Direct measurement of the volume changes of planktonic euphausids and intertidal isopods, due to pressure changes of a few atmospheres, indicated specific compressibilities of the animal tissues from 15 to 40% lower than the compressibility of seawater. Similar measurements on an intertidal amphipod provide no support for the hypothesis that the sensory system by which these animals perceive small pressure changes is based on an ultrathin layer of gas.
