Octopus

Octopuses are marine mollusks belonging to the class Cephalopoda. They are known for their soft bodies, eight arms (covered in suckers), high intelligence, and remarkable ability to change skin color and texture. Octopuses inhabit oceans worldwide, from shallow reefs to the deep sea, using their camouflage abilities to blend in or communicate. They are carnivores, primarily feeding on crabs, shrimp, and fish. Octopuses exhibit problem-solving skills and can even use tools. When threatened, they can eject a cloud of ink to escape.
