✦ Synopsis

Abstract

The pressures that drive blood in the circulatory systems of marine Crustacea are substantially higher than previously supposed. In recordings from the heart of nine species, absolute pressures (mean of systolic and diastolic) range from 6.7 cm‐H~2~O to 36.0 cm‐H~2~O. No relationship is apparent between blood pressure in these species and either wet weight or heart rate. It is proposed that the maintenance of high internal pressures may be of functional significance in Crustacea, both in urine formation by ultrafiltration and in molting.
