ETHOLOGICAL SIGNIFICANCE OF BODY COLORATION AND PATTERN IN FISHES

黑色素浓缩激素(MCH)通过其在效应细胞膜上的特定受体作用于发色团。倒立是一种奇特的鱼，正如它的俗称所示，它通常是倒立游泳的。它的腹部皮肤含有黑素载体，像背部皮肤一样，受到交感神经和内分泌系统的控制。一些豆科鱼类，包括红嘴鱼和蓝绿色豆科鱼，表现出绿色的色调，是通过在黄色背景下出现蓝点来实现的。蓝色和黄色都是基于非理想型的多层薄膜干涉现象，发生在那里特殊的虹膜基团中。主要通过对视网膜内视觉细胞分布的组织学观察，检查侧眼的视力。据推测，如果物体之间的距离超过2厘米，鱼就会把另一个物体视为均匀的绿色实体。许多苦味树种在树干的侧部有绿色的垂直条纹。主要研究玫瑰的苦味，我们可以证明虹膜基团是其变色的主要原因。当从鱼的水平上看带子时，反射率较高的金色色调会减弱。如果凹陷角度或仰角增加，色调将从蓝转到蓝绿。这些现象是由于虹膜载体中反射血小板的特殊排列造成的。在学校里，这一物种的个体通过看到其他物种的乐队而有序地排列。也就是说，它们似乎通过识别附近游泳的其他人的鲜艳条纹来保持自己的位置。结论是，乐队对他们的在校行为有重要影响。

Melanin-concentrating hormone (MCH) was shown to act on chromatophores through its specific receptor on the membrane of the effector cells. Upside- down catfish is a curious fish, which usually swim upside-down, as its common name signifies. Its ventral skin contains melanophores, which are controlled, like those on dorsal skin, by both sympathetic nervous and endocrine systems. Greenish hue as displayed by some damselfishes, including scalycheek and blue- green damselfishes, is realized by the presence of blue spots against yellowish background. Both blue and yellow are based on multiple layered thin film interference phenomenon of the non-ideal type, occurring in the peculiar iridophores there. Mainly through histological observations on the distribution of visual cells in the retina, the visual acuity of the lateral eye was examined. It was deduced that the fish sees another one as homogeneously green entity, if the object is more than 2 cm apart. Many bitterling species possess green vertical stripes on the lateral part of the trunk. Working mainly on the rose bitterling, we could show that iridophores were primarily responsible for its coloration. When the band is viewed from the level of the fish, golden hue with higher reflectance damonates. If the angle of depression or elevation increases, the tone shifts to blue through blue-green. These phenomena are due to special arrangement of reflecting platelets in the iridophores. In schools, individuals of this species make orderly ranks by seeing others' band. That is, they seem to keep their positions by recognizing the bright-colored stripe of others swimming nearby. The conclusion was that the band is of great importance for their schooling behavior.
