We, as humans, used to think that we are the best and only living creature that has the right to live free, so we were killing animals for our own benefits and we were interested to see them in zoo or circus acting for us. This type of selfish behavior and misunderstanding of creation purpose could be controlled if we consider animals as useful and capable beings in many abilities.


Elephants, animals that we know them for their valuable ivory, have amazing abilities which is interesting for us to know about and essential for them to survive. One of those abilities is the power of hearing. Elephants have good hearing detecting as low as 15 Hz whereas human low range is 20Hz. They use infrasonic sounds for long-distance communications which is not in human hearing range. Research has shown elephants hear and respond to each other's loud calls from distances as great as four kilometers away.


In addition, elephant can pick up sounds in a more unusual way. Caitlin O'Connell-Rodwell, a biologist at Stanford University found that foot stomp of elephants can make a resonance at a frequency that other elephants can detect through the ground. large ear bones and sensitive nerve ending in their feet allow elephants to pick up these underground messages.


But after all elephants are still on the edge of extinction because of selling ivory business.
