Occasionally, vampire bats feed on human. Once a host is spotted usually a sleeping mammal, vampire bats approach the target on ground and land.  They are able to locate where to bite by using their infrared sensors. In case the located host has fur, they use their razor sharp teeth in making a 7mm long and 8mm deep cut. Did you know that these little creatures can consume blood up to five teaspoons in one sitting! And for survival, vampire bats will eat other vampire bats as a food supply resource.

Pythons are non venomous snakes that are found in Asia, Africa and Australia. Python generally ambush and then kill its prey by means of constriction. It feeds on almost everything that comes its way using a set of organs that can detect heat and a tongue with sensor capable of detecting animals scent. Its diet includes; rodents reptiles, amphibians, birds and other mammals. Python can ingest prey bigger than its head by slowly squeezing the helpless victim. It usually swallow its meal starting with the victim’s head. A large meal will probably take  days or even weeks to be totally digested since pythons have slow digestive system. In this case, the snake may not need to eat again for months.

We always taught that small animals eat less, but don’t say that to the hummingbirds. Considered the world’s smallest bird, hummingbirds have a very odd eating habit.  They need to feed every 10-15 minutes, usually sipping the nectar of a flower or even preying on spiders and other insects when feeding young. Hummingbird’s heart beats 1,200 times/minute and flaps it wings 200 times for the same period. This tiny bird needs all nutrients it could get. Luckily, humming birds have an incredible metabolism.

We all know that butterflies and moths do come from caterpillar. But did you know that, this small creature top our list of “eating machines.” Most caterpillar are known herbivores, and are voracious leaves eaters. Caterpillar grow very quickly, usually shedding their skin four or five times before it transform to an adult form. As an example, tobacco hornworm can grow ten-thousand times its weight in about 20 days. Another species, the tobacco hornworm can consume 1,000 its bulk in less than three weeks. Caterpillar’s voracious eating habit is based more on biological adaptability.
