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...

Viscosity increases with decreased temperature.

Because the likelihood of developing turbulent flow is inversely related to viscosity, a minimum degree of blood viscosity is necessary.
