Saurian (Star Trek)

Saurians are a spacefaring humanoid reptilianoid species and one of the member races of the United Federation of Planets in the 23rd century.

Biology
Saurians are fairly similar to Earth lizards in ways such as scaly skin and oviparous means of gestation, they evolved in an environment with five times the gravity of a standard M-Class planet. they have a mostly humanoid body type except for the fact they have either yellow or black eyes with vertical and horizontal eyelids, and six nasal passages which causes much discomfort when infected with diseases such as the common cold, they are believed to share a common ancestor with the Gorn going back at least ten thousand years, they shed their skin yearly and they have skin tones such as smooth red, brown, green, grey, pink and purple.

Saurians possess four hearts, which initially beat each in a different rhythm but as they age and reach the prime of their lives, they synchronize and beat as one.
