An intelligent alien species generally believed to be from the Zeta Reticuli star system. They are described as small, thin humanoids with hairless grey skin, disproportionately large heads and enormous black eyes which may actually be some sort of synthetic covering that protects the creatures real eyes.

The mouth is small, thin lipped or lipless, and toothless. The nose is either very small or non-existent except for nostrils. The ears are nothing more than an opening or slight indentation (no ear flap). External genitalia is non-existent as are facial expressions, and visible emotions of any kind.

The greys may be an ancient race that evolved on another planet from a dolphin-like ancestor or they may be humans from a very distant future. In any case it is believed that they have evolved over millions of years into a sexless race that can only reproduce by cloning. Some or all of them may be partly or wholly mechanical.

They may have telepathic abilities or some other ability that allows their communications to go undetected by humans. They may be working closely with one or more of Earth's governments, and they are believed to be the aliens responsible for most unexplained cattle mutilations.

Greys are also responsible for the vast majority of human abductions. Humans are abducted and used in DNA and reproductive experiments and other medical studies including the creation of alien/human hybrids.

At this time there is no known method to prevent alien abduction, however, talk therapy and medication may alleviate some symptoms. Call your doctor or local hospital for a referral to a licensed therapist or support group. Symptoms of alien abduction as well as other types of aliens that abduct can be found under "Aliens" below.

Also known as Zetas, Reticulians, Grays, or The Visitors.
