Three Anthozoan Neuropeptides, Antho-RFamide and Antho-RWamides I and II, Modulate Spontaneous Tentacle Contractions in Sea Anemones

Abstract
Behavioural coordination in sea anemones involves both excitation and inhibition. Examples include reciprocal inhibition between longitudinal and circular muscles (Batham and Pantin, 1954), inhibitory actions during peristalsis (Ewer, 1960; McFarlane, 1974a), joint excitatory and inhibitory innervation of sphincter muscle (Lawn, 1976) and inhibition of neural pacemakers (McFarlane, 1974b).
