Mirelurks are mutated and blue crabs living in the in .

[] Characteristics

[] Biology

Mirelurks are descended from Chesapeake Bay . The full scientific classification of the mirelurks is kingdom: Animalia, phylum: Arthropodia, subphylum: Crustacean/Chelicerata, class: Merostomata/Malacostraca, while order, family, and genus are left undetermined due to their mutation. The subphylum and class are disputed in an officer's field research terminal, as he believes horseshoe crabs and blue crabs both evolved into mirelurks, due to their DNA/RNA samples having markers from two different subphyla and classes. Furthermore, he and the player both fill in the missing order, family, and genus with the same answers (on the terminal, and in a dialogue check after completing the mirelurk portion of quest): Scylla serrata horrendus.

Mirelurks are always found in damp and aquatic areas such as the mouth of the river Potomac and the river itself. If not in an aquatic habitat, mirelurks have been seen in dark, cool areas, like caves, metro tunnels, and derelict facilities that fit the description, like the . However, mirelurks do not reproach from light; they can be seen during the day, swimming in rivers and walking along the banks. This is especially true around , the Potomac and the Anchorage War Memorial.

[] Gameplay attributes

All mirelurks, except for mirelurk kings, are surrounded by a thick shell which is difficult to penetrate, even with powerful ballistic weapons such as the . Their only weak spot is the face, but the area is small and difficult to hit. When charging, mirelurks will lower their head to protect this area. However, they will swing their heads up during the attack animation, exposing their faces. The utilization of V.A.T.S. and an accurate weapon, such as a rifle, can be helpful. Low level players will find mirelurks to be among their deadliest enemies.

Mirelurks are extremely territorial, so if anything trespasses, they will attack it until it is dead. Even if the trespasser makes a run for it, the mirelurk will still pursue them ferociously until the trespasser is run down. Often mirelurks leave combat to go and get support from other mirelurks.

, especially the , is highly nutritious and grants some of the highest HP replenishment of any food in the game. This is reinforced by , as she will tell the player that mirelurk meat is "the best meat in the wastes". Both are slightly radioactive, but no more than typical food. Chefs throughout the wasteland have developed many culinary uses for mirelurk; the most prominent being the creation of . In fact, a for them can be found in a fridge in the Anchorage War Memorial.

[] Mirelurk

The most common type of mirelurks have a whitish-grey shell, are about a head shorter than a normal human, and walk slightly slower than a human. Mirelurks fight with their claws and lack ranged attacks.

Additionally, at close range they can charge forward in a brief burst of speed for a headbutt, which also makes it impossible to target their face. However, their face is most vulnerable in the seconds after a headbutt, when their 'head' is raised.

[] Mirelurk hunter

A much larger, reddish-brown colored version of mirelurk. In addition to their two main arms, hunters also have two pairs of small, segmented vestigial appendages growing out of their chest which they may attack with, but very rarely. Mirelurk hunters inhabit the Potomac River in the northern wastes and several sewers and caves near the metropolitan area of the Capital, along with a good number in the Anchorage War Memorial. Hunters are very aggressive and are more difficult to kill due to their increased Strength, speed, and health. They appear more frequently at later levels. Their powerful pincers inflict heavy damage and can knock back low level characters easily.

[] Mirelurk king

Mirelurk kings are different from other mirelurk variants, mainly because they do not resemble their crab-like "subjects". They are not crabs, but are mutated snapping turtles that appear more humanoid and do not have a heavily armored carapace, making them easy to distinguish from standard mirelurks. They are possibly a separate species in a symbiotic relationship with the crab-like mirelurks. These too appear more frequently at later levels.

Mirelurk kings have a sonic projectile attack that disregards and causes lots of limb damage to the subject's head, crippling it.

Unlike mirelurks and mirelurk hunters, they cannot float in water.

[] Nukalurk

A mirelurk hunter variation that can only be found in the . They are oddly colored, having a dark blue exoskeleton stippled with glowing blue features along certain regions of their bodies. This coloration is probably due to prolonged exposure and/or consumption of the radioactive Strontium isotope that was used to color before the . Interestingly, Nukalurks appear in both "regular" and "hunter" versions like their mirelurk cousins, yet there is no difference between the two versions besides their size and appearance.

