Elephants understand the concept of co-operation and can see when a task requires teamwork, according to researchers.
In an oversized experimental set-up, scientists observed elephants as they worked out how to work together to pull a table of food rewards towards them.
To move the table, the two elephants had to pull on either end of a rope.
Their ability to understand this need to co-operate, evident from this footage, puts elephants in what the scientists described as an "elite group" of intelligent and socially complex animals.
