The elephant trunk, a specialized nose, is analogous to an octopus tentacle in terms of dexterity. It allows them a high degree of manipulation of objects and elephants are adept tool-users. Elephants have been taught to paint with their adroit trunks and produce some fascinating artwork. In captivity, elephants easily learn how to open simple locks and many master more complex ones, something impossible for most other animals due to a lack of dexterity and intellect.
Elephants in zoos have worked together to take advantage of this, by having many act as lookouts as another undoes the lock, or in one instance an elephant feigned injury as a distraction while another elephant helped the others escape. Once all the elephants were out, the distraction elephant climbed to its feet and ran for the door, surprising its tenders who had been unaware of the ruse.
