A fascinating clip from the 2017 BBC Documentary Wild Thailand shows how Macaque monkeys who live by the sea have adapted to their environment by cleverly employing tools, specifically rocks to break open the tough shells of the seafood that becomes accessible to them during low tide.
The shells are hard to crack, but ever-resourceful, these macaques have found a smart solution. They’ve worked out that rocks make perfect shellfish hammers.
Of course, living by the sea has other benefits, of which the monkeys take full advantage.
