The structure of the papillomatous junction between epidermis and dermis (papillomatous netting, PN) in the skin of cetaceans (white whales, bowhead, and gray whales) and sirens (American manatee, dugong) was studied and compared using histophysiological and morphogeometric methods. The relative extent of PN development proved to be similar in members of both orders, but significant differences were found in PN configuration, the volume of "free area of grille", the degree of skin vertical compression, and skin density, which influence buoyancy. The differences are discussed from the viewpoint of species biology.
利用组织生理学和形态几何学方法，对鲸类动物（白鲸、弓头鲸和灰鲸）及海牛目动物（美洲海牛、儒艮）皮肤中表皮与真皮之间乳头状连接结构（乳头状网，PN）进行了研究和比较。结果表明，两个目成员的PN发育相对程度相似，但在PN形态、“格栅自由区域”体积、皮肤垂直压缩程度和影响浮力的皮肤密度方面存在显著差异。从物种生物学角度对这些差异进行了讨论。
