Summary
The angular acceleration receptor system of the statocyst ofOctopus vulgaris can be classified morphologically into two sub-systems on the basis of cupula form and size8. Electrophysiological experiments demonstrate that these two subsystems differ in their sensitivity ranges; one is appropriate for the detection of low and the other for the detection of higher angular accelerations.
