Longnose sawshark (Pristiophorus cirratus) also known as the common sawshark is a sawshark of the family Pristiophoridae. This shark is large and stocky for a saw shark. It also has a very long rostrum, which can take up to 30% of its total body length. The longnose sawshark has pale yellow or grayish-brown dorsal coloring and white ventral coloring. Variegated, sometimes faint dark blotches, spots, and bars cover its back. The barbels of the longnose sawshark are halfway down the rostrum, but slightly closer to the rostral tip than the nostrils. Its maximum length is up to 1.37 m (4 ft 6 in). Order: Pristiophoriformes, Family: Pristiophoridae. |
