  • Great White
    View slide
  • Great Whites have a life expectancy of 25 years but only start mating on the last five.
    Their length on average reaches 4 meters
    Sharks live on the coasts of every continent except Antarctica.
    A Great White produces from 2 - 12 pups, all about 1.5 meters long.
    In the womb the pups feed on unfertilised eggs and their own brothers and sisters.
    As soon as they’re born they swim away to start their own life.

  • Little Facts
    • It is the most common shark to be used in movies.
    • The longest ever caught nearly reached 7 meters just off prince Edward island 1993.
    • Dogs kill more humans in a year than sharks in the last 100.
    • Their arch nemesis is the Orca (The killer whale) the sharks are at a disadvantage as the Orca hunt in packs, are quicker and more agile, despite being bigger.
    • They rarely fight for food, but if they do they settle it with a tail slapping contest.
    • They can roll their eyes to the back of their head.
    • A shark’s liver makes up 24% of its body weight.
    • They generate up to one thousand teeth.(THEY DON’T NEED A DENTIST)
    • This beast can eat sea lions whole.
    • A shark can last 3 MONTHS without eating after a big meal.
    • A Great White can smell a drop of blood in 25 Gallons of water. It's like finding a needle in a hay stack.
  • Orca
    • Female orcas, or cows, normally have 5 calves during their life time which reaches 50 years on average.
    • Male orcas, or bulls, live to 45 years of age. On the very rare occasion some orcas have been known to live almost 90.
    • Male orcas reach the lengths of 23 feet and the weight of 7-10 tons; female orcas only grow to be 21 feet long and to weigh 4-6 tons.
    • Orcas can be found in all of our oceans, but they prefer the colder waters.
    • Orcas can swim up to 30 mph.
    • Orca groups are called pods.
    • Orcas live in a world ruled by cows (female Orcas)
  • Little Facts
    Killer whales have developed a way to beach themselves as a form of hunting.
    They can be classified in three groups:
    Resident - Commonly seen and feast on fish.
    Transient - Travel in small pods and feed on marine mammals.
    Off Shore - Travel in large pods and eat fish, SHARKS and turtles.
    Each pod has its own verbal dialect. There are recordings of a mother teaching its off-spring the verbal pattern.
    Noise pollution from boats makes it difficult for whales to use echolocation.
    They belong to the dolphin family.
