Elephants are known for their extraordinary memories, but is it true that they never forget?
They say"an elephant never forgets." But how much truth is there to that expression? How good is an elephant's memory?
Elephants are not the only animals that forage for food in the savanna, but the unique challenges these pachyderms face demand exquisite memories. For instance, each elephant needs to eat about 330 pounds of vegetation each day, and to satisfy their voracious appetites, elephants embark on long migration routes between the wet and dry seasons. Whether they survive that migration depends heavily on their knowledge of the route.
Elephants also need their memories to navigate what biologists call a"fission-fusion" dynamic. In this arrangement, also common among primates and some whale species, a core family unit of elephants comes into contact with hundreds of other elephants over the course of the year , only to later break off into the same core group .
