The Octopus is a mollusk belonging to the class Cephalopoda. All 300 species have no skeleton, allowing them to squeeze into and hide in tight spaces. When they get caught off guard they might release ink to cloud the water and allow for an escape. They are known for their eight arms lined with suction cups and large bulbous heads. Octopus are considered the most intelligent of all invertebrates. Scientists have proven their high-intelligence by having the creatures solve puzzles and mazes. along with other challenging tests. I find this animal to be absolutely fascinating and among my most favorite, in nature and in my art!
