Introduction The scientific name for Great White Shark is Carcharodon Carchias. Is it endangered? Yes it is. They live for about 20-30 years but some can live for a little more than 40 years.
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.
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!
Dinner Time! Prey Of Killer Whales Humans Marine Snails eat egg cases Predator To Seals Sea Lions Other smaller sharks Some eat trash from ocean floor
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.
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.
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.
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.
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.
Fun Facts 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”.
