The Brown Catshark is a small animal with a soft, slender body. Unlike many other sharks, it has a delicate skin that can be easily damaged. Little is known about this species, although they are thought to be a solitary and nocturnal species. Like other sharks, they seem to have the ability to sense electrical fields originating from other animals and undersea landforms. This special adaptation seems to aids the animal in both hunting and navigation. They prey on shrimp, squid and small fish.
The Brown Catshark can be found from the waters of British Columbia south to Baja, Mexico. It prefers to hunt along the muddy ocean bottom at the edge of the continental shelf.
Little is known about the numbers of this shark, but they are not currently listed as threatened or vulnerable.
