Beyond the game
The real Eurypterus
Eurypterus remipes was an aquatic arthropod with a segmented body, grasping limbs and a broad pair of swimming paddles. The name sea scorpion does not make it a modern scorpion living underwater.
Its appendages performed different jobs, from handling food to swimming. A broad paddle-like pair gave this segmented aquatic arthropod a distinctive means of movement.