Their is notable for a small boost in AP as well as radiation and health; 4 rads, +10 AP, and +20 HP. However, only 10 nukalurks appear in-game, limiting the amount of meat available to no more than 10.

[] Swamplurk

Swamplurks (designated "mirelurk" in-game) are a variation of mirelurk which inhabit the swamps of . They are visually identical to mirelurk hunters except for their size, their green-tinged shells due to the swampy environment and the lack of vestigial limbs on their abdomen.

[] Swamplurk queen

Swamplurk queens (simply called swamplurk in-game) are a variation of the Capital Wasteland's mirelurk kings that inhabit the swamps of . Like the mirelurk kings, they are mutated from snapping turtles native to local rivers. They look extremely similar to kings, distinguishing traits being a mossy coloration and strangely shimmery glowing yellow eyes.

Unlike mirelurk kings, the swamplurk queen spits acid from its mouth, similar to a . Although not radioactive, this acid is highly damaging.

Strangely, even with its lack of clothing, the swamplurk queen can be pickpocketed, allowing for the player to reverse pickpocket explosives for an easy kill, if they can get close enough with a sneak. However, this results in a negative karma.

[] Notes

  • Mirelurks are unable to attack while swimming, rendering them as helpless as other swimming land creatures, despite their aquatic origins. The mirelurk king's sonic attack can injure the player while underwater when shot at from land. This can effectively make the player a sitting duck while in the water, since the player has no means of fighting back.
  • Mirelurks seem to ignore any and every weapon's "stopping power." Even a missile or Gauss rifle bolt to the face will not faze them or slow them down while they charge towards the player. and appear to repel them to some extent, but this is more likely due to their attack animations which tend to "push" things away.
  • A can be found burning a dead mirelurk with a outside of after it becomes operational. He notes that the mirelurks are dying in the new pure water and appear to survive solely in radioactive water. He also notes that they smell rather bad. There is also a Brotherhood of Steel Knight patrolling the catwalks, who comments on how they are encouraged to take potshots at the dying mirelurks.
    • Despite this, the mirelurks that re-spawn in the tidal basin do not actually die by swimming in the water, though they spawn with greatly diminished health, allowing the Brotherhood or the player to easily kill them. Over time, however, they wear down the Brotherhood members who fight them and kill them or cause crippling injuries.
  • Mirelurk make a loud, distinctive clicking noise, which will easily give away their presence.
  • At lower levels, mirelurks can be rather dangerous when first entering DC or any of the caves/lairs they inhabit.
  • As seen in , seems to kill them, a rather easy solution to an otherwise difficult enemy.
  • Although nukalurks are filled with the isotope for Nuka-Cola Quantum, they can't inflict radiation on the player, despite the fact that the isotope itself is radioactive.
  • It appears that the mirelurk king is later used in Fallout: New Vegas, where it looks the same, but is given the name .

[] Behind the scenes

  • is the binomial for the common mud crab, not the mirelurks .
  • A mire is a tract or area of wet, swampy ground, bog or marsh. So the mirelurks' name is fitting, as they tend to lurk in mires.
  • The mirelurk kings and Lakelurks are similar in appearance to the creature from .
  • Early in the development of Fallout 3, when undetected, Mirelurks would crouch down and fold their limbs under their shell to avoid view, making predators merely view them as a rock. When anything came closer, they would slowly stand up.

[] Bugs

  • PCIcon pc.png PlayStation 3Icon ps3.png Xbox 360Icon xbox360.png Mirelurks killed in water will often flip over on their fronts and twitch. This is purely a graphical glitch related to their wireframe. Sometimes they will twitch so much they fall right through the floor, or become trapped in walls and doors while constantly playing a collision noise that can alert other enemies.
  • PCIcon pc.png PlayStation 3Icon ps3.png Sometimes when mirelurks are killed on land, body parts will sink into the textures on the floor, as much as half their body, and the remaining parts will flail and bounce.
  • Xbox 360Icon xbox360.png If you have a follower in the water as a mirelurk swims by he/she will get stuck on the mirelurk.
