Proportionally, the elephant's brain is the most sizeable at a mass of just over 5kg. Although the largest whale is 20 times the body size of an elephant, its brain is just under twice the size. The need for such a large and complex organ becomes clear when we consider the behaviours and abilities of these animals. Elephants are capable of a range of emotions, including joy, playfulness, grief and mourning. In addition, elephants are able to learn new facts and behaviours, mimic sounds that they hear, self-medicate, play with a sense of humour, perform artistic activities, use tools and display compassion and self-awareness.
Part of the reason that elephants possess such a superior level of intelligence is the structure of their brain. Their neocortex is highly convoluted, as it is in humans, apes and some dolphins. This is generally accepted to be an indication of complex intelligence. The cortex is thick and comprises many neurons. The elephant is one of the few creatures (along with human beings) that is not born with survival instincts, but needs to learn these during infancy and adolescence. The brain is specially designed to accomplish this sort of life learning. Elephants and humans have a similar lifespan, and plenty of time, approximately 10 years, is allowed for them to learn before they are considered to be independent adults.
TThe lessons learnt include how to feed, use tools and understand their place in their social structure. Elephants capacity for memory and emotions is remarkable and is due to the well-developed hippocampus. This is also the area responsible for emotional flashbacks and is the reason that elephants experience Post-Traumatic Stress Disorder.
