How big is a giant sea spider?

Giant sea Spiders, belonging to the class Pycnogonida, can vary significantly in size, with some species having leg spans that exceed 3 feet (about 1 meter). Their bodies can be relatively small, often measuring just a few inches, but their long legs make them appear much larger. These intriguing creatures are typically found in deep ocean waters, where they feed on soft-bodied invertebrates.
