Both Classes W and T are telepathically camouflaged to appear as Greys to abductees. This point will undoubtedly be a source of much heated debate in the near future. Greys Of the six groups discussed in this paper, the Greys appear to represent the only non-human contingent. The following data should be considered tentative at best. Height is approximately five and a half feet.
Skin color is dark grey and non-porous.
All data so far indicates that they may be a cetacean-based life form. On Earth, this comprises the species of whales and dolphins. Descriptions of Greys' skin color and texture closely match that of dolphins. The stare and stun effects approximate that performed by dolphins on potential enemies, such as sharks and barracuda. Human and dolphin fetuses are nearly identical, up to a certain development stage.
