Mirelurk

Mirelurks are creatures appearing in Fallout 3 and Fallout 4. They are giant, bipedal version of crabs that have been mutated by radiation.

General characteristics
Mirelurks Hunt you down. Based on information from the castle in Fallout 4 Mirelurks will disguise themselves as rocks then jump out and attack when you get close. They deal massive damage and can absorb a lot in return. Hatchlings can also sneak up on you while you are fighting the Mirelurk Queen.

Their design has changed from FO3 to FO4. They are now more crouched down and harder to hit.
