This study tests for interspecific evidence of Heincke's law among hagfishes and advances the field of research on body size and depth of occurrence in fishes by including a phylogenetic correction and by examining depth in four ways: maximum depth, minimum depth, mean depth of recorded specimens and the average of maximum and minimum depths of occurrence. Results yield no evidence for Heincke's law in hagfishes, no phylogenetic signal for the depth at which species occur, but moderate to weak phylogenetic signal for body size, suggesting that phylogeny may play a role in determining body size in this group.
本研究检验了盲鳗中Heincke法则的种间证据，并通过纳入系统发育校正以及从四种方式考察深度：最大深度、最小深度、记录标本的平均深度以及出现的最大深度与最小深度的平均值，推进了鱼类体型与出现深度的研究领域。结果未发现盲鳗中存在Heincke法则的证据，物种出现深度不存在系统发育信号，但体型存在中度至微弱的系统发育信号，这表明系统发育可能在决定该类群的体型方面发挥作用。
