Elephants
are very intelligent animals, with a sophisticated system of
communicating. Like whales, they can create sounds that are
outside the range of human hearing (called subsonic*
sound). By blowing air through large chambers in their
nasal passages they can create low rumbling sounds that can
carry as far as five miles (8kms). No matter how loudly
you screamed, even through a megaphone or a public address microphone,
you couldn't be heard by another person five miles away! Being
able to communicate with other groups of elephants helps the
elephants to detect danger and warn others, as well as to find
water, which is extremely scarce in some parts of Africa. African
elephants are intelligent enough to be able to detect water
flowing underground and have been seen digging up water in a
riverbed that has run dry. Elephants really are amazing animals!!!!
