With a mass just over 5 kg ((11 lb), elephant brains are larger than those of any land animal, and although the largest whales have body masses twentyfold those of a typical elephant, whale brains are barely twice the mass of an elephant's. A wide variety of behaviour, including those associated with grief, art, play, use of tools,[32] compassion and self-awareness [33] evidence a highly intelligent species on par with cetaceans and primates.[34]
The largest areas in elephant brain are those responsible for hearing, smell and movement coordination, and a large portion of the brain has to do with trunk management and sensitivity.
