Artemia monica is endemic to Mono lake, where it tolerates both the alkaline and hypersaline environments. It occurs in vast numbers (an estimated 5 trillion inhabit the lake). They vary in color from russet to vernal - mostly seeming to be a result of what they have recently eaten. A young individual is included in this image.
