The Grigari are a humanoid species. Grigari are distinctively known for a bifurcating (cartilaginous) ridge running vertically along the center of the head and face, and half-way down their chest. Skin color ranges from blue-gray to vivid blue, and is occasionally accented with dark blue bands on their head although some of their skin is pink. Grigari males are completely bald and are on average as tall as the average Human male, and are not known for their physical prowess. Grigari females are sometimes completely bald, and sometimes have hair. Male Grigari have been known to wear toupees on occasion. In addition to the ridge on their heads, they are also noted for having cartilaginous lining on their tongues that allows them to consume foods not normally palatable by other Federation races, including strong acids. One such example of traditional Grigari cuisine is the consumption of meat that had been allowed to partially decay. When removed from the body, Grigari blood is blue in color.
