The Immortal Crustacean is one of the many fishes that can be acquired in the Frontier. The Immortal Crustacean can be found and acquired from The Long Coast's waters by extension.

The Immortal Crustacean can also be obtained as a possible reward from the Frog Quest.


The Immortal Crustacean is based on a Golden Ghost Crab and a Red Crab, crustaceans that can be found in real-life. Unlike its real-life counterpart, The Immortal Crustacean possess a golden armor set that protects its wrists, upper arms and legs, and its head from predators. Its lower legs, arms, and claws are unprotected and shows the actual colors of the crab, being red.

The Immortal Crustacean cannot be used in any shapes or forms, however, it can be consumed by the players in order to restore 200 HP back to their health pools. Other than that, it can be sold to a selling vendor at a selling price of 100,000 gold.


  • The Immortal Crustacean is one of the few collectibles in-game to possess high intelligence.
  • Despite having the word 'Immortal' in its name, it is still possible to eat it.
    • This may be due to the laws of immortality, where one never ages but can still perish in other ways like being consumed.
