The Xenocongrid Eel Chlopsis Bicolor in the Western North Atlantic
Two females and one male of the xenocongrid eel, Chiopsis bicolor Rafinesque, were collected from moderate depths by Miami scientists working in the Florida Straits. C. bicolor was previously known only from the Mediterranean Sea (and, except for the larvae) in the vicinity of the Messina Straits. The known western Atlantic range of C. bicolor is in the Florida Straits from Key Largo to the Marquesas, but a broad western Atlantic distribution is anticipated. The pigmentation, morphometry, sensory canals, and dentition of the western Atlantic material is compared with two specimens of C. bicolor from Messina Straits. The body's outline and pigmentation, and the dentition of the Florida C. bicolor are figured. The osteology of C. bicolor and another xenocongrid eel, Kaupichthys atlanticus, were studied and compared with earlier studies of C. bicolor and K. diodontus. The bones of the jaws and the suspensorium, the opercular series, branchiostegal rays, hyoid bones, pectoral girdle, neurocranium, and caudal skeleton of C. bicolor and K. atlanticus are described and figured.
