Dear MEL School’s Topic Readers,
Why the elephant has long trunk?
Many know that the
elephant’s large ears help it body temperature cooler. When it’s very hot,
elephants move their large ears like fans. But have you ever thought about why
the elephant has such a long trunk?
New studies found
that the longer the trunk is, the more the elephant can eat and grow. The same
is true for the giraffe for its long tongue. Those gigantic body animals need
to eat substantial amount of food to grow and sustain their weight. The volume
of food required to live seem to have evolved their trunk and tongue longer to
grab more food in wider, higher or lower perimeter.
Enjoy reading and
learning how these animals have evolved to survive.
