摘要: Abstract 1. The effects of anaesthesia induced by immersion in urethane (3%), ethanol (2%) or seawater at 4°C were compared Octopus vulgaris. 2. Immersion appeared to traumatise the animals; majority began climb out within 30 seconds immersion. This was not observed with cold water. All three substances “anaesthesia” 2–5 min. 3. water produced a typical flashing chromatophore display seen either other procedures. 4. A period hyperventilation during recovery from all anaesthetics. Recovery respiration, activity and posture always occurred that sequence irrespective anaesthetic. 5. criteria for assessing general vulgaris are discussed.
