补充资料：大洋带生物
又称远洋带生物。指生活在沿岸带范围以外全部开阔大洋上层水区的生物。大洋带通常以阳光透入的最大深度（一般为200米）为下界，海水透明，光照充足，海水混合较均匀，盐度高，所含陆源性碎屑少，营养盐含量低，各种理化条件稳定。动植物种类和数量较沿岸带贫乏，生物量为0.01～5克/米2。主要有各种单细胞藻类，原生动物的有孔虫和放射虫，以及水母类、桡足类、若干头足类软体动物、各种中上层鱼类（鲨鱼、鲭、鲐、箭鱼、金枪鱼、鲑等）、爬行类的海蛇和海龟及哺乳动物的鲸类和海豹等。大洋带虽占世界海洋总面积的90％，但其生产率较低，平均初级生产力为50克碳/米2·年，鱼类生产力0.005克/米2·年，仅占世界海洋渔获量的4％。
