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.

There are scientific studies that show that what we see as “simple” animals indeed show quite more intelligent behaviour. For example, fish have memory and can learn things. Lionfish hunt together, enclosing their prey with their pointy fins, and when caught divide it evenly among the participants of the hunt. As is the case with most animal species, the alpha male takes the largest share.

It is also discovered that ants in combat with other insects can and will save their wounded comrads on the battlefield, to increase their survival rate.

In short, animals often have special qualities that we rarely appreciate. We could deal with more respect with all the animals on earth.
