Mirelurk

Mirelurks are creatures appearing in Fallout 3 and Fallout 4. They are giant, radiation-mutated crustaceans.

General characteristics
In Fallout 3, Mirelurks are mutated horseshoe crabs. Mirelurks are often ambush predators that will disguise themselves as rocks, then jump out and attack when prey gets close. They can deal massive damage and can absorb a great deal in return. Hatchlings are shown to be highly aggressive, as egg clutches will often have at least one or two hatch and proceed to attack the intruder.

In Fallout 4, Mirelurks appear much more crab-like in appearance than those in Fallout 3, and their posture is generally crouched down to make their vulnerable faces harder to hit. Their shells also possess a mild reflective quality, as lasers are often seen ricocheting off them. The Mirelurk Queen displays a pronounced lobster tail.
