一个由澳大利亚格里菲斯大学和迪金大学研究人员领导的团队发现，在中美洲伯利兹海域生活的一种珊瑚礁鱼能驯养浮游糠虾为其食物海藻施肥。相关发现或为进一步揭示野生动物最初如何被人类驯化提供线索。驯养其他物种是一种复杂行为，长期以来被认为是人类特有的行为，自然界中很难观察到人类以外的物种驯养动物的例子。
澳大利亚海洋学研究所科研人员确认，一条生活在西澳大利亚州海岸附近的81岁斑点笛鲷是世界上已知最长寿的热带珊瑚礁鱼。相关论文发表于新一期德国《珊瑚礁》杂志上。澳大利亚海洋学研究所在一份报告中说，该机构研究人员在西澳大利亚州海岸附近4个地点和印度洋中部的查戈斯群岛附近抽样调查了热带鱼的生长情况，共发现11条年龄超过60岁的鱼。在西澳大利亚州西北部一处名为罗利沙洲的珊瑚礁海域，研究人员发现了这条年龄高达...
