Octopuses are smart

It has been found in a recent study that octopuses tip toe around the ocean floor colecting shells, which they later stack up to use as a fort to protect themselves from predators. "Using tools, something we think is very special about humans, exists in other animal groups we've never considered before," said Norman in an interview with Australian television. "A low-life form, a relative of a snail, these octopuses, they're not simple animals." Octopuses started out using smaller clam shells, but then moved up using larger shells and cocunut shells. According to science magazine cephalopods have the most complex brain of any invertebrate. It is very interesting to see how they are putting it to use.
