Mole rat

Mole rats are giant rodents that have become mutated after the Great War.

Despite the fact that they have the same name, two species can be distinguished. The mole rats found on the Core Region are mostly covered with fur and come from moles, and those from the East Coast and the Mojave Wasteland are furless and come from naked mole rats which come mostly from governmental experiments rather than the area, as mole rats are not native to the United States of America.

Origins
On the "Pentagon Library terminal" in the Citadel, it can be discovered that the mole rats in the Capital Wasteland (and possibly the other mutated rats in the west coast and the Core Region) are the result of an American government program (codenamed 'CLOACINA') to develop an invasive lifeform that could be planted in China, where its aggression and fast breeding would help undermine the Chinese war effort. It is noted that a genetic 'kill switch' was included to help the US Army clean up the rats after the theoretical fall of China. Additionally, it is revealed that the researchers attempted to use the Forced Evolutionary Virus to further augment their creations, but dismissed this course of action as FEV had a tendency to render subjects sterile (defeating the whole purpose of the rats' being invasive).

Biology
An Enclave field report in Fallout 3 classifies naked mole rats as follows:
 * Kingdom: Animalia
 * Phylum: Chordata
 * Class: Mammalia
 * Order: Rodentia
 * Family: Bathyergidae

According to the report, naked mole rats most closely resemble a Heterocephalus glaber, also known as the sand puppy or desert mole rats. Their enlargement is due to heavy radiation exposure. While larger than their ancestors, the naked mole rats have similarly low brain function, possibly due to an exceedingly tiny brain organ. Their incisors show increased enamel and dentin growth, making them razor sharp. In addition, the naked mole rats have extremely low levels of Substance P which results in an incredible pain tolerance.

Hairy mole rat


A mutated mole only found in the Core Region. They can often be found in packs together with pig rats and giant rats.

Hairy albino mole rat


A rare variety of intelligent hairy albino mole rat only found in Core Region. Their origins are unknown but like albino deathclaw, appears to be caused due to a different mutation with the FEV.

They're a bit bigger than a normal hairy mole rat, have a light brown hair and red eyes. They can talk and have a relatively higher intelligence than the average. The only two known specimens are Keeng Ra'at and Brain.

Naked mole rat


A mutated naked mole rat found in East Coast and the Mojave Wasteland. They have very little hair on their body and are usually found in packs of roughly 3 or 4, but rarely in 2 or by themselves.

Naked mole rat pup


These are young naked mole rats and are smaller and weaker in combat. They usually stay close to their mother.

Appearances
Mole rats appear in Fallout, Fallout 2, Fallout 3 and Fallout: New Vegas. They were going to appear in the canceled Fallout: Brotherhood of Steel 2.
