10 misconceptions about animals

 

According to legends, fables and fairy tales we know many things about the animals that we believe to be true, but in fact they are just common misconceptions. It turns out that an old dog can learn new tricks, and as they grow older spots of leopards do change.

10 myths that many believe to be true, but it turns out that this is more fiction than facts.

Ostriches bury their heads in the sand



The ostrich is the largest bird known, it can run at speeds up to 65 km/h and my foot is able to bend steel rods. And in fact, ostriches do not immerse your head in the sand as a protective mechanism. In case of danger in addition to attempts to escape or fight back these birds are really trying to hide, but that they lay down on the sand. Thus, at a distance, when an ostrich lifted its tiny head seems to be below ground level. But if she shipped really in the sand? Not at all.

Opossums are hanging on the tail



While opossums do have a strong tail and very deftly treated, in fact they do not hang on it and certainly don't sleep in that position. The baby possum a couple of seconds to hang on the tail, but the adults are too heavy for such a stunt. But for the purposes of climbing trees in the clutches of these animals have opposable thumb.

Touching a toad can cause warts



The skin of frogs and toads lumpy, but with warts, they are unable to infect. The reason for their appearance is an inherent human virus, not the skin of amphibians. But do these creatures really better not to touch it, because wart like bumps, some toads contain glands that produce a poison that can cause severe irritation. So be careful of kissing these frogs.

Lemmings commit group suicide



Since the 19th century, we believe that lemmings exposed to suicidal behavior, similar to a cult, and during migration commit mass jumping off of cliffs. Yes, during the growth in the population of lemmings looking for new habitats and sometimes fall off cliffs, but I think it's a group suicide is wrong. Interestingly, the massive drop off a cliff is not the strange rumors that have to endure the poor creatures. In the 16th century, one geographer has suggested that lemmings fall from the clouds during a thunderstorm, and then carry a mass extinction when the earth begins to break through the first spring grass. Impressive.

Earthworm split in half, it becomes two worms



First, Fi. Secondly, bisected earthworm does not become two individuals. If the worm is severed waist, his head part can survive and regenerate, but the tail half will die. However, amazing flat worms planaria – tiny freshwater creatures, belonging to a different type – is able to restore the whole body from a piece with a size of only 1/300 of the original organism.

Red causes aggression.



The widespread belief, which is based on bullfighting, says that the red bulls cloak excites and makes to attack the Matador. In fact, cattle do not distinguish color and, therefore, does not perceive red as a bright shade. And the bulls react to the motion of the cloak and the overall risk hidden in the environment. (They are not to blame, anyone would be furious.)
And optimism into the situation adds to this photo. It depicts a Spanish bullfighter Jose Tomas during a bullfight in Catalonia, after the government's 2011 ban on such events.

Bats are blind



Many bats, small eyes, and about 70 percent of the types of complement the vision echolocation to help them hunt at night. But blind do they? In any case. Merlin tuttle, founder and President of the International organization for the protection of bats, expressly declares: "there is No blind bats. They are perfectly see." So.

Koala is a species



Although these incredibly glorious creature that inspired the creation of many Australian Souvenirs, have a bearish appearance, in fact they are definitely not bears, but marsupials. After birth mother about six months of carrying the baby in a bag. When he grows up, then climbs on his mother's back or clings to her belly, accompanying everywhere. Extremely cute.

Goldfish have 3 second memory



It's funny to think that each time, floating at the wall of the aquarium, the goldfish makes a new journey, because we all believe that it is almost devoid of memory. But no. Studies have shown that these creatures are able to remember and learn. Scientists at the University of Plymouth came to the conclusion that the cycle memory of a goldfish is about three months, and it can even teach you when to expect lunch. There are actually a lot of evidence that fish are as smart as birds and many mammals.

Sloths are lazy



The origin of the name "sloth" is associated with a slow movement, but in reality it is a vain animal associated with one of the seven deadly sins. Yes, sloths are extremely slow, but not lazy. They are simply unable to move faster. Unfortunately (or fortunately, it depends), metabolism, sloths only 40-45 percent corresponds to which has the most animals of similar size. Thus, it is clear why they are investing so little effort in movement, can climb at a speed of 1.8 meters per minute.
