This is the definitive Grey species classification article on the Think About It network — a detailed biological and tactical profile distinguishing between three primary Grey subtypes, their reptilian evolutionary origin, the 22 reported subspecies within the broader Grey taxonomy, and their operational relationship with the Draconian command hierarchy. Type A (Rigelian/Reticulan standard Grey): 3.5 to 4.5 feet, large black wrap-around eyes, grey skin, four-digit hands, the abduction-associated drone worker. Type B (Tall Grey): 6 to 7 feet, commanding role, often described as supervising Type A workers during abduction procedures. Type C (short Grey variant): approximately 3 feet, the most frequently encountered subtype, sometimes described as biological robot rather than autonomous being.

The article traces Grey evolutionary origins to a reptilian ancestor line — positioning the Greys not as a separate species from the Reptilians but as a derived branch of the same saurian evolutionary tree, genetically modified over millennia through cloning degradation until they became dependent on external DNA sources (primarily human) to sustain biological viability. The 1954 treaty framework, the abduction-for-DNA exchange program, and the Grey operational protocols during abduction events (paralysis beams, memory suppression, implant insertion, reproductive material extraction) are all documented. For anyone studying the Grey species category, this is the primary reference article.

The Greys

Small neo-sauroid race, very prolific and intelligent. May be the ‘brains’ or ‘intellect’ of the serpent race, whereas the larger ‘Reptoids’ allegedly act as the PHYSICAL overlords and thus are of a higher ‘ranking’ than the Greys. The Greys are reportedly very predatory and insensitive to humans, and like other reptilian entities they allegedly ‘feed’ off of human fluids by rubbing the ‘protein formula‘ on their bodies, which is then absorbed into the skin, and like snakes the ‘waste’ is excreted back through the skin.

The Greys range from 3 1/2 to 4 1/2 ft. tall on the average, with skin colors ranging from grayish white to grayish blue to grayish green. Aside from feeding off of human proteins and fluids, they also allegedly feed off the ‘life energy’, ‘vital essence’ or ‘soul energy’ of human as do other reptilian species. This is why those humans seen working with the Greys (implanted drones, whether willingly or unwillingly) have appeared ‘lifeless’ and emotionless to the witnesses who observed them. The

Greys are allegedly EXTREMELY deceitful and although they act on ‘logic’, to them it is ‘logical’ to use extremely complex forms of deception to bring about their goals. They are the most commonly observed ‘alien’ entity during UFO encounters

DATA

The approximate height is 3.5 to 4.5 feet tall. Some approximately 5 feet.
Their weight is approximately 40 pounds.
Two semi-rounded black eyes, without pupils. They are large, almond-shaped, elongated, sunken of deep set, far apart, slightly slanted, appearing ‘Oriental’ or “Mongoloid“.
The head, by human standards, is large when compared with the size of torso and limbs.
No ear lobes or protrusive flesh extending beyond apertures on each side of the head.
Nose is long and vague. Two nasal openings are indicated with only slight protuberances.
Mouth is indicated as a small “slit” without lips, opening into a small cavity-mouth, which appears not to function as means of communication or an orifice for food ingestion.
Neck described as being thin; and in some instances, not being visible because of garment on that section of the body.
The head is hairless.
The torso is small and thin.
Normally they wear a metallic but flexible garment
Arms are long and thin and reaching down to the knee section of the body.
The hands have four fingers each, but no thumb. Two fingers appear longer than the others on each hand. They have some kind of long fingernails. A slight webbing effect between each finger exists.
Legs are short and thin. Their feet are like an orangutans feet
They have no teeth.
Their skin description is some kind of beige, tan brown, or tannish or pinkish grey color. The texture as scaly or reptilian, and as stretchable, elastic or mobile over smooth muscle or skeletal tissue. No striated muscle. Light perspiration and very particular body odor. Under magnification the tissue of skin structure appears to be a mesh, or like a grid network of horizontal perpendicular lines. They suggest that the texture may be similar to that of the granular-skinned lizards, such as the Iguana and/or Chameleon, and may be similar to at least on other type of alien humanoid.

