SOME ANIMAL FACTS... HARD TO BELIEVE BUT TRUE
(Najamuddin Ghanghro, Karachi (original from Larkana))
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

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. (Check the LinkCloud below to find out more).
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
