5 amazing animals that learnt how to use tools
Chimps can adapt twigs to fish termites from their nests and absorb water to drink from narrow holes in trees. They also use rocks as weapons and to hammer open nuts. Some have even been seen crafting spears.

As revealed on Blue Planet II, this clever species of fish has worked out how to smash open clams on pieces of rock or hard coral in order to get to the juicy food within, a process that can take minutes or hour
