The N'Kree are an aquatic species. N'Kree are fish-like amphibious humanoids with domed heads, webbed hands, and large eyes. Most N'Kree have salmon-colored skin, often mottled with light and dark patterns, though examples of other skin colors were known. They could also descend to depths of up to 30 meters below sea level without breathing, though they found it uncomfortable and often used organic gills. N'Kree could stay underwater for a long period of time, although a frightened N'Kree, particularly a juvenile, could drown underwater. They also did not need to decompress when resurfacing.
