features
Notacanthus species are 0.2 to 1.20 meters long. They have an eel-like long but laterally flattened body. Only 6 to 15 individual fin spines are formed from the dorsal fin. Dorsal soft rays are not present. Their mouth is subordinate and of normal size, the maxillary is edentulous, the premaxillary and lower jaw are dentate. The number of Branchiostegal rays is 6 to 13, the gill trap is well developed. Cleithrum and Supracleithrum (two cover bones in the shoulder girdle) are heavily ossified.
