Metamorph external morphology

This file contains morphometric data for Agalychnis callidryas metamorphs on the day they emerged from the mesocosm in which they were reared as larvae. They were reared at either 5, 25, or 50 individuals per mesocosm. The file contains the date of emergence, the tank (mesocosm) number, rearing density, and metamorph ID for each individual. The measurements include snout-vent length, belly width and tail length, as well as body mass. The linear measurements were made when the metamorph was asleep in its water conservation posture on the side of a small, clear cup. We used dial calipers to make each measurement through the cup wall. Snout vent length was the distance from the tip of the snout on the most anterior end of the animal to the vent (cloaca). The belly was measured at its widest part, and the tail was measured from its base to its tip.

本文件收录红眼树蛙（Agalychnis callidryas）变态幼体从其作为幼虫饲养的中型实验生态系统（mesocosm）中钻出当日的形态测量数据。这些幼体的饲养密度分别为每中型实验生态系统5只、25只或50只个体。该文件包含每只个体的钻出日期、饲养缸（中型实验生态系统）编号、饲养密度以及变态个体编号。测量指标涵盖吻肛长、腹宽、尾长与体质量。所有线性测量均在变态幼体以保水姿态静伏于小型透明杯侧壁时完成，研究人员通过杯壁使用游标卡尺完成各项测量。其中，吻肛长为动物最前端吻部尖端至泄殖腔（vent）的距离；腹宽测量于腹部最宽处；尾长则从尾基部测量至尾尖。
