SHARKS
 Common
Name: Horn Shark
Genus
and Species: Heterodontus francisci
Phylum: Chordata
Class:
Chondrichthyes
Distinctive
Features:
The
horn shark rarely grows larger than two feet. They are tan to dark grey
in color with numerous black spots with dark brown rims around the spots.
Above each eye are large eye brow ridges. The front of the shark face is
squared off and conceals its many small teeth which are adept at crushing
their prey.
Behavior:
These sharks are common bottom dwellers off of our coast. The design of
their body allows them to sit quite comfortably on the bottom, however this
design makes them slow swimmers. When approached by divers these fish
will stay stationary on the bottom or will swim short distances to avoid the
confrontation. If molested the horn shark will use the two spikes, one of
which is pictured to your right, in front of the two dorsal fins to make
touching or an attempt for predators to eat this shark
a very unpleasant experience.
Habitat:
These fish can be found at the top of the kelp canopy all the way down to the
bottom of the sea floor to depths of up to 60 feet. As discussed above
these fish are quite shy in nature but in reserves can by quite unafraid if not
almost aggressive.
Diet:
Horn sharks consume urchins, small crabs, and some shell fish. These
sharks pose no threat to humans as man eaters, however if molested the spikes
in front of the dorsal fins can inflict significant harm.
Fun
Facts:
Garuanteed
to see: Horn sharks may be located all up and
down our coast. However their numbers are not so high that we can guarantee you
will find the horn shark at any one location. Some beaches where it is
possible to see a horn shark include:
Point Dume,
Deer Creek, &
La Jolla Cove.
