  1. THE KILLER WHALE By: Matthew Adams

  2. Classification

  3. Physical characteristics The orca’s eye is below the eye spot It has a saddle behind the dorsal fin Female dorsal fin=3ft Male dorsal fin=6ft

  4. Compare MALE 6ft FEMALE 3ft

  5. Distribution • The orca lives basically in every aquatic habitat • Mostly along shorelines for food • Don’t migrate if there is plenty food, good temperature and not a lot of pollution

  6. Habitat • Orcas live from the tip of Alaska down to the ice of Antarctica • If there is plenty of food orcas stay in most bodies of water

  7. Conservation • The orca is data deficient and therefore has no conservation status • The combination of potential declines driven by depletion of prey resources and the effects of pollutants is believed sufficient that a 30% global reduction over three generations DD

  8. Parental care • The bond between a mom and her offspring is like no other • Rarely does the calf leave its mother • Mother gives birth to one calf tail first after a gestation period of 15-17 months • the female orca is mature at 6-10 years old and males mature at 12-16 years old

  9. Longevity and mortality • The killer whale lives up to 30 years if it is male and 50 if it is female • However in captivity the average is about 5-12 years depending on the generation

  10. Diet/predator relationships • The killer whale if healthy rules the sea and is the top of the food chain • The killer whale is known to eat anything that it finds • The orca does not undergo torpor because it has voluntary breathing and needs to be half awake at all times

  11. Human relationships • The orca is fascinating to us so humans use it for • Zoos • Circuses and shows • Skin • We once shot a couple with our naval aviators when they messed with the fishing turn outs in iceland

  12. Fun facts • Top of the food chain • Sharks are scared of and run from orcas • Scientist are trying to make a shark repellent • The orca supposedly got the name killer whale from a miss-communication of “whale killer” • The only human attack was on a surfer who was later spat out when the orca maybe realized that it was a mistake
