Definition
A 'giant crab' is a general term referring to exceptionally large crab species, most notably the Japanese spider crab ('Macrocheira kaempferi'). These crabs are known for their impressive size, with leg spans that can reach up to 12 feet, making them the largest arthropods in the world. They inhabit the deep waters around Japan and play a significant role in the marine ecosystem. Think of them as the redwood trees of the sea. π²
