👉 Powelliphanta is a type of cephalopod that has two arms, which are not typically considered by most experts in the field. It is characterized by its distinctive, spiral-shaped arms and the presence of a unique shell-like structure called a "hook." This hook can be used to grasp onto objects or to transport itself through water. The term comes from the Latin word "powellus," meaning "spider" in Greek.
