“We must not only defend sharks because they are useful and beautiful, but we must protect the sea that feeds them. And also restore the balance of the great ocean’s ecosystem, of which sharks form an important link and on which we ultimately depend.”

Requins, Innocents sauvages, J-Y Cousteau et Yves Paccalet, Ed. Robert Laffont 1997.

“If you talk to animals they will talk with you and you will know each other. If you do not talk to them, you will not know them and what you do not know you will fear. What one fears, one destroys.”

Ban the cruelty of finning of sharks
Maligned and misunderstood, sharks are species at risk who need our help to survive. Subjected to overexploitation for the Asian food market, the cruel method of finning leaves sharks alive, with their fins removed, sinking to death unable to swim.

Sharks ~ Their True Nature

SHARK FACTS

  • As top predators of the seas, sharks play a key role in the health of marine ecosystems.
  • Sharks grow and mature slowly. Some incubate their young for more than two years, the longest gestation period of any vertebrate. All this makes them highly vulnerable.
  • Sharks are wary of people and most will swim away.
  • Shark pups are born with large livers for survival. This discovery shows how sharks evolved to ensure their brood’s survival. Read more here.
