Do
the tags hurt?
This is a legitimate concern and something we have
also struggled with. However, when we think of what is at stake
- entire species that have existed for 400 million years, and
we consider the important information that each tag provides
- identifying their critical habitats for protection, we believe
that it is necessary sacrifice. In the last 40 years their
numbers have plummeted due to over fishing (some species are
90% depleted!!). As top predators for so many millions of years
they have adapted a life history that "self-regulates" their
own populations - slow reproduction. Therefore, they cannot
sustain the additional mortality that humans inflict. We realize
that everyone might not agree. But it is a decision that we
have made, and something that we certainly do not take lightly.
However, some facts about sharks are reassuring. Sharks generally
heal very quickly from wounds relative to other animals. Also,
they are tough. During the mating season we often see large
cuts on their backs and dorsal fins, where they give each other
"love bites". To us they seem like very deep cuts, but in a
matter of week they appear much less so. And a month or so
after mating season, virtually no traces of the bites remain
(no scarring). In comparison, the small dart that we insert
below the skin seems like a tiny splinter.
Are sharks dangerous to humans?
Unfortunately, sharks have been given a very bad reputation.
In reality, there are over 400 different shark species in our
oceans of which very few (such as the bull shark, great white
shark, and tiger shark) can be potentially dangerous to humans.
The likelihood of being attacked by a shark is less than being
hit by lightening. The average number of shark attacks worldwide
is approximately 50 per year with the majority being non-fatal
attacks. If you want to learn more about shark attacks and
behaviors, go to www.flmnh.ufl.edu/fish/sharks/isaf/isaf.htm
How can I protect myself against shark attacks or accidents?
The best way to protect yourself against a shark is
to study the behavior and gain as much knowledge and experience
with sharks as possible. It will soon become apparent that
sharks prefer to avoid humans. Many of the Adoptashark.com
members are experienced scuba divers and have spent hours in
the water with sharks. They suggest the following:
1. Avoid swimming, surfing or surface activitie in close proximity
to seals or sea lions in areas where great white sharks are
known to roam. There is a small chance you could be mistaken
for food by the great white.
2. Do not enter the water if you have an open wound.
3. When we enter the water we are sharing the ocean with animals
that make it their home. Always apply common sense and most
importantly, respect the shark like you would any other animal
in the wild.
What is the role of sharks in the ocean?
Sharks play an important roles in the marine ecosystem. As
top-level predators, they help control many fish and marine
mammal populations. By eating the weak or diseased animals
they help keep the ecosystem healthy.
How are sharks and rays different from fish?
Sharks have a lot of structural similarities to other
fishes. However, there are some significant differences as
well. The biggest difference is that while fishes have bony
skeletons, sharks have skeletons made mostly of cartilage.
Shark fins are usually thicker and stiffer and lack the spines
of bony fish fins. The gills of sharks are visible externally
while those of most bony fish are covered by a bony plate,
called an operculum or gill cover. Finally, while fishes are
covered by scales, sharks' skins are covered by dermal denticles,
a layer of tiny "teeth."
What can I do to help shark conservation?
If you have donated to this program, you have already
taken your first step towards participating in shark conservation.
We need your help to be able to do this important work and
we are very grateful for your support.
The first step towards achieving change is through educating
yourself and others about sharks, their conservation status
and the importance of their survival in the ocean. You can
help by avoiding eating or using shark products, such as shark
cartillage pills, shark meat, shark liver oil, and shark fin
soup. Research sea food sources to make sure you are supporting
sustainable fisheries.
Finally write to you government representatives and urge them
to support and prioritize ocean conservation and the creation
of marine protected areas. Our ocean resources are finite and
we must act now to ensure that our children and grand children
enjoy them as well.
Looking at the not too distant past, just a few generations,
we can see where a terrible mistake was made. In Europe and
the Americas, all the big predators, the bear, the wolf and
the lion, were hunted to near extinction. The idea back then
was, "The only good bear is a dead bear."
Our generation cannot afford to make the same mistake with
the great predators of the sea. Don't let the massacre of sharks
continue because it happens out of our sight or to animals
some of us may be afraid of. We make decisions every day. Make
a decision today to help sharks, help the ocean and help yourself.
If you have a question about sharks, rays or our work, please
email us and we may post it on our website.
