BBC wildlife contributor Kate Evans lets us in on a little known, and certainly adorable, fun fact about elephants.
As in all young mammals, an elephant calf's sucking reflex is strong. And when a youngster is not feeding, it may suck its trunk for comfort, just as a human baby would suck its thumb.
Newborn elephants have little control over their trunks and must learn how to use them. They practice by exploring their environment - touching fellow herd members, their surroundings and themselves. They must then master the use of their trunks for feeding. With more than 50,000 individual muscle units in the trunk, it's a complex skill to learn.
This hilarious video demonstrates the struggles of mastering the trunk.
Though trunk-sucking is more common in the early stages of life, elephants of all ages do it, even big old bulls, usually when they are feeling nervous or unsure!...
