Abstract

H.G. Moser was not particularly well known regarding the Elopomorpha, but he began his seminal 1981 fish larvae morphology review by describing the mysteries of European eels and their leptocephali, and he eventually described some California Current leptocephali. Descriptions of all types of leptocephali and then microscope photographs have revealed complex pigmentation patterns and diverse body shapes that parallel the features of the other teleost fish larvae that his review showed so clearly, some of which appear to mimic gelatinous zooplankton (GZ). Most recently, underwater photographs and video of leptocephali indicate that predator avoidance through transparency, shape-change-mediated mimicry, or morphological features have evolved in response to natural selection from predation in ways generally similar to other fish larvae. Several families of leptocephali perform remarkable curling into round or flattened shapes or use expandable chromatophores when threatened, which appears to mimic GZ for predation reduction. Like a number of other teleost fish larvae, some leptocephali have body extensions or telescopic eyes, and at least one has a long caudal filament with pigmented swellings that is similar to the remarkable GZ mimicry appendages of some fish larvae. The morphology and use of mimicry of leptocephali in comparison to other fish larvae is reviewed as a tribute to H.G. Moser’s remarkable career.

在H.G. Moser开创性的“海洋鱼类幼虫的形态和功能方面”发表43年后:细头鱼和其他海洋硬骨鱼幼虫的共性
h·g·莫泽在Elopomorpha方面并不是特别出名,但他在1981年通过描述欧洲鳗鱼和它们的细头体的奥秘开始了他开创性的鱼类幼虫形态学回顾,他最终描述了一些加利福尼亚流的细头体。对所有类型的细头鱼的描述和显微镜照片揭示了复杂的色素沉着模式和多样的身体形状,这些特征与他的综述中清楚显示的其他硬骨鱼幼虫相似,其中一些似乎模仿凝胶状浮游动物(GZ)。最近,细头鱼的水下照片和视频表明,它们通过透明、形状变化调节的模仿或形态特征来躲避捕食者,这是对自然选择的反应,其方式与其他鱼类幼虫大致相似。钩头鲸的几个科在受到威胁时表现出非凡的卷曲成圆形或扁平形状或使用可膨胀的色素体,这似乎模仿GZ来减少捕食。像许多其他硬骨鱼的幼虫一样,一些钩头鱼有身体延伸或伸缩的眼睛,至少有一条长尾丝有色素肿胀,类似于一些鱼类幼虫的显著的GZ模仿附属物。本文将细头鱼的形态和拟态与其他鱼类幼虫的比较作一综述,作为对H.G.莫泽非凡事业的致敬。
