Sad image of a mother elephant carrying her baby elephant that died due to illness.

This is a normal behavior in elephants, the mother elephant will use her trunk to carry the lost baby elephant when she was very young to follow the herd everywhere, until the baby elephant begins to decompose, the mother will stop mourning.
Elephants are very intelligent, they always care about other members of the herd, especially baby elephants. They often make visits to the site where a previous member of the flock died. Elephants will use their trunks to smell and touch the deceased member's land to pay tribute.
Elephants have very good memory, they can remember all the long roads they have passed in their lives. Where there is water, where there is food, elephants will remember and pass it on to their descendants.
Similar behavior occurs in baboons, who also show love and are very sad if their young are unfortunately killed.
