本研究的目的是开发一套实用的变性阶段的虎蝾螈，将（1）提供一个早期的和可量化的标志开始变态和（2）不依赖于知识的最大值鳃长或尾高。从虎钝口鱼幼虫获得20个形态学参数，因为它们通过实验室诱导的变态（21°C，连续光）进行。这些参数包括体重、鳃长和尾高。启动或变态的持续时间不能预测时，参数表示相对于幼虫在实验室条件下举行的天数。
The aim of this study was to develop a set of practical metamorphic stages for the tiger salamander Ambystoma tigrinum that would (1) provide an early and quantifiable marker of the onset of metamorphosis and (2) not be dependent on knowledge of maximal values of gill length or tail height. Twenty morphological parameters were obtained from Ambystoma tigrinum larvae as they progressed through laboratory‐induced metamorphosis (21°C, continuous light). These parameters included measures of body weight, gill length, and tail height. Initiation or duration of metamorphosis could not be predicted when parameters were expressed relative to the number of days larvae were held in laboratory conditions.
