The middle-ear structures from 5 Atlantic Loggerhead (Caretta caretta) and 1 Atlantic Ridley (Lepidochelys kempi) marine turtles from dead specimens found stranded in the lower Chesapeake Bay were dissected and examined superficially and by light microscopy. The marine turtle middle ear is poorly adapted as an aerial receptor in mammalian and reptilian terms. However, it appears well designed as a peripheral component of a bone conduction system. The thick tympanum, while disadvantageous as an aerial receptor, likely enhances low-frequency bone conduction hearing. The columella directly couples the cochlea and saccule so that its movement would stimulate each end organ. Turtle hearing is probably an integration of both outputs.
对从切萨皮克湾下游搁浅死亡的5只大西洋蠵龟（蠵龟属）和1只大西洋丽龟（丽龟属）的中耳结构进行了解剖，并进行了表面观察和光学显微镜检查。从哺乳动物和爬行动物的角度来看，海龟的中耳作为空气感受器适应性较差。然而，它似乎是作为骨传导系统的外周部件而设计良好的。厚厚的鼓膜虽然作为空气感受器有劣势，但可能增强了低频骨传导听力。镫骨直接连接耳蜗和球囊，因此其运动将刺激每个终器。海龟的听力可能是这两种输出的整合。
