Animal Communication: The Dolphins and Bees

We found this interesting information on the internet







DOLPHINS

What do their sounds mean?

Dolphins use sounds to find objects and hunt to fish.
These sounds are of high frequency and sound out at the rate several hunded per second.
The sounds bounce off objects in the water, are picked up by special tissue in the lower jaw of the dolphin which conducts the echo through to the inner ear. This allows dolphins to identify objects without having to touch them. Dolphins also use the sound to communicate with one another


BEES

Bees communicate with each other about food sources using dances .
The sound from the movements of the bees is picked up by tiny hair on the bee's head: bees use the sun in navigation.
