Abstract

The responses of an intertidal amphipod indicate an ability to perceive rapid pressure changes of less than 0.01 atm. The interaction of rate of change of pressure and total difference in pressure implies a rapid accommodation as well as a threshold. Evidence suggests that the sensory mechanism may not involve compressibility of a gas.
