Tallon Crabs are quadrupedal crustaceans with two claws. One of their claws is much larger than the other, which is used for hunting and defensive maneuvers. Tallon Crabs generally travel in aggressive and dangerous swarms, though when isolated, they are timid and harmless. These creatures utilize similar tactics as Parasites, which also swarm for protection. These beings have an uncanny similarity to the crab depicted on the Spazer Beam upgrade, which may suggest that it held some symbolism within Chozo society before the Chozo race went extinct.
