Do elephants really never forget?
An elephant has a very large brain for its size and the ‘temporal lobe’ region responsible for memory is more developed with a greater number of folds – this results in powerful abilities to ‘download’ important survival data such as where to find food and water, and who is friend or foe. The matriarch of a herd (who can live for 60 years) may recognise over 200 individual elephants and can react to the call of a deceased member of her herd two years after their death. During droughts, these grandma elephants lead family members to waterholes by recalling detailed maps they’ve made spanning hundreds of kilometres. So although they undoubtedly forget what they don’t need to remember, they appear to remember what they cannot afford to forget!
