Big Tuskers are now few and far between but to be able to photograph and spend time with such a gently magnificent beast is something you treasure forever.
To the casual observer elephants are largely silent animals, except for the occasional trumpet or squeal, made to show alarm or aggression. This magnificent animal comes across as silent because most of their ‘language’ is infrasound, meaning it is below the human hearing range. Humans can hear as low as 20hertz. Most of elephant communication is done between 4 and 20hertz. The occasional ‘tummy rumble’ can be heard by humans and this in effect is the highest pitch in elephant communication.
These ‘Tummy Rumbles’ are not tummy rumbles at all they are made at the base of the trunk. Basically where the trunk enters the skull, what we would call the nose cavity. If you are ever lucky enough to be close to an elephant while they are communicating, you will notice that the base of the trunk vibrates and you ’see’ the noise without hearing it. Noise is basically vibrations that have been interpreted by our ears and all make sense in our head but travelling through air are just vibrating particles.
This infrasound communication is thought to be amplified by the huge honeycomb structured skull. The skull is honeycomb for two reasons, firstly and probably most importantly to make it light enough to carry around. If an elephant skull was made of solid bone being the size it is, it would easily be a few 100 kilograms, this would be very impractical even for the largest land mammal. The Second reason is to ampify this ’silent’ communication, even though humans can’t hear it these rumbles can be heard by other elephants as far as 4 or 5 kilometers (2 to 3 miles) away.
These ‘tummy rumbles’ can be heard 4 to 5 kilometers away as airborne communication. But that’s not the only way elephant send and receive. These vibrations can travel a lot further in a harder substrate such as soil. These siesmic waves can travel as far as 20 kilometers (12 miles) under ground.

Most of elephant communication, is made at the base of the trunk. What would look like the forehead, this means the vibrations can be amplified by the honeycomb structure of the skull. Other sounds made by elephants include trumpeting and squealing, this is done by expelling air rapidly through the trunk.
It is very interesting how elephants pick up these under ground vibrations. There are two basic methods that we know of, the first one is through bone conduction. This is when vibrations in the soil are transferred into the tips of the elephant’s toe bones and then up the leg and so on into the middle ear where the vibrations are read and translated into messages in the brain. The other method is through ‘Somatosensory Reception’ this involves vibration sensitive cells in the feet and tip of the trunk that pick up vibrations which then travel to the brain via the nerves system. This method of ‘hearing’ results in the ‘receiving stance’ as I like to call it. Often out in the bush when you are watching elephant they suddenly, without warning all freeze, motionless for sometimes minutes at a time. If you didn’t now about this seismic communication you would think that time had stopped, not a sound and the whole herd unbelievably still even the young ones seem to pick on this and listen in. Even though you can’t tell for sure you can imagine these beautiful creatures talking to herds on the other side of the reserve, it’s an unbelievable though that there is a whole conversation going on without you hearing a thing.
As far as we know there are also different calls and messages sent, these may include warnings rumbles, aggressive rumbles, rumbles made by females in estrus, rumbles made by bulls in musth, and probably many many more that humans can’t even start to imagine.
These are unbelievable animals, and we have only scratched the surface of their world. People often think and relate to animals in a human way of thinking, the truth is that compared to animals our own senses are far inferior. Huge respect has to be given to the creatures of earth-
There is still so much we don’t know!
Amazing studies have been done by Caitlin O’Connell-Rodwell, in places like Etosha, to find out more about elephant communication-

Elephants are usually peaceful animals, this young female was a little bit wary of me being so close. She was pretending to feed while keeping an eye on me just to make sure I was not a threat to her.
