The term 'Ten-Armed Swimmer' is a reference to the SQUID, an aquatic creature with ten arms. Squids are cephalopods, meaning they have a distinct head and foot, and are found in many of the world's oceans. They are known for their ability to rapidly propel themselves through the water using jet propulsion. Squids are also known for their intelligence and complex behavior, making them a popular subject of study for marine biologists.
