BEHAVIOR IN HYDRA PIRARDI: INHIBITION OF THE CONTRACTION RESPONSES OF HYDRA PIRARDI.
Hydra pirardi contracts spontaneously and in response to external stimuli of light and mechanical agitation. Inhibition of these contractions occurs when the animal feeds on Artemia salina or when reduced glutathione is present in the environment. Such inhibition demonstrates the control of one receptor-effector system by another in hydra.
