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!!!!
