Have survived 5 major extinctions – have lasted 100 times longer than man
Relatively unstudied - we still know very little about them
Increasingly important to tourism – millions of $
Biology incredibly unique
Keep our oceans healthy and bio-diverse
Have 7 highly evolved senses
Learn quickly & constantly adapting
Magnificent predators to be respected and revered.
Over 500 unique species
Whale sharks: the world ’ s largest fish feeds on plankton (50 feet)
Frilled sharks: one of the oldest and most unusual species
Angel sharks: hide in the sand and are bottom-feeders
Dwarf lanternshark: smallest shark (6 inches)
Great White: perhaps the most famous, and one of the few implicated in attacks on humans
Saw sharks: slender shark with saw-like snout that finds and slashes prey. Long ‘ barbel ’ s are electro-sensitive to find prey.
Sharks are critically important
Sharks are the apex predators of almost every ocean habitat
At the top of the food chain, sharks keep our oceans healthy
They have groomed other species for millions of years and keep them in check
Our oceans supply a major source of food and oxygen to us and remove carbon dioxide (global warming gas)
Should we fear sharks?
So why do we love to hate sharks?
Fear of the unknown – vicious, indiscriminate, unpredictable bloodthirsty predators
Media feeds us mis-truths building our fears
We LOVE our monsters!
Of 500 species – only 10 have been associated with the rare attacks on humans
Our irrational fear of sharks explains our lack of desire to conserve them.
Fiction Fact Fact
Sharks are facing extinction
We are witnessing the first round of ocean extinction
Our impact on the ocean in the last 50 years is devastating – pollution, overfishing, habitat destruction
90% of some shark species have been destroyed
Demand for shark is at an all time high – trade goes global – and underground
Even marine reserves are target of illegal fisheries
No species are internationally protected
Predators … ... Or Prey?
The numbers are haunting
Sharks are being chased to extinction because their fins are currently valuable
97 to 99% of regional populations of certain shark species are already gone
23% of all sharks species are endangered (World Conservation Union)
42% of Mediterranean shark species are endangered
Shark populations are plummeting
Why should we care?
The oceans are the most important ecosystem on the planet
That life is kept healthy by sharks: apex predators
The oceans - our life support systems - are being destroyed
We are threatening our own source of food and oxygen in an unprecedented way
We are (again!) running a large scale experiment on our planet without understanding the implications
We are killing sharks at an unsustainable rate
Sharkfinning: sharks’ greatest threat
Cruel practice of slicing off fins – then dumping fish
95% of fish is wasted – fin is most valuable
Millions of tons of shark fin harvested per year – and growing
Used as a tasteless ingredient in a social status soup
Demand continues to increase while supply plummets
World-wide problem fueled by greed
Indiscriminate practice: all ages, sex & species killed
Sharks are disappearing without us even noticing or caring
Shark fin soup driving demand
Shark fin soup is a sign of prosperity and respect in Asia
The vitality of the Chinese economy has driven demand for shark fin soup
Shark fin soup costs as much as $100 a bowl
Shark fins are surpassed in cost only by such foods as some caviar and truffles
Dried shark fins cost anywhere from $100 to $300 per pound
A single Whale Shark pectoral fin can sell for up to $15,000
The shark fin market alone causes upwards of 73 million shark deaths each year
Myths that kill sharks
MYTH: Sharks fin soup: a sign of prosperity
FACT: Prosperity only for the mafia-like trading firms
MYTH: Sharks fin soup tastes great
FACT: Shark fin has no taste
MYTH: Shark cartilage cures arthritis, cancer, HIV
FACT: Research indicates it is ineffective & shark products contain high concentrations of highly poisonous mercury
MYTH: Sharks don ’ t get sick
FACT: Sharks get cancer and tumors
Bycatch is a huge problem
Bycatch = in fishing, the unintended catch of species other than the ‘target’ species
An estimated 50 million sharks are caught as bycatch each year
Sharks are 25% of the total catch in the Australia long line tuna and billfish fishery and Fiji long line tuna fishery.
Sharks are 32% of the Hawaii-based long line swordfish catch.
Sharks are especially vulnerable
As apex predator, with few natural predators, sharks have evolved with a slow reproduction rate
Most species take years to reach sexual maturity (sometimes over 12 years)
They raise relatively few pups a year (sometimes only 2)
In contrast, bony fish reach sexual maturity in months & lay millions of eggs
No other fish is in as much danger of over-exploitation because of the value of shark fins
Highly migratory – yet none are protected internationally
People don ’ t care about them – media influence
Lack of data – we don ’ t know how big the problem is
Consumers are largely unaware of the issue – soup translates as “fish wing” in Chinese
Life without sharks?
Loss of the apex predator can un-cork havoc in the ocean environment
Sharks control countless populations of fish species, including other predators
Phytoplankton-feeding fish populations are likely to increase and consume more phytoplankton
Phytoplankton produces 50-70% of earth ’ s oxygen
More than all the trees and forests and jungles combined
What happens to us when our source of oxygen declines?
Loss of sharks will have unpredictable impact on our sea food
Recent regional reports indicate dramatic and undesirable effects of local destruction of sharks – collapse of the mid-Atlantic scallop fisheries and death of coral reefs in Belize
Changing the mindset … Changing our future.

“Nothing in life is to be feared. It is only to b more
“Nothing in life is to be feared. It is only to be understood.” – Marie Curie
Sharks are disappearing without us noticing or caring. They are facing extinction. Some species are over 90% extinct.
More than 100 million sharks are killed per year. There is no global protection of sharks – there is no where we can ensure sharks can escape the slaughter. And even in our protected areas, there aren’t enough resources to patrol and keep our sharks safe.
This is complicated by the fact that people don't know about the issue or don't care about sharks because they don't realize how amazing – and critical – they are. Sharks are consistently misrepresented in the media as bloodthirsty and insatiable enemies of mankind, inspiring irrational fear in every body of water. This irrational fear has resulted in a lack of sympathy or concern for what we believe to be an important and grand animal.
Sharks have been in the oceans for over 400 million years, forming the life that has evolved within the seas. As predators at the top of the food chain, they play a critical role in maintaining the health of the ocean ecosystem. We have already witnessed the complete collapse of mollusk fisheries in Chesapeake Bay and the death of much of the coral in Belize both due to the cascading domino effects when sharks were removed from those fragile ecosystems. There is no telling what far-reaching effects we may experience if we remove sharks from our oceans, but the thought terrifies me. The oceans are our life support system: they control our climate, they provide our food and they generate 70% of the oxygen we breathe and remove 70% of carbon dioxide – the global warming gas.
Sharks are prey – not predators. At this point, up to 90% of key shark species have been destroyed but the demand for is still at an all time high fueled by greed. Even our marine reserves are the target of illegal shark fisheries.
If we don’t act now, we are going to lose our sharks – and our oceans – our life support systems on this planet. Everyone needs to be aware of this situation – and everyone needs to join the fight. We can save our sharks by coming together in a grass roots movement and turning our passion into action.
