Plaice(Pleuronectes Plessa)是一种比目鱼，以能够改变其身体模式而闻名，可能是为了伪装。这项研究调查了幼鱼使用的各种图案，描述了它们如何对三种人工背景之间的变化做出反应。有两种基本模式处于主动控制之下，即细小的“斑点”和较粗的“斑点”。这些图案叠加在一个相当均匀的地面上。对于所研究的六条辫子，斑点和斑点图案的表达水平随着视觉背景的不同而连续和独立地变化，并且以与它们的隐蔽性一致的方式变化。在热带比目鱼Botus ocellatus和两个温带物种Paralichthys lethostigma和Pseudopleuronectes americanus之间，鳕鱼似乎介于两者之间，后者有三个独立的基本模式，而两个温带物种各有一个。考虑混合少量的颜色图案是如何有效地进行伪装是很有趣的，为什么这项任务的需求可能会导致物种之间的差异。
Plaice ( Pleuronectes platessa) is a flatfish well-known for the ability to vary its body pattern, probably for camouflage. This study investigates the repertoire of patterns used by juvenile plaice, by describing how they respond to shifts between three artificial backgrounds. Two basic patterns are under active control, fine `spots' and coarser `blotches'. These patterns are superimposed on a fairly uniform ground. For the six plaice studied, the levels of expression of the spot and blotch patterns varied continuously and independently according to the visual background, and in a manner consistent with their being cryptic. The repertoire of plaice appears to be intermediate between the tropical flatfish Bothus ocellatus, which has three separate basic patterns, and two temperate species Paralichthys lethostigma and Pseudopleuronectes americanus, which have one each. It is interesting to consider how mixing a small number of coloration patterns is effective for camouflage, and why the demands of this task may lead to differences between species.
