Filetail Catshark (Parmaturus xaniurus)
The filetail catshark gets its common name from the toothlike projections on its skin. Catsharks in general are relatively small, usually 12 to 39 inches long (30-100 cm), with flat heads and long, catlike eyes. Their teeth are very small and they have several rows of teeth in each jaw.
When a light shines on a catshark’s eyes, they glow—much like a cat’s eyes do. That’s because cats and sharks have special light-sensitive eyes designed for hunting in near-darkness. A catshark is always on the prowl. When a fish or squid swims nearby, the catshark lunges with its mouth wide open—and makes a quick meal of its prey.
