A particularly small, slender and distinctive shark, the crocodile shark is named for its prominent, spike-like teeth, and its habit of snapping vigorously when removed from the water. The spindle-shaped body is grey-brown above, sometimes with white or black blotches, and lighter on the underside, with white margins on the fins. The head is relatively short, with a pointed snout, protrusable jaws, long gill slits, and huge eyes, which lack nictitating membranes. The dorsal fin and pectoral fins are small and spineless, and the tail fin is asymmetrical, with a long upper lobe.
