The behavior of the ragged sea hare, Bursatella leachii pleii Rang, was observed in its natural habitat and in captivity. An indication of the seasonal availability of Bursatella in Puerto Rico was obtained by making multiple observations at a single site. The behavior patterns of Bursatella in the field were indicative of a daily rhythm. They tended to be found in groups at sunrise and as isolated individuals in the afternoon. They were observed to assemble following sunset and to disperse in the morning. Certain aspects of this rhythmic pattern of behavior persisted in animals held in the laboratory, where copulation was the most common behavior in the morning and feeding-related activities became more prevalent in the afternoon. Specific behaviors related to autonomic function (respiration and digestion) were also observed and quantified. It is proposed that the rich behavioral repertoire exhibited by B. leachii, and the ease with which these animals are observed in their native habitat, provide favorable systems for studying neuronal mechanisms involved in the organization and evolution of complex behavior.
在自然栖息地和圈养环境中观察了糙海兔（Bursatella leachii pleii Rang）的行为。通过在单一地点进行多次观察，获得了波多黎各糙海兔季节性可获得性的指标。糙海兔在野外的行为模式表明存在日节律。它们往往在日出时成群出现，下午则为单独个体。观察到它们在日落后聚集，早晨分散。这种节律性行为模式的某些方面在实验室饲养的动物中持续存在，在实验室中，交配是早晨最常见的行为，与进食相关的活动在下午变得更为普遍。还观察并量化了与自主功能（呼吸和消化）相关的特定行为。有人提出，糙海兔表现出的丰富行为库，以及在其原生栖息地观察这些动物的便利性，为研究参与复杂行为组织和进化的神经元机制提供了有利的系统。
