A rat can last longer without water than a camel.
Kangaroo Rats can last longer without water than any other animal in the world. Kangaroo Rats live in deserts, lack sweat glands, don´t drink water and survive only by metabolizing water from their food. (Check the LinkCloud below to find out more).
Dolphins always sleep with one eye open.
Dolphins are conscious breathers and can thus only sleep with one half of their brain at a time, otherwise hey would drown. That´s why sleeping dolphins float at the surface alternating their closed eye from time to time. (Check the LinkCloud below to find out more).
A hummingbird´s heart beats 1200 times per minute.
When the hummingbird is in flight, its heart beats 1200 times per minute (the fastest one ever measured was found to beat at 1260 beats per minute). A heart rate this high allows for high metabolism needed for the rapid wing movement to maintain flight. Once at rest, the hummingbird´s heart rate slows down to an average of 250 beats per minute.

A cockroach can live up to a month without its head.
Cockroaches breathe through so-called spiracles which are found in each body segment and the brain does not control the breathing. Besides, due to the lacking blood pressure, cutting the head off does not result in uncontrolled bleeding. Last but not least, without activity, a cold blooded animal´s meal might contain enough energy to be sufficient for up to four weeks. (Check the LinkCloud below to find out more).
