Maybe animals are smarter than we think. For example when we have to crack a nut we use a nutcracker, but animals don't have things like that so they have to improvise. The sea otter does.
A group of scientist including myself have went to study the sea otter and how they function without the advantages we have. Sea otters snack on a sea snail called abalone. But the abalones shell if very hard and often not easy to break. We spotted a sea otter one day and it was laying flat on its back with a rock in one hand and a abalone on its belly. The otter began beating the abalone and cracked the shell and was able to feast. Our conclusion was, animals can improvise and they have the brains to find out how to function without tools.
