Why do rabbits have white tails?
480348
One theory is that when feeding in the dusk, rabbits run to their burrows on the least alarm, and that it would be very important for those who were furthest off, and especially for the young, to be able to follow the others without any hesitation in a straight line. The upturned white tail thus serves as a useful guide.

Polar bear fur is actually clear and completely colorless.  The reason it appears white is because it scatters light.  If you'd like proof, check the web link below.  \nGood question!

Alyss, thank for being brave enough to ask.  You deserve a straight answer.  No such thing as a rabbit/hare/jackrabbit with antlers.\n\nSuch a critter is called a "jackalope" and is fabricated by imaginative taxidermists to confound the gullible.  It is a joke.  Some look quite real, though.  The idea comes from the fact that male rabbits are called...  Bucks!\n\nH

A Lynxes ear tufts enhance thier hearing, acting kind of like antenna to pick up vibrations in the air. The reason why they have ear tufts is because of natural selection, the tufts give them an advantage in hunting so it is a desirable trait. There are other theories but they are not supported by evidence. One is that the tufts keep the lynxes ears from freezing in winter, but the Caracal also has ear tufts and does not experience winter, again it has also been supposed that the tufts help to confuse thier primary prey (Snowshoe hare) because they resemble rabbit ears, again the Caracal(desert lynx) who also has ear tufts does not hunt hares. The reason why they are black is anybody's guess it probably has to do with visibility and camoflage.

this one cause a arguement. my ex-boyfriend thought cats and dogs have no bones in their tails. may not have been the answer you were expecting but i still think it's a pretty dumb thought.

No.  Bunny is a colloquial term used to refer to cute little fluffy rabbits.  It is believed to derive from the cute little fluffy tail, which looks kind of like a bun.  \n\nMuch like kitty, it is just a nickname given to cute rabbits.\n\nOriginally, rabbit just refered to the young bunnies, and adults were called conies, but eventually the rabbit term was applied to all ages of the critter.\n\nThere are differences between rabbits and hares, however.  Hares tend to be longer, leggier and rangier, live mostly solitary lives, and have precocial (well developed) young.  Rabbits are more compact and fluffier, usually live in large family units in burrows and warrens, and have altricial (helpless) young.\n\nRabbits are more common in Europe, while hares are the predominant lagomorph in North America.  Jackrabbits, despite their name, are actually hares.\n\nHope that didn't confuse you even more.

Rabbits are small mammals in the family Leporidae, found in many parts of the world. They are sometimes affectionately known as bunnies, especially by children. There are seven different genera in the family classified as rabbits, including the European Rabbit (Oryctolagus cuniculus), cottontail rabbits (genus Sylvilagus; 13 species), and the Amami Rabbit (Pentalagus furnessi, an endangered species on Amami Oshima, Japan). There are many other species of rabbit, and these, along with cottontails, pikas and hares make up the Order Lagomorpha. Rabbits generally live for about 4-10 years.\n\n\nRabbits have been a source of environmental problems when introduced into the wild by humans. Because of their appetites, and the rate at which they breed, wild rabbit depredation can prove problematic for agriculture. Gassing, barriers (fences), shooting, snaring and ferreting have been used to control rabbit populations, but the most effective is diseases such as myxomatosis ('myxo' for short), and calicivirus. In Europe, where rabbits are farmed on a large scale, they are protected against myxomatosis and calicivirus with a genetically modified virus. The virus was developed in Spain, and is beneficial to rabbit farmers. If it were to make its way into wild populations in areas such as Australia, this could create a population boom, since those diseases are the major threats to the rabbits' survival.

I guess its because they eat different things- shells are essentially made up of certain things that the animal eats. Also, I guess from an evolutionary point of view, an animal ends up with either hard or soft shells based on the environment within which they live. They would need a hard shell if they were living in difficult surroundings where damage would be easily possible. So its more complex than you'd think! Good luck!

Hope this stuff will help you out...\n\n\n"Rats live all over the world and can adapt to a variety of environments. Some people dislike rats' long tails, but the tails are very important, because they allow rats to be excellent athletes. Using their tails for balance, rats can jump long distances and land on narrow ledges. Rats can balance on ropes, wrapping their tails underneath to help hold them on. Although rats can see, they do not see very well. Instead they rely on their excellent hearing and sense of smell. A rat's whiskers also help it gather information about the world."\n\n"Muskrats have two unique adaptations that help with survival. The first is the shape of their nostrils. They look like the number seven. The shape of the nostrils allows muskrats to inhale remaining oxygen from recently exhaled breath. This allows for muskrats to swim under water for up to 15 minutes. The other adaptation has to do with how the muskrat got its name. Muskrats are named because of the musk glands located near the underside of their tail. These secretions are used to warn other muskrats to leave this muskrat's territory alone. This keeps other muskrats away which in return cuts down on competition for food and mates. This aids in the muskrat's survival"\n\n"Kangaroo rat adaptations for two-footed hopping include elongated hind limbs, a long, tufted tail for balance, a shortened neck and a large, flattened head."

