Responses to water-borne chemicals by the octopus Eledone cirrhosa (Lamarck, 1798)

Description
Summary:The octopus Eledone cirrhosa (Lamarck, 1798), enclosed in a small chamber of flowing sea water, was tested for responses to water-borne chemicals. Incidence of body movements and change in ventilation rate were recorded by a non-invasive technique. At concentrations no more than 1 × 10 −4 M at the animal, the octopuses responded to betaine, glycine, proline, alanine, lactic acid, and serine (order of decreasing sensitivity). Glutamic acid and trimethylamine oxide were considerably less stimulatory, arginine and taurine were hardly more effective than sea-water controls.
