there are two kinds of elephants:
african elephants ( with very big ears )
asian elephants ( with smaller ears )
an elephant uses its trunk for breathing,
smelling and picking up favourite foods---such as hay,
grasses and plant roots---
and putting them in their mouth.
to clean off, elephants suck water into their trunks and then hose themselves down.
baby elephants, which are called "calves",
may use their trunks to hold on to their mother's tails.
some calves put their trunks in their mouths to soothe themselves,
like the way human babies suck their thumbs or pacifiers.
an elephant's wrinkly skin is very sensitive.
elephant usually roll around in mud and throw dirt on their backs to keep
their skin cool and to protect it from sunburn and insect bites.
