Mirelurk (Fallout 3)

The Mirelurks are a species of bipedal, mutant crabs from the Capital Wasteland area. Most Mirelurks are surrounded by a thick armor/shell which is difficult to penetrate. However, their face is vulnerable and is the best area to attack.

It is possible to obtain the meat of Mirelurk hatchlings, which gives a boost to health, but also increases the radiation level slightly.

Appearances
Mirelurks appear only in Fallout 3

Types of Mirelurks
Mirelurks: The Most Common type of Mirelurk. Found in most low-level outdoor and indoor water sources. Drop standard Mirelurk Meat.

Mirelurk Hunters: A larger, red-colored version of the Mirelurk. Mirelurk Hunters inhabit the Northern Wastes and several sewers and caves near the Metropolitan area of the Capital. Drop softshell Mirelurk Meat, which gives more HP at a less Radiation increase than normal Mirelurk Meat.

Mirelurk Kings: A Mirelurk sized relative to the Mirelurk Hunter, but with a resemblance to the creature from the black lagoon. Mirelurk Kings are easy to spot, and easier to kill (due to their lack of armor) than Mirelurk Hunters. Kings are only found in a few caves in the Capital Wasteland and do not present any other special loot or items over Mirelurk Hunters. The first encouter will probably happen in the quest Agatha's Song as they infest the reactor part of Vault 92.

NukaLurks: A glowing blue Mirelurk that is only found (I've killed 4 of them) in the Nuka-Cola Factory, almost certainly due to the isotope used for Nuka-Cola Quantum. Their meat is notable for a small boost in AP as well as Radiation and Health.
