Limnologist Frey has discovered evidence of this in an increasing population of the red "blood" midge, a mosquitolike larva that can get along fine on far less oxygen than its more demanding green and brown brothers. In Douglas Lake, Frey's crew also brought up a few "phantom" midges, near-transparent larvae that can reach adult stage without any oxygen at all for long periods at a time...
