Krites (also known as "Critters") are a ferocious extraterrestial species. Egg laying creatures, Krite embryos incubate in their eggs for a period of six months, however the incubation period can be prolonged by reduced temperatures, causing the embryo to stay in stasis for periods of up to two years before hatching. A Krite egg is approximately 15 cm in height, being of an oval shape. Coloration of eggs can vary from brown, to brown with light green mottling, to a metallic dark green. Eggs have a hard outer shell like that of a birds, and are covered in an irregular pattern of raised interconnecting plates. A thick, sticky light green amniotic fluid fills the eggs, protecting the embryo Krites from minor collisions during early development.
