Octopuses are mollusks known for their unique appearance and intelligent behavior. Octopuses have eight equal-length tentacles, each covered with suction cups that help them grip objects and move underwater. Octopuses are considered one of the most intelligent invertebrates in the ocean. They are able to solve problems, learn, memorize, and even use tools. Octopuses are usually solitary creatures that hunt and live alone, with little contact with other octopuses except during mating. When faced with a threat, octopuses spray ink to confuse predators while quickly fleeing. Come and color these cute octopuses in rich colors.
