Great White Sharks

Depends on where you are swimming. If you are in Hawaii then you should fear the tiger shark. If your in California then fear the White shark. The largest tiger shark ever accurately measured was 23.9 feet. the largest white shark ever accurately measured was just over 20 feet. However white sharks reach a larger size more commonly than a tiger shark. Tiger sharks will try to eat anything and will not leave you after biting. A white shark will make a massive strike.

It has not been proven how many there are, they are located in Ganges river in India, and most likely be less then 50 around...

port jackson sharks eat reef dwelling creatures such as crabs oysters and sea snails

perfectly safe they are harmless....unless your a fish

because they have like these escalators that push teeth forward when they loose a tooth so their not toothless in a section

it is when two sharks start looking at other sharks

Prehistoric shakrs were WAY bigger than their present day cousins. For example, the Megalodon, a prehistoric cousin of the Great White, was 72-80 feet long! That's way longer than the 20 ft. Great White!

A lot of fish because they need a lot of food like 20% of their body fat

as the king of the river/ swamp etc al. the hippo is slightly stronger

but if your talking about hunting then the crocs are definitely stronger

Great Whites live in all the Oceans except the Artic Ocean in Tropical-temperate climates.

There are no "grate white sharks". But there are great white sharks.

Great Whites are pure carnivores. They are ambush hunters. They take their prey by surprise from below. They usually hunt early in the morning before the sun rises fully, when the visibility is poor. They usually come up fast from below and attack an unsuspecting prey that is at the water surface. During such attacks, the prey may be thrown off from water, with even the shark making a jump out of the water. Sometimes, when an injured prey starts to escape, they are known to chase and finish the hunt.

Great White shark teeth as are those from all sharks are white. Black shark teeth are fossilized ones. The most common color for fossilized shark teeth is a black root with a grayish crown.

The largest crappie ever caught was caught in poplarville Mississippi and weighed 196 pounds and was four foot long!

they can be as hard as a rock

A mammal's teeth correspond to their function: mainly, eating. Herbivorous mammals have evolved a larger number of molars and fewer canines. Carnivorous mammals have evolved a larger number of canines and fewer molars. Omnivores typically have a large amount of each. Anteaters have no teeth as they obtain their diet of ants via their long, sticky tongue, and do not chew their food.

(Were you referring to why a given kind and a given size of tooth may have different shapes in different mammals? It depends on the example.)

For flotation, sharks rely on their liver which is filled with oil and fats.

Their liver has two parts which are filled with oil and fats, substances that are lighter than water helping in this way to float.

Liver is as much as 25% of the shark weight and although it helps for buoyancy, sharks must swim continuously or otherwise they will sink.

anything that can induce tonic immobility upon the shark

Each shark has their own scientific name. Here are a few: Common thresher shark: Alopias vulpinus Cookie cutter shark:isistius brasiliensis Goblin shark:mitsukurina owstoni Dusky shark: Carcharhinus obscurus Frilled shark: Chlamydoselachus anguineus Great hammerhead : Sphyrna mokarran Greenland shark:somniosus microcephalus Spiny dogfish: squalus acanthias Info from- A field guide to the coolest sharks in the pool pamflet.

by swimming!

there is a slight difference, white pointer sharks have white on there bellies so when they are on top of an enemy and they look up all they see is whiteness. great white shark has whitish grey but they don't use it for the same reason. also white pointer sharks put up their dorsal fin and their tail fin (but the tail slightly shorter than the dorsal) but the great white shark only puts up its dorsal fin.

• A lot of people call it a school of sharks but this is supposed to be incorrect but it is the term i use along with my other class mates

Yes! They have extraordinary vision, and can see the slightest movements in the ocean.

Their eyes on the side of their head give them good eye sight.. They can roll their eyeballs back so they get a glimpse in all directions.. They are very good predators and hunt their prey very independently..
