Description

The Japanese sawshark is a sawshark (Pristiophoridae) from coastal waters of the northwest Pacific, off East Asia. The species grows to about 1.4 metres and has a slender, grey-brown body and a long, flat, sword-shaped snout set with alternating large and small teeth, with a pair of long barbels halfway along it. As a bottom-dweller it sweeps the saw snout through sand and mud bottoms to injure or detect small fish and crustaceans. The toothed snout can give cuts when handled.
