Special anatomical, physiological
or behavioral adaptations:
These sharks are not endangered at the moment.
They tend to stay inshore near coral reefs and tidepools; however, they
have fallen prey to fisheries in India and Thailand.
Also interesting is the fact that the gills of
this shark are sometimes infested with the larva of isopods which is utilized
as food. (The spiracles may be an adaptation for bottom dwelling which
helps keep the sand out of the gills as the shark feeds).
These cat sharks have small "whiskers" which are
called barbels. These are sensory organs which hang from each nostril.