maybe because they are less agile than that of a smaller animal there by needing only to consume such quantity of food, and also bigger animals has the ability to conserve energy in their body......i guess

Not sure about the rabbits foot, but the horse shoe is because of an old belief that witches are scared of iron.  In olden days the easiest sourse of iron was a horse shoe, so people would hang one above the door.  I live about 5 miles from where the last witch in Britain was burnt (in like the 1600's), and there's still a lot of belief in witches.  My mother specifically bought a rowan tree to plant on our drive, witches are also supposed to be repelled by rowan trees.  There's a forest near me that has a series of circular clearings throughout it, which witches still go to on midsummers nights eve to dance round a fire naked (it takes all sorts I suppose)

RABBIT'S FOOT\n \n Do you carry a rabbit's foot for luck? If so, is it always in your left pocket? Are you sure it was the rabbit's left hind foot? And, most important of all, was the animal killed at the full of the moon by a cross-eyed person?\n\nIn spite of all these requirements for luck most rabbit-foot charms today are only small front paws. But thousands of people never go without them.\n\nThe first superstitions developed about the European Hare, a perfectly harmless animal. He's larger than his cousin the rabbit, having powerful hind legs and tips of black on his long ears.\n\nThe ancients noticed many things about these timid creatures that they couldn't explain. Because of this they thought of them as both good and evil. They saw how they came out at night to feed, how they gathered in bands on clear moonlit nights to play as if influenced by the moon. Another astonishing observation was that northern hares were brown in summer and white in winter.\n\nLike the cheetah and greyhound, the hare's rear feet land in front of its forefeet when running swiftly. This was impressive to primitive men. Hares also thump the ground with their hind legs as if speaking with them. These observations about the hare's hind feet were the reasons for them becoming looked upon as powerful charms against evil forces.

Why so some snakes eat mice and rats?

Because it's warm-blooded,  has fur, and gives milk.  (Even though it also lays eggs, which is very un-mammalian, scientists just agreed to classify it that way because it's more like a mammal than anything else.)

there really isn't a reason (see note below) we have this exact distribution of life.  species are constantly changing, however slowly.  sometimes one set of a species will become separated from another set.  each set may change in a different way.  so, many generations after the split, the two sets may not appear at all the same species.  We have just made a new species.  This has happened millions of times in the past.  scientists have evaluated structure and function in many species, and pieced together reasonable estimates of how tthings got to the way they are today.\n\nAnother way of answering your question is, within an ecosystem balance is necessary.  We need a good mix of plant, insect, bacteria, animals, etc., to support our world, and have had millions of years to reach that equilibrium.  A certain number of rabbits are required to support a certain number of foxes.  If too many foxes live in an area, they will deplete the rabbit population.  the rabbits will be harder to find, the foxes will get hungry and move on.  The fox population is now artificially low, so the rabbits exceed their ideal population.  It's easy to find them so foxes come back ...\n\nNOTE:  or God said that's how it is, depending on which side of the Science-Religion fence you sit.

I typed albino deer into Google search.\n\nAlbino: Among the questions most often asked are "What causes some deer to be albinos?" "How common are they?" "Are they protected?" and "Can they reproduce?" Albinism is a recessive trait found in mammals, birds, reptiles, fish and even plants. These plants and animals do not have the gene for normal coloration and do not produce the enzyme responsible for skin, hair and tissue coloration. Albinism is the total absence of body pigment. The eyes of an albino are pink, because blood vessels behind the lenses show through the unpigmented irises. As you might guess, albinism is not a desirable trait for either predators or prey species. Being totally white year-round makes concealment difficult. Also, many albinos have poor eyesight. In the game of life, where survival of the fittest is the rule, albinos have a strike against them from the start. Perhaps that is why albinos are rare.Because albinism is a recessive trait, both parents must carry the gene before it can occur in their offspring. An albino deer bred to another albino would have only albinos. An albino bred to a normal deer with no recessive genes for albinism would produce all normally pigmented deer. Offspring from this cross would carry the recessive gene for albinism but would be normally colored. When carriers of albinism breed there is a one-in-four chance they will produce an albino fawn. Recessive genetic traits typically become less common unless they confer a survival advantage or are artificially enhanced through selective breeding. Based on hunter reports, about one deer in 30,000 is an albino. Not all white deer are true albinos. Some white whitetails have normally pigmented noses, eyes and hooves. This is a genetic mutation for hair color but not other pigments.

it'd be better if u said what do u call a funny RABBIT Harlarious cause it IS a Hare. and there are lots of things that have hair WE have hair so not really funny.
