How does non-poisonous snakes kill there prey?

Pythons and boas are the most well known of the snake species that use constriction as a method to kill their prey.  This is a very powerful method used by the non-poisonous snakes like anaconda. Constrictors typically prey on large animals that can cause serious injury to the snake if they are not first incapacitated. The method used by these snakes is to tighten their body around the prey, resulting in suffocation – they do not crush their prey. The snake typically bites the prey to hold on as he quickly wraps his body and tightly coils around the prey. Each time the victim exhales a breath the snake tightens, preventing the animal from inhaling more air. Means the victim has a feeling that as and when he breaths out the coil of the snake becomes even more tight preventing the prey to breathe again. Without an air supply, the prey rapidly becomes unconscious and usually dies. The snake then inject the prey.

Which water species is very close to Human beings?

Bottlenose dolphins are the most common and well known type of dolphin. Female dolphins are called cows, males are called bulls and young dolphins are called calves.  Dolphins often display a playful attitude which makes them popular in human culture. They can be seen jumping out of the water, riding waves, play fighting, occasionally interacting with humans swimming in the water and also love to swim in front of the moving boats or ships. Dolphin is a mammal so it has to come on the surface of water to breath it use a blowhole on top of their heads to breathe. Dolphins have excellent eyesight and hearing as well as the ability to use echolocation for finding the exact location of objects. Dolphins communicate with each other by clicking, whistling and other sounds. Some dolphin species face the threat of extinction, often directly as a result of human behavior. Some fishing methods, such as the use of nets, kill a large number of dolphins every year.

How do eagle catch a fish?

The eagle's eyesight is especially remarkable. With vision about five times sharper than our own, an eagle can spot a target as small as a rabbit up to a mile away.   The claws on an eagle's toes are curved and razor-sharp for catching and holding their prey.  Rough bumps on the eagle's toes also help them hold slippery, wiggling fish. A eagle’s feet are important for capturing food and also as a method of protection.  To catch fish, eagles generally watch the water surface from a perch or while soaring in the air. Then they swoop down close to the water and drop their feet right in the water to catch the fish.   Unlike other birds, which eat seeds or insects and travel only short distances in search of a meal, the eagle must often fly great distances in order to find worthy fare.  Riding upon vertically spiraling columns of warm air called thermals, the eagle can travel up to twenty miles per hour virtually without effort. The eagle is further aided in flight because its bones are hollow. Unbelievably, the total weight of an eagle skeletal system is only half the weight of its feathers! With a wingspan of seven to eight feet and a wide and rudder-like tail, the eagle was built to master the skies.

Which is the most powerful predator on both land and trees?

The Puma is a large Cat   found in the mountains from Southern Canada to the tip of South America also commonly known as  the Mountain Lion. The Puma has no markings on its fur leading to its scientific name Felis concolor which means 'cat of one color'. They have pointed ears and their acute hearing allows them to detect prey even when it is too dark for them to see. Puma can easily adapt to their natural habitat, they can hunt both on land and on trees comfortably.  This big cat unlike other member of their family is not able to roar.  Puma cubs are born blind and are completely helpless for their first two weeks of life until their blue eyes fully open. The Puma is a large and powerful carnivore, hunting and eating only other animals in order to survive. The Puma is one of the most dominant predators throughout much of their natural environment and are therefore rarely preyed upon by other species.   The biggest threat to the Puma however is people who have hunted this large Cat. In some areas they are also hunted by ranch owners who blame Pumas for their loss of  livestock.

 
 

How does desert snake move in hot sand?

The desert snake Pit Viper, the sidewinder has a distinctive hornlike projection over each eye. It is chiefly nocturnal and takes refuge in the burrow of another animal or under a bush during the day. At night it emerges to hunt its prey. A desert inhabitant, this snake moves with a sideways motion, known as sidewinding, thought to be the most efficient mode of movement for a snake on sand. It throws its body into lateral waves, only two short sections of it touching the ground. All the snake's weight, therefore, is pushing against the ground at these points, and this provides the leverage to move it sideways. As it travels, the snake leaves a trail of parallel J-shaped markings. An movement  of this snake in open, sparsely vegetated country, has an advantage of reducing contact between the snake's body and the hot sand. 

Which part of the world is snakes heaven?

 The island Ilha de Queimada  in Brazil is inhabited completed by venomous snakes. There is exactly no predator for these snakes on the island which resulted in the tremendous increase in there population so it is assumed that on an average there are five snakes in one square meter area. The poisonous  snakes like The King cobra and vipers are found on this island. However, the deadliest snakes to be found there are the Golden Lancehead viper. According to statistics, about 90% of deaths resulting from snake bites in Brazil are caused due to bite from this snake. A single bite of this snake contains enough venom to kill two humans at a single time. Several tales have been associated with this snakes island. Mostly, the dense population of snakes has kept humans away from the island but according to those tales, a fisherman once wandered off the to the island, only to be bitten by one of the thousands venomous snakes of the area. He barely made it to his boat before giving up his life. The snakes venom causes the skin around the bite to melt away, making survival chances of the victim extremely slim. Human habitation is nil on the island. Only scientific persons after having granted permission to do so can visit the island. The snakes live mostly on migrating birds that stop on the island for rest. A plan to establish a banana plant on the island had been proposed at one point. However, for obvious reasons, it was never established.
