Octopuses are highly intelligent and adaptable cephalopods known for their problem-solving skills, ability to escape predators, and sometimes remarkable use of tools. They are solitary predators that feed mainly at night, preying on a variety of marine species including crustaceans, mollusks, and fish. Octopuses have an array of defensive tactics including the release of ink, camouflage, and the ability to autotomize their limbs.
