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 typically travel in aggressive swarms, though they are timid and harmless when isolated. These creatures utilize similar tactics as Parasites, which also swarm for protection. The Tallon Crab also appears to be depicted in the item form of the Spazer Beam upgrade, suggesting that the crab may held some significance within Chozo society.

During her mission on Tallon IV, Samus Aran encountered a swarm of Tallon Crabs in the Main Ventilation Shaft Section A of the crashed Space Pirate frigate Orpheon, which was submerged in the planet’s Tallon Overworld region. As suggested by the scan data collected of them, they appeared to be corrupted by Phazon exposure from Phazon present at the time of the Leviathan impact.

Official dataEdit


"Tallon Crabs generally travel in huge swarms. When isolated, individual crabs are timid and harmless. Tallon Crab swarms, though, are extremely dangerous. It is possible for a hungry mass of crabs to consume a much larger lifeform in a matter of seconds.

The Tallon Crab is a quadruped crustacean with two claws. The much-larger primary claw is used for hunting and defensive manners."

Logbook entry

Hard-shelled swarm life-form. Once harvested for food, exposure to Phazon has seen this practice diminish. Creatures are timid and harmless alone, but can be a problem when traveling in swarms.


  • This species may be related to the Sciser, as both are crab-like organisms which appear to possess three eyes.
  • Unusually, Tallon crabs do not have a heat signature when viewed through the Thermal Visor.
