Mirelurk (Fallout 4)

Mirelurks are creatures ecountered in the Commonwealth in Fallout 4.

Characteristics
An aquatic creature that appears in Fallout 4. This specimen in particular resembles a mirelurk hunter, but also differs in several aspects, such as seen with their legs. This specimen also walks in a mixed crab/spider-like motion, which is atypical of mirelurk variants documented so far. Of course, this may be a kind of "reboot" of the mirelurk's design, in an attempt to make them look more crab-like. Mirelurks also appear to deal radiation when killed in close quarters.

Mirelurks will bury themselves in dirt or mud, with the only visual indication that they are present being the rounded backs of their shells, which resemble large, smooth rocks from a distance. VATS will be able to spot them from a distance when used.

Mirelurk hatchling
When approaching a mirelurk nest, attacking or stealing mirelurk eggs will force nearby eggs to hatch prematurely, revealing these small crab like creatures.

Legendary mirelurk
The legendary mirelurk can spawn in place of a softshell mirelurk as part of the Thicket Quarry questline, "Pull the Plug".

Mirelurk killclaw
Powerful mirelurks, which stands by their "legendary killclaw" at Cutler Bend.

Mirelurk queen


The mirelurk queen is a new mirelurk variant. The queen is considerably larger and more dangerous than her children and inflicts more radiation on the player character. One occupies The Castle and is fought when the Minutemen retake it and another occupies the Murkwater construction site. The mirelurk queen's acidic spittle rapidly damages anyone caught in it and she can spawn new hatchlings. She is also incredibly durable; it can take up to three shots from the Fat Man to kill her.
