How do some lizards able to dissolve in there environment?

Reptiles have several natural protective mechanisms, including venom, spines and camouflage. Camouflage is the biological ability to change  into a background using body, particularly skin. Certain reptiles have a constant skin tone that matches their natural habitat others are able to change their skin tone to match different habitats. The ability to change according to the environment helps these animals to help them protect from there predators. Some among the species like chameleon change themselves in a perfection that many times they remain unseen evenif the predators go very close to them. Chameleons are able to change colors because of specialized cells in their skins called chromatophores. There are actually specific types of skin cells for each color that the chameleon can produce. The chameleon causes these cells to activate by sending messages from their brains to their skin cells. This ability also helps these animals to go very close without notice towards there prey.

How do bats hunt at night when they can't see in dark?

The traditional thinking tells that bats come at night because they can see clearly in the dark but , this is however a wrong notion. Experiment done on bats tells that bats can fly comfortably even if its eyes are covered by some opaque material. This was possible because they use sound rather than sight to navigate.  This method of navigation is know as echolocation and it is similar in principle to the sonar that submarines use to navigate the ocean. Some bats eat fruit, many bats eat insects and vampire bats in the tropics feed on the blood of animals. To search for insects a typical bat will sweep an area with sound, sending out 10 beats per second.  When the echoes come back from the prey, such as a fly, the sound pulses increase to more than 25 per second.  This gives the bat a better idea of where the fly is moving.  As the bat near to its prey, it sends out more and more sound pulses as many as 200 per second. Some bats are so good at echolocation that they can detect and avoid wires as thin as human hairs. 

Which animal can predict there end?

The elephant is the only species which is having the most powerful memory as compared to other animals. Their normal lifespan is 60-80 years. The elephant listen by using their legs, which feels the vibration beneath the ground and the way for the source of running water. The elephant is the only species which can predict that there end is near and then he leaves the group and goes towards the place where they are born. Elephants, humans, and Neanderthals are the only animals known to have death rituals. If an elephant becomes sick, herd members will bring it food and help support it as it stands. If it dies, they will try to revive it with food and water for a while. Once it is clear that an elephant is dead, the herd will become very quiet. They often dig a shallow grave and cover the deceased elephant with dirt and branches, and will stay at the grave for days afterwards. If the elephant had a particularly close relationship with its deceased peer, it can show signs of depression. There are also reported cases of elephants burying dead humans they have found in this way.
