Todos Santos with this southern range established by the fish pictured below. Fossil remains of the Spotted Cusk-eels were found in Southern California indicative that this species has been present since the Pliocene Epoch (1.8 to 5.3 million years ago).
The Spotted Cusk-eels are most easily confused with the Leopard Cusk-eel, Lepophidium pardale (large black blotches) and the Spotfin Cusk-eel, Ophidion galeoides (broken brown stripe along lateral line; dark blotch at front of dorsal fin). They are obtained as a by-catch of deep water trawlers and by hook and line by commercial fishermen in the greater Los Cabos area, but are too rare and too small to be of commercial interest. They are seldom seen by humans and are of limited interest to most.
