Tintenfische, or octopuses, are marine animals known for their soft bodies and eight flexible arms. They belong to the class Cephalopoda, which also includes squids and cuttlefish. Tintenfische are highly intelligent and can change color and texture to blend into their surroundings, a skill that helps them avoid predators. These creatures are found in oceans worldwide, often in coral reefs and rocky areas. Tintenfische have a unique way of moving, using jet propulsion to swim quickly when threatened. They are also known for their ability to solve problems and use tools, showcasing their advanced cognitive abilities.
