Fog crawlers are mutated saltwater crustaceans in the Fallout 4 add-on Far Harbor and Fallout 76.

Biology

Fog crawlers are large, mutated crustaceans, named for their presence in foggy or cloudy coastal regions and islands, where they use the environment to hunt.[1] The Far Harbor fog crawlers are the result of the radioactive fog altering the local shrimp population.[2] The exact species from which fog crawlers mutated is not immediately apparent, but they are most likely a form of mutated mantis shrimp (specifically the Squilla mantis) based on the anatomy of their forelimbs and the presence of a distinctive neck which most crustaceans lack. Another potential candidate is the crayfish.

The different types of tail "fans" on different types of fog crawlers could determine their gender, as crayfish carry eggs under the tails or as courtship during mating to avoid injury. The smaller legs (swimmerets) on the underside of the fog crawler are a holdover from when it remained an aquatic creature, assuming it isn't still largely amphibious. It seems that at some point the creature's head had evolved a mobile neck similar to terrestrial insects, as well as morphed into a kind of arrowhead shape. They seem to have eight eyes, four in a straight line on each side of the head, with the one second from the front being the largest. They also seem to lack any sort of visible mouth.

They live in the deep Fog for which they are named, and are seldom encountered outside the island's deadly mist.[2] Fog crawlers are known to make deep, booming vocalizations as an indicator of their presence. They are also among the strongest and most tenacious foes encountered in their respective areas, combining excellent protection with a generous health pool and the ability to attack at range.

Behind the scenes

FB8 deco 301 color.pngThe following is based on unverified behind the scenes information and may be inaccurate.
  • The fog crawler largely resembles one of the older concepts of the mirelurk queen.
  • The fog crawler could be an allusion to the arachni-lobster creature from Stephen King's novella The Mist. The similarities include a mysterious crustacean, which dwells in an unnatural fog.

  1. Creatures: Fog Crawler: "Fog crawlers are aptly named. They inhabit coastal regions and islands, predominantly with low cloud and fog banks that they use to hunt. Their crawling, shambling gait when not enraged lets them move through the surf or into woods with ease, but swiftly accelerate to pounce on prey and enemies. Woe betide the unwary hunter who thinks they are safe because of the Fog Crawler’s apparent grazing; their explosive bouts of speed will put them in danger before they have time to realise the threat.
    These monsters tend to be solitary beasts, stalking isolated but verdant regions as apex predators. Even the mighty Deathclaw keeps its distance. The Fog Crawler’s speed and dexterity mean it is more than a match for anything in its path, leaping and slashing at what will soon become its next meal…"
