COMPLEX AND MODIFIABLE BEHAVIOR PATTERNS IN CALLIACTIS AND STOMPHIA

Three behavior patterns in sea anemones are analyzed in relation to the receptors, elfectors, and co-ordinating s)stems required for their perfomance: Calliactis responding to molluscan “shell-factor.” Stomphia swimming to starfish and to electrical stimulation. Stomphia transferring to shells of it...

Description
Summary:Three behavior patterns in sea anemones are analyzed in relation to the receptors, elfectors, and co-ordinating s)stems required for their perfomance: Calliactis responding to molluscan “shell-factor.” Stomphia swimming to starfish and to electrical stimulation. Stomphia transferring to shells of its commensal Modiolus modiolus . These complex purposive acts are triggered and controlled by the excitation of chemoreceptors. Co-ordinating nervous components have not been identified. These specific responses offer possibilities for tests on learning for which unequivocal evidence does not exist in coelenterates.
