Did you know that fish use tools?

Everyone knows that monkeys use stones to crack nuts. It is very cute to see a young monkey trying to learn the trick. It is also known that birds pick up shellfish and drop them from great heights to break the shell and eat the animal.

Now the makers of The Blue Planet II have filmed a fish that takes a shellfish from outside the reef, goes back into its own territory and then hits the shell against a rock to break it. It is not easy at all without hands. It is the first time that a fish has been seen using a tool.

The series; The Blue Planet II can be seen on BBC. It is a very beautiful series, see and enjoy how beautiful the world is under water. In another episode they found corals that live at great depths in the ocean.
