SHARKS DO NOT EAT PEOPLE!

  • Most sharks bite humans out of curiosity, not for a meal.
  • Sharks attack 50-70 people a year, which is less than those killed by Elephants, Bees, and Crocodiles.
  • Sharks have a low reproductive rate, they take a longer to mature, and they are long-lived

Ecological value of Sharks

  • Manage the population of fish
  • Genetic health of fish
  • Biodiversity of marine life
  • Save the Scallops
  • 100 million sharks are killed each year

Shark Classification

  • Sharks fear humans more than humans fear sharks

PRODUCTS MADE FROM SHARKS

  • What is a sharks classification? They belong to group of fish called Selachimorpha characterized by having skeletons made from cartilage, five to seven gill slits and a pectoral fin.
  • Sharks are sisters to the ray and skates family.
  • Almost every part of the shark can be used.

Food Chain...

  • The flesh can be eaten.
  • Its fins are used for 'shark fin soup' and animal treats.
  • Its skin used for leather.
  • Teeth made into jewelry and ornaments.

-All sharks are carnivores, meaning they are meat-eaters. Most have razor-sharp teeth made for tearing the flesh of prey. Sharks mainly eat other fish and at times they may even eat other sharks.

- Most scientists do not believe there is any link between a sharks diet and their desire to attack and eat humans. Most humans are attacked because they were in the wrong place at the wrong time. Sharks are not specifically hungry for humans.

- When a keystone predator disappears from a community, the community becomes unstable. The ecosystem will eventually collapse.

  • Vitamin A supplements
  • Ladies' cosmetics

  • A mistaken perception that has gained public acceptance
