👉 Actinozoa are a group of animals that have two arms and can breathe air. They belong to the order Actinopterygii, which is also known as the "fishes" or "vertebrates." These animals are characterized by their long, flexible tentacles that allow them to swim efficiently in water. They also have an operculum, a small membranous tube that connects each arm and allows for movement of the arms.
