Mi-Go

Physical Characteristics
"...Crustaceous bodies bearing vast pairs of dorsal fins or membraneous wings and several sets of articulate limbs, and with a sort of convoluted ellipsoid, covered with multitudes of very short antennae, where a head would ordinarily be." - H.P. Lovecraft

The mi-go, or "fungi from yuggoth", are pinkish fungoid crustaceon-like organisms with wide, fan-like wings. It has six main limbs and a wrinkled head which can change color. The fungi communicate by rapidly changing the color of their heads, and project multicolored beams of light to communicate over long distances. Their are many subspecies of mi-go, and they all cooperate without difficulty. They skilled at body modification, often altering organs and body structures on a whim. Their mentality is very different from humanity's, and it is nearly impossible for humans to understand these creatures.

History on earth
The mi-go arrived on earth during the Jurassic period, fighting off attacks from the Elder Things and eventually settling in the northern hemisphere. They have gradually lost terrain, and today they inhabit the Andes, Himilayas, and Appalachians.

Behind the scenes

 * Mi-go control a vast interstellar empire, yuggoth (which seems to be pluto) being the largest base closest to earth.
 * Mi-go are not composed of ordinary matter, and can alter their bodies through prolonged effort. This, rather than ordinary evolution, may explain the many subspecies.
