Antarctic fishes: experiments of nature which demonstrate the fundamental importance of blood viscosity

Viscosity increases with decreased temperature. The author argues that loss of hemoglobin is a “disaptation” or evolutionary loss of function which confers a competitive advantage in Antarctic waters because of decreased blood viscosity. Because the likelihood of developing turbulent flow is inverse...
