The blood viscosity of arctic char, Salvelinus alpinus, and shorthorn sculpin, Myoxocephalus scorpius, from the arctic (74 degrees 42'N) was measured with a cone-plate viscometer. Blood viscosity of the two arctic species was considerably lower, less shear rate dependent, and less temperature depend

Abstract
The intrinsic viscosity of hemoglobin from the marine annelid Arenicola marina is less than 25% of the value predicted for a linear polymer of comparable molecular weight. The relatively low Viscosity, which appears to be related to the subunit arrangement in annelid hemoglobins, provides a much higher than predicted blood oxygen transport capacity.

The red blood cells of the annelid bloodworm Glycera dibranchiata contain two structurally and functionally distinct assemblages of hemoglobin. In the present sample the monomer comprised 57% and the polymer 43% of the total amount. The O2 affinities of the two differ by a factor of about two. There
## Abstract Blood viscosity and plasma protein concentrations were measured in 31 patients with a variety of visceral carcinomas. The mean whole blood viscosity was not elevated over normal controls because of a significantly lowered mean hematocrit. However, when hematocrit was eliminated as a va
