The air-filled tracheal respiratory system of insects prevents them from diving deeply in water. It is argued that this is the major factor in preventing insects from colonizing the open sea: they cannot descend sufficiently deeply in the daytime to escape being eaten by fish.
昆虫充满空气的气管呼吸系统使它们无法在水中深度潜水。有人认为，这是阻止昆虫在公海生存的主要因素：它们在白天无法下潜到足够深的地方以躲避被鱼类吃掉。
