Oahu plongée – Découvrir la plongée sous marine – première fois plongée Hawaii – baptême Oahu plongée sous-marine.
We get this question
all the time. "Are there any sharks where we will be diving?" The truthful
answer is yes there
are sharks. In all honestly you most likely will not see sharks
right away. Here is why. Sharks in Hawaii
are extremely shy when it comes to scuba divers. Most sharks in Hawaii would rather avoid you
at all costs.
You must understand that sharks brains are not wired to incorporate
eating human
beings, the sound of the scuba bubbles also play an important
reason why sharks in Oahu stay clear of divers.. Look at it this way. When did recreational diving really start ? Lets just say it was back in the
70s. So for the last 30 or 40 years sharks may have seen human
beings.
t of time
doesn't stand up to the time when the shark started to evolve, we are talking
dinosaurs times here.
Furthermore when scuba
diving around sharks I have personally noticed how sensitive the
sharks are to the sound of of scuba units- that is the sound of the
bubbles when you exhale. I have seen numerous times sharks actually
turn the other way once I exhale. As an underwater photographer
while diving in Hawaii it
is important to breath slowly to maximize your underwater experience
but the biggest reason why is to not scare off the marine life-
sharks. Once you fully exhale the sharks will leave. So you can't
hold your breath for 30 minutes. What do you do ? Well just breath
breath slowly or use what is called a rebreather. Rebreathers are
able to reuse the oxygen left unused in each exhaled breath while they
simultaneously remove C02 with a chemical which "traps" the C02.
The result is greatly extended dive with relatively small tanks. But
the best part of a rebreather is the fact that hardly any bubbles
are produced.
Great for underwater photographers. Honestly speaking, rebreathers are
expensive. About $5000 plus, so lets just stick with a typical scuba
diving set up, the traditional type.
Scared of sharks in Hawaii ? Watch video below!
So what kinds of sharks might we see when diving in Hawaii ?
Wait, better yet what kinds of sharks can we see in Oahu ?
The shark
that is mostly seen in Oahu and I think I can speak for the rest of
the Hawaiian islands is the whitetip reef shark. The white tip reef sharks are commonly seen
around the islands of Hawaii. Mostly during the day these reef
sharks find a nice dark cave, shipwreck, wreck or crevice and sleep.
Saving their energy for the evening hunt. So while we are diving I
am always looking underneath reef ledges and into small caves so we
can introduce of scuba diving guests to these amazing animals.
Whitetip reef sharks will not attack scuba divers. I think you would
have to physically hold a whitetip reef shark down then stick your
hands in their mouths to get bit. This is not to say whitetip reef
sharks are not dangerous. At night whitetip reef sharks hunt in
packs and are the reef's most extreme hunting machines. Preferring
to scare small fishes and octopus out of their sleeping holes on the
reefs.
Galapagos sharks are too commonly seen in the waters of Hawaii.
These sharks are seldom seen in shallow reef areas of Oahu and tend
to prefer deeper waters. I have seen Galapagos sharks in 50 feet of
water on a few reefs but the majority of the time we see these
sharks on wall and deep dives. (Galapagos sharks do resemble gray
reef sharks so my sighting could have been a gray.)Sure these sharks can be dangerous
weighing in up to 400 pounds. There have been attacks on people but
not scuba divers. Honestly I have never heard about this shark
attacking people but from other friends and dive friends I
have heard these sharks can be dangerous. Again, theses sharks too
tend to stay away from scuba divers. Scalloped Hammerhead Sharks, we've all seen them and love their unique
shape. Hammerhead sharks can get pretty big too. Some
species can
actually grow up to 20 feet. It is highly unlikely you will
encounter a
hammerhead shark on the reefs in Oahu. Although hammerhead
sharks do breed and call the Hawaiian archipelago their home scuba
divers don't really get to see these mysterious sharks often.
I personally
had the rare opportunity to see a rather large hammerhead once.
Believe it or not it was at Turtle
Canyons Waikiki in a depth of 30 feet."So Erik where is the
pictures?" Well believe it or not I couldn't get a good pictures
because the shark was moving so fast and the visibility was not the
best that day so my camera at the time couldn't focus on the shark
well. Really that is the truth...stop it !
What about tiger sharks? Yes tiger sharks in Hawaii can be
dangerous. As a matter of fact they are dangerous...in certain
settings and circumstances of course. The bad boy tiger sharks are very big and can grow up to 20 feet in
length and weight over a thousand pounds. Most of the tiger sharks
we see in Hawaii are juveniles that are around 6 to 8 feet.
The picture you see is of a juvenile tiger shark, very predominant
stripes and if you look closely you can see a fishing line and hook
in his mouth was taken at Turtle
Canyons in 30 feet of water. Encounters we had with tiger sharks were very fun leaving the
customer to question, "Are these sharks really dangerous ?" Due to
the fact that once the tiger sharks seen us it immediately swam in
the opposite direction. Every single time. I feel extremely comfortable if not more
curious about tiger sharks than any other shark in the waters of
Hawaii. Chance of seeing a tiger shark in Hawaii ? I'd say not
likely, I see tiger sharks about once every 2 months or so.
Occasionally people get the rare opportunity to see
tiger sharks
feeding on dead turtles from the boat.
Sandbar sharks in Hawaii. These sharks are pretty cool. Mostly small around 4 to 6 feet these interesting sharks with their pointy dorsal fin tend to stay in deep water. I have never seen these sharks in shallow water, reefs or wrecks. There are places on the North Shore, primarily where the shark tours and shark feeding goes on where you can see the sandbar shark. We have on a bunch of occasions went out to these areas, a few mile out and jumped into the water. These sharks at first are curious and will approach you, then they realize that there isn't not any food. They seem to associate boat engines with food. But then again, once theses sharks realized we had no food they just went away. When diving in Hawaii people must understand how important sharks' role plays on the reefs. Sharks are responsible for keeping the reef clean. In other words, sharks eat the sick and dying fish. Simple logic says if you take the sharks away there will be a sick reef which will have a trickle- down effect to even us, since we do eat fish. Without the sharks Mother Nature would not be able to survive. Sure there are other species of sharks that are found in Oahu and the Hawaiian archipelago but I really am getting bored of typing. Sharks are one of the neatest fish on the reefs, if you are lucky enough to see a shark while diving with Oahu Diving consider that a privilege- you will never forget it. If you have any questions or comments please let us know. We would love to hear from you.
