The dark green blood was oozing out of my
right index finger in a steady stream just as
I saw the 6 foot bull shark circling the small
reef to my right. No, this isn't an excerpt
from some macho outdoor magazine but the true
account of my first experience with the animal
we love to hate, the shark. It happened some
21 years ago, fresh out of High School, three
friends and I had decided to experience what
diving was all about and travel to the Bahamas.
We were all just rookies, having been
SCUBA-diving certified only a couple of years
and never having dove more that an hour away
from San Diego, let alone with sharks and
barracudas.
Carl, my diving buddy, had just handed me
a beautiful conch shell and I was happily
swimming with it about 70 feet down around
the edge of a magnificent coral outcropping,
scanning the sea floor for another. All of
a sudden I felt a sharp pain in the hand I
was toting the large pink shell in. Looking
down toward the conch I saw what was the largest
Hermit Crab I had ever seen taking aim at
another one of my fingers from inside the
relative safety of the shell. Even at that
age I knew better than to fight with large
armored crustaceans and dropped the prize
shell before the defensive Hermit could make
his second direct hit to my digits. But
unfortunately the damage had been done and
now I was the happy possessor of a 1/2 inch
long slice in my index finger. What made the
experience so eerie was that I was down so
deep that the short wave length of the color
red could not penetrate, even here in the
Bahamas and so I was watching what appeared
to be dark green blood seep from the cut.
It was at this time that I spotted the Bull shark! Wow, my
first shark, I thought. It was only miliseconds later that
I remembered
my leaking finger and quickly grabbed a tight hold upon it
to stop the bleeding. Here I was, miles from home, swimming
in warm tropical waters, beautiful sea shells littering the
ocean bottom and I'm bleeding like a stuck pig, as a large
(to me) potentially dangerous shark cruises by. If it wasn't
for bad luck I would have no luck at all. Every imaginable
scenario went racing through my mind. Would I be attacked?
Would my friends be attacked? Would the idiotic Divemaster
who had brought us to an ocean where sharks were to be found
get his just desserts? And finally, would I ever find another
conch shell so pretty again? Well, to my amazement the shark
paid little or no attention to me and my finger or anyone
else in my group and as suddenly as it had appeared it was
gone.
Since then I have been fortunate enough to
dive in many parts of the world with many
different types of sharks and I am still
find myself totally in awe of them, if not
better informed about them. Nearly 350 species
of sharks swim in the seas and Doheny and the
surrounding area have their share. I would like
to tell you folks a little about some of them.
Leopard Shark: This is one of the
most abundant sharks in our area as surf
fishermen will attest to. They are easily
identified by their gray color with large
dark spots or saddles across their backs. They
are not aggressive toward people and prefer
to dine on fish eggs sand dabs and shiner
perch. Leopard Sharks can grow up to seven
feet in length but rarely will you ever see
them even up to six feet.
Horn Shark: This lethargic fellow
prefers to prowl at night and can often be
found in the same cave or crevice for months
or years at a time. Horn Sharks have very
blunt, almost comical heads, are brown or
brownish gray with numerous small spots and
possess a spine in front of each dorsal fin.
This shark is on average about two feet in
length but can grow as long as three feet.
This is another harmless shark as it's diet
of sea urchins, worms, crabs and club anemones
can attest.
Brown Smoothhound: This three-foot shark is another
species that surf fishermen frequently catch and is characterized
by its light brown color and rear section of the two dorsal
fins which appear frayed. It prefers a sand or mud covered
ocean floor. Brown Smoothhounds can be found just offshore
and will often be found in schools. Their diet consists primarily
of shrimp and crabs.
Thresher Sharks: You just can't
confuse these sharks with any other local
shark because of the incredibly long upper
lobe of their tail fins. We have two species
of Thresher Sharks in Southern California,
the Common and the Bigeye Thresher. Colors
can vary from brown to blue to black and can
reach a length of 18 feet. Threshers are
usually found far offshore and are a favorite
catch of sport fisherman because of their
excellent tasting meat.
Mako Shark: This fast swimming
shark are some of the most impressive sharks
to catch because of their propensity to leap
out of the water as much as 20 feet. Makos
are very sleek with pointed snouts, dagger
like teeth and metallic blue coloring. Makos
feed on fast swimming school fish like
bonito, mackerel, tuna and even swordfish.
Thought to be the fastest swimming shark,
this species lives far offshore and can reach
lengths of 12 feet.
White Shark: No discussion on sharks
would be complete without mention of this
great beast. Reported to grow up to 25 feet
this large shark can sometimes be found in
surprisingly shallow water. It has been known
to attack divers, swimmers and bathers. While
Southern California does have some of these
sharks in its waters, as evidenced by the
recent attack off Point Loma, the major bulk
of the population lives off north central
California near Santa Cruz. The main reason
for this is that the White Shark's main food
source, marine mammals such as Elephant Seals,
are found in large numbers there.
Of course there are many other types of
sharks in Southern California, including
blue sharks, angel sharks, swell sharks,
basking sharks and a host of others. People
should realize that most sharks pose no
threat to man and play a vital role in the
ecology of the oceans. Many populations of
commercial sharks have been hunted to dangerous
levels for not only their meat but for souvenirs
as well. Until recently there was little or
no regulation on shark hunting and only time
will tell if these populations will recover.
With recent medical research on sharks showing
promise in such fields as cancer, we should
be protecting these splendid predators, not
wiping them off the face of the earth.
