What shark does not eat humans?
People have been killed by whales, but i don't think there are any recorded cases of a human actually being eaten.
Whales come in two groups, toothed whales and baleen whales - filter feeders.
(some of) The toothed family of whales does have the mouths and teeth to take a human apart into bite-sized portions, so these at least have the possibility of eating humans.
But for the baleen whales I don't think it's even anatomically possible.
What size is a grate white shark?
There are no "grate white sharks". But there are great white sharks.
All sharks are deadly to their prey - which is usually fish, seabirds, and seals. Great white sharks sometimes attack humans, but it's usually because we look like seals from underneath - they don't really like our taste, or nobody would ever survive a shark attack.
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.
It's rare that a shark will eat you without smelling your blood. Sharks are attracted to the smell of blood, and unfortunatley can smell it from 5 miles. They will probably circle you for a while before eating you. A shark would go for your torso first and rag you about until it knows you are dead.. After that, the shark would pick of bits of flesh at random leaving nothing behind.
How does the Shark's teeth relate to its diet?
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.

What does it feel like when a shark bites you?
first they will start off at the tip of your finger and then work it's way down a little bit at a time and then it will wiggle around its teeth and that means it is trying to tear your flesh.Although they are circling around your finger that doesn't mean they will try to hurt you. It just depends on what type of shark you have gotten because I got a miniture shark at the beach one time and it bit the living daylights out of me and then I started crying because it bit my finger so bad.

How can a sharks gender be identified?
Sexing: Sexing sharks is a relatively simple task. Male sharks have elongated edges to their pelvic fins that roll up forming sausage-like protrusions called claspers -- or more accurately, myxopterygia (pronounced: mix-op-ter-ridge-ee-a) as they are not actually used for clasping the female -- the front opening of which is the apopyle and the rear opening (as it is a tube) the rhipidion. The claspers are intromittant organs that are used to transfer sperm from the male's ductus deferens to the female's uterus. Some species have small hooks and a spur on the clasper to keep it in place during sperm transfer. Female elasmobranchs don't have claspers, only the opening into which the clasper fits and the waste products exit (called the cloaca - pronounced clow-ache-kah). Females generally grow to larger sizes than males of the same species and some species exhibit sexual segregation for much of the year. (Back to Menu)
Can you see a shark in the water?
Only when they are near the surface and you see the dorsal fin or you have a mask under the waves, but usually not until they are almost upon you..
Did Bethany Hamilton feel any pain when she got attacked by a shark?
She only felt a tug, but she didn't feel any excruciating pain. Sometimes when people get severely injured, they don't feel much pain since the brain already knows there's pain. But Bethany experienced what's called phantom pain, when you feel pain for a limb that's not there and this happens when pain receptors don't reach the brain until after the limb is gone.
