由于欧洲青蛙（Rana spp.）已纳入德国濒危物种监管范围，非洲爪蟾（南非爪蛙）越来越多地用于动物研究和教育。由于对生长数据的统计分析很少，因此不一定能达到最佳的生长率和群体同质性。变态后，X. laevis 表现出一种尚未被了解的生长变异性。在这项研究中，确定了环境因素对这种变异性的影响。摄食、人口密度、背景颜色、水温、藏身之处、水位和水护理均被单独检查。记录体重和体长的发展。一方面，饲养计划、人口密度、覆盖范围和饮水护理与另一方面的增长之间存在明确的相关性。不太重要的是水温、水位和背景颜色。观察到的生长变异性也被认为具有行为学根源。
Since the European frogs (Rana spp.) have fallen under the German endangered species regulation, Xenopus laevis (South African Clawed Frog) is being used increasingly in animal research and education. Optimal growth rates and homogeneity of groups have not necessarily been attained as little statistical analysis of growth data has been available. Following metamorphosis, an as yet not understood variability of growth is exhibited by X. laevis. In this study the effect of environmental factors on this variability was determined. Feeding, population density, background colouring, water temperature, the availability of hiding places, water level and water care were each examined separately. Development of body weight and body length were recorded. A definite correlation between the feeding programme, population density, cover and water care on the one hand and growth on the other were seen. Of lesser importance were water temperature, water level and background colouring. The observed variability of growth is assumed to also be of ethological origin.
