great White Shark

1- Colour, The great white shark is only white on its underside. The great white shark is actually bluish grey, to be able to camouflage itself to be a more successful hunter.

2. Multiple gills, most sharks average 5-7 gills per side. This is because they they take in alot of oxygen. They ram oxygen into their body while they move forward if they stay still they will actually die from lack of oxygen.

3. Teeth, sharks have up to 300 teeth, however they have no bone so they loose teeth quite frequently, and will normally get stuck into prey while attacking, almost acting like a knife. They grow back very quickly but not in the same place.

Warm blooded- The great white shark is one of a few sharks to be warm blooded, with how deep the great white shark goes its able to heat up its own body, unlike cold blooded who adapt to the temperature, which may cause its body to malfunction do to extreme temperatures.

Cartilage-This type of skeleton means that the shark is lighter, as cartilage is about half the density of bone. This is crutial because, unlike other fish, the shark has no swim bladder, which is a gas pocket in a fish which helps it stay afloat in its water depth without having to waste energy on swimming helping it float. So the lack of weight help it to prevent it from sinking to the bottom of the ocean. Therefore, it needs to remain light in weight, not weighed down by heavy bones.

Reoroduction-As in other sharks, the Great White practices internal fertilization. Mother Great Whites retain yolky, thin-shelled eggs within the body until development is complete. Such a reproductive mode is called "ovoviviparity". After a gestation period of a year or longer, 5 to 10 (and possibly as many as 17. 3 to 5 foot-long baby sharks are born in shallow coastal areas. After birth, the pups receive no care and are left to fend for themselves. The Mother shark can take up to a year to replenish her energy after birth.

Sharks do not chew their food, so they have intense stomach acids that help digest food. and can even digest bone! it is thought sharks had to make this adaptation due to having a useless tongue that doesn't help them chew food.

They can be seen near the surface or near the bottom of the sea, as far deep as 820 feet (250 meters), but they're rarely seen in the middle of those two extremes, so that makes their habitat extremely hard to narrow down they also enjoy like reefs due to the amount of fish. they tend to like fairly rocky areas to hang around.

The Great White is primarily an inhabitant of cool temperate waters over continental and insular shelves. It seems to prefer areas with rocky bottoms, but it has been recorded over sandy bottoms and on coral reefs as well as in the deep-sea.

It was formerly thought that Great Whites do not enter kelp forests, but this has been shown to be false: not only do they enter kelp forests, they apparently also feed there.

Preditor- If the great white shark is truly the ocean's top predator, why would it be so scared of killer whales? it turns out that killer whales have been known to prey on sharks. This is the one thing a great white shark will constantly "run" away from.

Prey- The baby greats like to eat rays, fish and other sharks! While the larger ones eat much larger pray, such as Sea otters, seals, and small toothed whales. They often eat floating dead animals.

Dna Evidence of evolving- The great white sharks ancestor the Megalodon grew up to 18m in length, which made it extremely hard to feed itself with other competition who is faster, so the only the smaller sharks would survive long enough to reproduce, and they just kept getting smaller due to success rate on hunting and calorie consumption to body mass. making it into one of the sharks with us today, or many.