RIGELIAN

Type A

No apparent reproductive organs. Perhaps atrophied by evolutionary degeneration. No Genitalia The absence of sexual organs suggests a system of cloning reproduction may be prevalent.
The Aliens appear to be formed out of some sort of mold”, or sharing identical facial characteristics.
Colorless liquid prevalent in body, without red cells. No Lymphocytes. Not a carrier of oxygen. No food or water intake is evident or known at this time.
It is believed at present that no food may ever be required. No digestive system or Gl tract. No intestinal or elementary canal or Rectal area described.
Many variations of anatomy exist.
Their life span is unknown at this time.
One distinct species is mentioned again and again in stories about encounters with aliens. The descriptions of these beings are always strikingly similar: they have a grey skin, are usually about 4 foot tall (though smaller and taller versions have been encountered, too); they have huge black wraparound eyes, hardly any nose or mouth, and their sex is indistinguishable. Because of their grey skin, people started calling them “Greys.”

Research has indicated that most of these Greys come from either the Orion Constellation, or from the zeta stars of the Reticulum Rhomboidalis constellation. The Greys coming from Zeta Reticuli are usually referred to as the Zetas. Erroneously, in part of the UFO literature, ‘Zetas’ has been used as a synonym for ‘Greys,’ even though they are only one of several known species of Greys. (For more information on Zetas, see Zetas.)

Some believe that the US Government has a secret agreement with the Greys. According to the agreement, the US Government would allow people to be abducted on the condition that they would not be harmed, that they would be returned and that they would not remember the incident. In exchange, the US Government would get highly evolved technology. It is not clear whether this agreement was reached in 1954 (on Feb. 20, at Edwards AFB) or in 1964 (on April 24 or 25, at Holloman AFB).

Types of greys

The UFO literature usually distinguishes three kinds of greys:

Type A: Common Greys – approximately 4 feet tall,
Type B: Tall Greys – anywhere between 6 to 9 feet tall,
Type C: Smaller Greys – approximately 3 to 3.5 feet tall.
Recently, on the Internet, reports have appeared that describe Greys that are identical in appearance to the common Greys (Type A), but who are only 2 to 2.5 feet tall. Thus far, however, I have not come across any reports by researchers or abductees / contactees to confirm this.

Type A: COMMON GREYS.

This is the most common type. They are about four to four and a half foot tall, with large heads and wraparound eyes, a slit mouth and no visible nose.

In spite of the apparent physical similarities, the group of Type A Greys actually consists of several different species of Greys, that aren’t necessarily related, and that come from different parts of our Galaxy. The Zetas, e.g., come from the Reticulum constellation, and are believed to be of a humanoid descent, whereas other races, e.g. those coming from Draco, Orion and Ursa Maior, are believed to be reptilian species.

Type B: TALL GREYS.

Quite often the greys of Type A and Type C are accompanied by one or more greys of Type B: the Tall Greys. The Type B greys look very similar to the Type A greys, but they are a lot taller. Often abductees refer to these Tall Greys as ‘the doctor,’ because they seems to be in charge of the medical procedures taking place during the abduction event.

Two separate types of Tall Greys are known:

B1) the ‘large nosed’ tall greys, or the “Eban.” They are 6 to 9 feet tall and are believed to come from the Betelgeuse system in the Orion Constellation.

B2) the common tall greys: They are 6-7 feet tall, and are basically taller versions of type A or C, even though sometimes they are said to have reproductive organs. They also seem to have something that resembles a (small) nose. They are believed to come from the same constellations as the Type A and C greys.

TYPE C: SMALLER GREYS.

Sometimes people also mention greys of Type C. The Type C greys are the shortest, about three and a half foot tall. They are believed to be the most dangerous of all grey species. They come from Rigel (per J.D. Stone, V. Valerian) and Bellatrix in the Orion constellation, and are saurian / reptilian in nature.

