Biology
Oviparous, paired eggs are laid. Embryos feed solely on yolk [733]. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother [17086]. From the work of Libby and Gilbert (1960) (Ref. 51117) and Luer and Gilbert (1985) (Ref. 38742) male and female clearnose skates mate side by side in an upright position (Ref. 49562). Actual copulation occurs when the male bites the caudal margin of the female"quot;s pectoral, bends his tail 75 degrees beneath hers and inserts one clasper, flexed ("quot;splayed"quot;) medially 90 degrees, into her oviduct (Ref. 49562). A female displays "quot;back arching"quot; and "quot;pectoral fin undulations"quot; as precopulatory behavior to attract males (Ref. 49562). Inhabits inshore areas. Prefers waters of 10°-21°C. Feeds mainly on decapod crustaceans, bivalves, polychaetes, squids and fishes.
