Fast Facts About Sharks

Sharks are vulnerable to fishing pressure because they:
  • Grow slowly
  • Take many years to mature (12 to 18 years in some species)
  • Often reproduce only every other year
  • Have few young per brood (only 2 pups in some species)
  • Have specific requirements for nursery areas (bays and estuaries)
  • Are caught in many types of fishing gear (hook and line, gillnet, trawl)
Sharks have adaptations allowing them to be apex predators including:
  • Teeth that are replaced throughout their life
  • Sensitive smell receptors
  • Eyes that adapt quickly to low light levels
  • Lateral line receptors that sense movement in the water
  • Electroreceptors that detect electrical fields due to the presence of prey
