  2. Introduction • The scientific name for Great White Shark is CarcharodonCarchias. • Is it endangered? Yes it is. • They live for about 20-30 years but some can live for a little more than 40 years.

  3. Physical Features • Sharks are mostly about four feet big, • sharp teeth, • about several fins, • two big eyes at the front and side of the body, • most sharks are gray, • many teeth to attack prey easily, • Gills take oxygen from water so they can breathe.

  4. Where They Live • Shallow or deep water in the ocean depending on species. • Warm or cold water depending on the species. • They live in every continent. • There are fish everywhere!!! • Lots of trash covers the ocean floor. • They like to live here because there is lots of stuff to eat and they also have no choice!

  5. Dinner Time! • Predator To • Seals • Sea Lions • Other smaller sharks • Some eat trash from ocean floor Prey Of • Killer Whales • Humans • Marine Snails eat egg cases

  6. Reproduction • The mating season depends on what kind of shark. • Some sharks go to shallow water to hatch eggs, but most sharks are born alive. • The mom doesn’t stay with the baby. It just leaves it behind. • Eggs are called Mermaids’ Purses.

  7. Behavior • They never stop swimming. • They migrate a long distance to give birth. • They live in different temperatures based on the type of shark. • They work together with fish that eat small parasites off their skin. • Their eyes roll back into their body when they are about to attack.

  8. Physical Adaptations • Gills take oxygen from water so it can breathe underwater. • When teeth run out, they move up a row. • Many teeth so it feeds easily. • Great Whites have dark backs for camouflage. • Every fin helps the shark with moving.

  9. Behavioral Adaptations • Great Whites leave a bite mark for warning the prey to go away quickly. • They team up with a certain fish that can eat little parasites off the skin. This protects them from skin infection • Hammerheads stay in a “school” when they try to choose mates. • Migrate long distances to give birth because they need the warmer water • Their eyes roll back in their head when they attack to protect them from being damaged.

  10. Physiological Adaptations • Bones made of cartilage for flexibility. • The Ampullae of Lorenzini is a sensor so the shark can catch its prey in dark waters. • Good sense of smell which helps them smell blood from far away. • Gills take oxygen out of water which is how they breathe.

  11. FunFacts • Sharks have bones made of cartilage so they have a lot of flexibility. • They work together with a fish that can eat bad things off their skin. • Some sharks eat trash off the ocean floor and are called “swimming trash cans”.
