Which is the successful cross of Lion and Tiger?

 The Liger is the largest of the world's biggest cats, known to grow up to 12ft tall when standing on their hind legs. Created by the mating of a male Lion with a female Tiger.  The Liger generally has a more Lion-like appearance. The Liger  also inherited the spots found on the backs of Tigers ears along with the tufted fur around their chins. In the wild, it is common for Tigers to enter water either to catch prey or to cool down in the heat and so they are naturally good swimmers, which is something that the Liger seems to have inherited. Another odd thing is the fact that the Liger appears to make both Lion and Tiger noises but it's roar is more like that of a Lion's. The reason as to why Ligers would be rarely produced in the wild is that if a male Lion and a female Tiger came across one another, they are much more likely to fight to defend their territory or avoid one another completely in order to avoid risk getting hurt.

Why snake's tongue is in two parts?

Snakes use their senses to hunt, escape danger, and to find a mate. Since most snakes have poor eyesight their other senses need to make up for it. Snakes don't have noses like we do.  They have nostrils to breathe with but snakes smell with their tongues.  When a snake sticks out its tongue it smells its surroundings.  The moist tongue collects scents and small organisms from whatever it touches and from the air around it. The first half of the snake tongue gives information about the animal odour and the next half gives information about the distance that animal is from snake.  When the tongue goes back into the mouth the forks touches a special sensory organ called the Jacobson's organ on the roof of the mouth and tells the snake what it smells.  Snakes have a small notch in their lips that they can stick their tongues through so they don’t need to open their mouths. Snakes can absorb vibrations through the ground and determine the size of the prey or danger by its movements.

Can snakes fly in air?

 Flying snake is a misnomer these animals can’t actually gain altitude. They’re gliders. Once thought to be more parachuters than gliders.  To prepare for take-off, a flying snake will slither to the end of a branch, and dangle in a J shape. It propels itself from the branch with the lower half of its body, forms quickly into an S, and flattens to about twice its normal width, giving its normally round body a concave C shape, which can trap air . Flying snakes are technically better gliders than their more popular mammalian equivalents, the flying squirrels. There are five recognized species of flying snake, found in western India  . Knowledge of their behavior in the wild is limited, but they are thought to be highly arboreal.  They are mildly venomous snakes, but their tiny, fixed rear fangs make them harmless to humans. It is been assumed that the flying snake has adapted themselves in order to escap from there predator. They glid from one tree to another without touching the surface of the earth, this ability also helps them to catch there prey.

Which animal can walk on water?

The Jesus Christ Lizard is an extraordinary reptile which can run on water when threatened. This species is the most commonly encountered, especially along streams and lakes of Costa Rica. When threaten the Jesus Lizard escapes by speeding to the nearest edge of water and continues sprinting. The lizard runs on only its hind legs in an erect position, holding its arms to its sides. The lizard is well balanced on water because its feet are large and equipped with flaps of skin along the toes, when moving quickly, the lizard can cross a surface of water before sinking. On water it runs an average speed of 8.4 km/h, which is just a little slower than its speed on land. Younger lizards can run 10 to 20 meters on water, while adults cross only a few meters before sinking. Adults do not move slowly, but they weigh more and cannot sprint for as long as the young one can. Once a lizard submerges, it continues swimming until it is sufficiently far from its predators. Although this lizard stays close to water to escape terrestrial predators, it swims only when necessary because there are aquatic animals which can also feed on the lizard if they ever got a chance.

Which animal can stop its heart beat for more than six months?

A much more complex strategy for winter survival is freeze tolerance, the ability to endure the actual formation of ice within the body. Ice forming in body tissues can do a lot of harm. Ice crystals can puncture small blood vessels, squeeze and deform cells to the point of breaking. And even if ice doesn't break into cells, it leads to their severe dehydration, for water is sucked out of cells into the growing ice crystals leaving behind a shrunken and damaged cell.  The Wood frog is one among the example, their soft, water-permeable skin is no barrier to ice and so, whenever frost penetrates into their winter home, they freeze. Ice penetrates though all of the fluid compartments of the animal and within just a few hours a mass of ice fills the abdominal cavity encasing all the internal organs. Large flat ice crystals run between the layers of skin and muscle, and the eyes turn white because the lens freezes. Their blood stops flowing and as much as 65% of the frog's total body water is converted to ice. Breathing, heart beat, and muscle movements all stop and the frozen frog exists in a virtual state till the winter period ends. The frog’s body once again comes into the normal state whenever the ice gets melt.

Why do migrating birds fly in V-Shape?

 

   It has been observed that as each bird flaps its wings, it creates uplift for the bird immediately behind . By flying in a "V" formation, the whole flock adds at least 71% greater uplift force rather  than   each bird flew on its own. Whenever a goose falls out of formation, it suddenly feels the  resistance  to go through   alone and quickly gets back into formation to take advantage of the power of the flock. The "V" -shaped formation that the migrating birds use when migrating serves two important purposes:
First, it conserves their energy. Each bird flies slightly above the bird in front of him, resulting in a reduction of wind resistance. The birds take turns being in the front, falling back when they get tired. In this way, the birds can fly for a long time before they must stop for rest.
The second benefit to the "V" formation is that it is easy to keep track of every bird in the group. Fighter pilots often use this formation for the same reason. Finally, when one among the bird gets sick or is wounded by a gunshot and falls out, two birds fall out of the formation and follow the injured one down to help and protect him. They stay with him until he is either able to fly or until he is dead, and then they launch out with another formation to catch up with their group.

What make KomodoDragon's bite deadful even though it does not have any poisonous venom?

The Komodo Dragon is a large species of lizard that is only found on a islands in the Indonesian.   The Komodo Dragon is an enormous reptile that can grow up to three meters long and weigh 150kg . By flicking it's tongue out of its mouth, the Komodo Dragon is able to taste scent particles in the air to locate both live and dead prey up to 8km away.  They are also known to be excellent swimmers, travelling from one island to another over a relatively long distance.   The Komodo Dragon then chase it's victim with incredible speed and force. Although the majority of initial attacks are successful, if the animals somehow manages to escape then the bacteria transferred from the Komodo Dragon's mouth in the bite causes the flesh to become septic and kills the prey within 24 hours.  The immense size of the Komodo Dragon is thought to come from the fact that they would have once hunted large mammals that would have then existed in Indonesia, including a species of Pygmy Elephant which is thought to have now been extinct for thousands of years.  Despite having slow and docile nature, Komodo Dragons can run at speeds of up to 11mph for short distance and are actually one of the world's known man-eaters.
