Nukalurk

Nukalurks are a rare type of mirelurk (only 10 exist in the game, and they do not respawn), resembling the mirelurk hunter, as they both have the same anterior vestigial limbs. They are oddly colored, having a dark blue exoskeleton stippled with glowing blue features. This coloration is probably due to exposure and/or consumption of the radioactive Strontium isotope used to color Nuka-Cola Quantum.

Consumption of nukalurk meat provides a larger health boost than regular mirelurk meat and additionally boosts AP (probably due to Nuka-Cola Quantum's isotope), but is slightly more radioactive. Though slightly harder to defeat than regular mirelurks, their population is very small compared to other members of the species. It appears that the nukalurks have some sort of class system similar to the regular mirelurk. Specifically, the taller nukalurks are more powerful and vicious, similar to the mirelurk hunter, whereas the smaller ones appear to be more docile.

Appearances
Nukalurks only appear in Fallout 3.

Bugs

 * If you kill nukalurks in the Nuka-Cola Quantum pool, sometimes they will sink under the floor and disappear. However they can be looted before this occurs if you're quick about it. An easy way to solve this is to lure them out of the pool and kill them once they are far enough away from the pool that they won't fall back in.
 * Most of the time, Nukalurks with no nukalurk meat will fall into the ground.


 * If you kill a nukalurk in the Nuka-Cola Quantum pool, it may glitch causing it to twitch and spray water around. This has no effect on gameplay, and is only visual.


 * While traveling through the mixing vats, firing at the last nukalurk from the broken railing (right side from the door leaving the glowing pools) before entering the offices can cause the nukalurk to warp direcly next to the player, startling the player. However after the warp the nukalurk may or may not continue to come after the player, it still remains hostile though


 * The first nukalurk in the pool may disappear until it is shot or the player is extremely close, however its red marker still shows up, making it easy to find.


 * At random moments, a Nukalurk may fall through the ceiling into the ground and back again.
