The Waggle Dance gives theDirection of source of food.
Waggle Dance is based on VectorCalculus.
The quality of food is also
communicated.
The Dancing Also gives the distanceof the source.

Callers: usually make stereotyped
sound
Listeners : respond to the calls by
return calling, by approach, and
by going silent

The area below human hearing is known as
infrasound
Human frequency range is 20Hz to 20K
Hz. Ahumans males voice fluctuates around 110Hz and
females voice around 220 Hz
Among elephants, a typical male rumble fluctuates
around 12 Hz and that of females 22Hz
This signal travels around 10km in favorable
condition and it is called as rumble

When an elephant rumbles a replica of the airborne sound isalso transmitted through the ground and used as seismic signal
Seismic energy transmits most efficiently between the 10 and40 Hz
They sense this seismic signal through bone conduction and theuse of massive ossicles of their middle ears
lso they hit the ground with great force and waves producedbecause of that, they used it as signal of danger

visual communication is how
elephants make use of
postures, displays and their
sense of sight in

Chemical communication explains how elephants usevarious secretions and their acute sense of smell tocommunicate
They use trunk to sniff around and gathers informationabout other elephants and surrounding
Chemical communication provides an energeticallyefficient and long-lasting signal