OTHER GREY SPECIES

This classification in 3 types is a simplification of the actual situation. V. Valerian has done extensive research in these matters and distinguishes up to 22 different types of greys. Other Grey species that have been encountered too are, e.g.:
– The Orange (see: ‘Orange, The‘)
– The Bellatrix mercenaries: a genetic hybrid race between reptilian greys and insectoids, engineered solely for war-faring purposes.

Several sources also mention all kind of hybrid humanoid/Grey races.

It should be noted that not all authors are convinced that all Greys are extraterrestrials. John Mack, Jacques Vallee, Whitley Strieber and Graham Hancock, e.g., point at the similarities between the abduction realm and the realms of the fairies and the spirit world that shamans visit. They suggest that greys may be part of a parallel realm or another dimension that has always existed and that always had interaction with our reality.
It should also be noted that it is perfectly possible that if such realm exists, that extraterrestrials might use it to travel to Earth. This indeed is what Shamans all over the world claim. Shamans in Latin America and sangomas in Africa even make a clear distinction between the inhabitants of the other realm, and the aliens that use that realm to come and visit us.

Last but not least:

a) remote viewers who tried to discover where the greys are coming from mention that they are coming from three different time eras, i.e. that most of them are coming from different times in the future.
b) some authors believe Greys are not aliens but future humans or future humanoids.
c) some sources mention a “cyborg” type of grey: a small grey that seems to be partly biological (and presumably cloned) and partly mechanical. The remains of some of these would have been found at crash sites.

Type Name Height Origin Role/Notes
Type A Common Greys 4 – 4.5 ft Zeta Reticuli / Draco Most common; humanoid or reptilian descent.
Type B Tall Greys 6 – 9 ft Betelgeuse (Orion) The “Doctors”; often in charge of medical procedures.
Type C Small Greys 3.5 ft Rigel / Bellatrix Most dangerous; strictly saurian/reptilian nature.
Cyborg Drones 2 – 3 ft Unknown Part biological (cloned), part mechanical; crash site remains.

Type	Name	Height	Origin	Role/Notes

This comprehensive guide categorizes the Greys into three primary types (A, B, and C) while acknowledging up to 22 distinct variations identified by researchers like Valdamar Valerian. The text provides a detailed “Data Sheet” on their physiology—from their scale-like, “grid-network” skin and lack of digestive tracts to their “orangutan-like” feet and large, almond-shaped black eyes.

A central theme is the Secret Treaty of 1954/1964, suggesting a “quid pro quo” where the US Government traded human abduction rights for advanced technology. The profile also explores the metaphysical origins of the Greys, suggesting they may not just be from Zeta Reticuli or Orion, but could be time-traveling humans from the future or “interdimensional” beings that have co-existed with humanity as the “fairies” and “demons” of old ways.

Executive Summary:

The Greys — Types A, B, and C, Reptilian Origins, and the 22 Subspecies Taxonomy

This article provides the definitive Grey species classification: Type A (Rigelian/standard Grey, 3.5–4.5 ft, drone worker, abduction-associated), Type B (Tall Grey, 6–7 ft, supervisory command role), Type C (short variant, ~3 ft, possible biological robot). The Greys are traced to a reptilian evolutionary ancestor line, with their current form the product of millennia of cloning degradation that has rendered them dependent on external (primarily human) DNA for biological viability. Twenty-two subspecies within the broader Grey taxonomy are referenced.

Operational protocols documented include paralysis beams, memory suppression, implant insertion, and reproductive material extraction. The 1954 treaty framework and the abduction-for-DNA exchange program are detailed. The article positions the Greys within the Draconian command hierarchy as a derived saurian branch — not an independent species.

“The Greys are not a separate species from the Reptilians — they are what happens to a reptilian line after millennia of cloning degradation: stripped of reproductive capacity, dependent on harvested DNA, and reduced to drone function.”
