OCEAN-
In my opinion the animal that is best fit for suvival in the ocean is the dolphin. They are the one of the smartest animals in the world. It is immpossible to figure out exactaly how smart they are but they are very fast learners and are able to understand and learn complicated commands. Dolphins are also very efficiant hunters. They always hunt in pods (which is like a group of dolphins). They will use their eco locator and follow it to a group of fish. Then they surround the fish on all sides except the top then they take turns getting fish. Dolphins have even fugured out how to sleep under water. They can't really shut down and sleep like we do. Dolphins turn of half their brain at a time and either sleep at the surface with their blow hole above the surface. Or they sleep in shallow water and come up for air every so often. Total they get about eight hours of sleep. They also have the ability to retain water like an animal that lives in the desert. Since they can't drink the salt water they have to get water from their food. And their kidneys are made to hold as much water as possible. And one of the things about dolphins that most makes me think they are the fittest for survival is the fact that they are able to scare away and have even been known to kill a shark. They also have protected humans from sharks and saved lives. That is why they are they are the most fit for survival in the ocean.

DESERT-
Vultures are the world trash men. Now while the vulture may not look that nice, with out them our world would suffer. They clean up the planet by eating the carcuses of dead animals. They are desiged to eat dead animals. Vultures have a bald head so that the can when they are done stuff won't get caught in their fethers which would harvest bacteria and give them other diseases. Then after they eat they go sit in the sun and get whatever is stuck to them baked off. Because the vulture eats the carcuses it rids the planet of desease carrying bugs, like maggots. it also make the world look better. Their stomach is made to handle what ever decayed food they put in their body. Vulture stomachs contain and acid that kill virtully any bacteria. its poop is like a sanitizer and when it is done eating an animal it poops on its legs to clean off any diseases. And just because you see a vulture flying above does not mean there is a dead animal around. Vulture have wings that allow them to soar for hours. They are very smart creatures and soaring in warm pockets of air is fun for them.


JUNGLE-
Tigers are built to hunt. They are the largest of the cat species. A tigers stripes helps to keep it hidden by making it look as though it is broken up, so acts as camoflage. A tiger hunts by stelth to get as close as possible to its prey before it pounces on it. The tigers hind limbs are longer than its forelimbs to help it jump better. But the forelegs are able to twist inward so it can grab and hold onto its prey. And if need be a tiger has strong legs and a flexible backbone to help case prey over a short distance. Tigers paws are also padded to keep noise to a minimum. They also walk on their toes. The front paws have 5 claws but the back feet have 4 claws. Its claws are retractable so as to not damage them from over use. Its head is also an important part of the hunting process. The largest premolar on the top and bottom jaw are used for cutting up the meat before chewing. Tiger on average live to be 15 years old in the wild.


ARTIC-
Polar Bears are one of the largest predators in the world. Polar Bears are also very good swimmers. They have a long neck and narrow head with large flat feet for better swimming. They can swim for hours and over long distances. They can close their nostrils while under water. They can stay under water for up to two minutes. The bears also are perfectly made for cold weather. They have thick fur that covers all of their feet, for better traction on the slick ice. Polar Bears also have a thick layer of blubber which provides insulation from the cold and buoyancy for the water. Polar Bears keep them selves so well insulated that they can over heat themselves. They do not hibernate for winter, since its like winter all year round. But they are less active in the summer. When a polar bear hunts for seals and such it will sit by a hole in the ice and wait for the animal to come up and breathe, then they will stab it in the head with its large teeth and claws, and scoop it out of the water.
