新生期有尾两栖类动物具有突出的外鳃，通过它们的外皮吸收大量的水和钠。鳃的结扎没有改变的吸收无论是水或钠在Necturus maculosus或Ambystoma tigrinum。在无尾目蝌蚪和鱼类中，鳃是这种交换的主要场所。这种限制鳃渗透性水生有尾目动物的可能的生理意义进行了讨论，以及这些特殊性质的基础。
Neotenic urodele amphibians that possess prominent external gills absorb substantial amounts of water and sodium across their integument. Ligation of the gills did not change the uptake of either water or sodium in Necturus maculosus or Ambystoma tigrinum. In anuran tadpoles and fish the gills are known to be a major site of such exchanges. The possible physiological significance of such a restricted branchial permeability in aquatic urodeles is discussed as well as the bases for these special properties.
