The octopus is a marine animal known for its soft body and eight long arms, which are lined with sensitive suckers. These creatures belong to the class Cephalopoda, which also includes squid and cuttlefish. Octopuses are highly intelligent and can solve problems, use tools, and exhibit complex behaviors. They are found in various ocean habitats, from coral reefs to deep-sea environments. Octopuses have a unique ability to change color and texture, allowing them to blend into their surroundings for camouflage. They are also known for their remarkable escape skills, often slipping through small openings. When threatened, an octopus can release a cloud of ink to confuse predators and make a quick getaway.
