颜色和体型是鱼类谱系之间存在差异的许多形态特征之一。其他动物群体中存在复杂的颜色和体型共变，但这两种形态特征之间的关系尚未在鱼类中得到严格检验。我们正式测试了蛇鲈（鲈科：Etheostomatinae）的颜色和体型之间的相关性，蛇鲈是一组北美淡水鱼，其雄性颜色和最大体型的存在情况各不相同。尽管未经校正的分析表明镖鲈的颜色特征和体型之间存在显着相关性，但经过系统发育校正的逻辑回归模型和方差分析却没有显示出显着的相关性，这表明体型不会成为复杂颜色的限制，反之亦然。这些结果在生态和行为背景下进行了讨论。
Coloration and body size are among the many morphological traits that vary among fish lineages. Elaborate coloration and body size covary in other animal groups, but relationships between these two morphological characteristics have not been rigorously examined in fishes. We formally test for correlations between coloration and body size in darters (Percidae: Etheostomatinae), a group of North American freshwater fishes that vary in the presence of male coloration and maximum body size. Although uncorrected analyses indicate a significant correlation between colour traits and body size in darters, phylogenetically corrected logistic regression models and ANOVAs revealed no significant correlations, suggesting body size does not act as a constraint on elaborate coloration or vice versa. These results are discussed in an ecological and behavioural context.
