Cephalopoda

Cephalopoda is a class of marine animals that includes octopuses, squids, cuttlefish, and nautiluses. They are characterized by their soft bodies, tentacles, and advanced nervous systems. Cephalopods are known for their intelligence, ability to change color and texture for communication and camouflage, and their unique method of movement using jet propulsion. They lack an external shell, except for the nautilus, and possess a beak-like jaw. These creatures play vital roles in marine ecosystems and are known for their remarkable adaptability and problem-solving skills.
