The drinking behaviour of elephants provides charming insights into the family lives of the largest land mammal on the planet.
Elephants choose to drink (and bathe) every day, although they can go several days without drinking. They use their immensely strong trunks as tools to drink with.
They also use their trunk to communicate with other family members as part of a greeting ceremony where a lower ranking elephant inserts its trunk tip into the mouth of the other. This ritual enables elephants to come closer together amicably.
