人们一直认为,变色龙变色的主要原因是它们能够通过采用环境的颜色来伪装自己,以避免潜伏在环境中的任何危险。

但实际上,这只是变色龙产生这种奇特颜色变化的众多原因之一,主要是由于心理或环境因素造成的。

这意味着这些爬行动物的精神状态在很大程度上影响着它们皮肤颜色的变化,每种颜色都意味着不同的事情:它们是否紧张、不安、害怕、警觉、放松等等。

此外,气候对变色龙的颜色变化也有很大影响,变色龙会根据环境温度进行自我调节。

变色龙为什么会变色?

如上文所述,这些动物变色主要有两个原因:温度反应和情绪变化。 请看下面的原因。

温度响应

首先需要注意的是,变色龙是一种外温动物。 这意味着它们不能自己产生体内热量。 因此,所有外温生物都依赖外部热源来达到一定的体温。

重要的是要知道,外温动物的许多性状会随着个体体温的变化而发生很大变化。 这些性状包括消化速度、奔跑或游泳的灵活性以及颜色等等。

因此,我们应该记住,深色吸收光和热,而浅色反射光和热。 事实上,变色龙利用它们的肤色作为恒温器来控制它们从环境中获得的温度。

情绪变化

变色龙也会根据自己的情绪改变颜色。 通常,变色龙在害怕时颜色会变深,而在兴奋时颜色会变浅。

此外,雄性和雌性之间也有区别:雄性比雌性更频繁地改变颜色,而雌性则倾向于使用更微妙的信号进行交流。

从这个意义上讲,雄性变色龙的颜色变化可以帮助它们吸引配偶。 当展示出鲜艳的颜色时,它会向雌性变色龙发出健康状态的信号。

因此,变色龙每天可能会根据不同的场合在几种不同的颜色之间切换。

变色龙如何变色?

对五只成年雄豹变色龙、四只成年雌豹变色龙和四只幼豹变色龙的研究表明,这些动物有两层厚厚的重叠的 "虹彩细胞",这种虹彩细胞具有色素并能反射光线。

根据这项研究,虹彩细胞中含有不同大小、形状和组织的 "纳米晶体",它们是变色龙颜色剧变的关键。

研究解释说,当变色龙的皮肤放松时,虹膜细胞中的纳米晶体靠得很近,因此这些细胞能专门反射短波,如蓝色波。

另一方面,当皮肤被激发时,纳米晶体之间的距离增加,虹膜(包含这些纳米晶体)选择性地反射较长波长,如黄色、橙色或红色。

毫无疑问,这些发现将有助于工程师和科学家在新技术中复制变色龙的变色能力,如消除眩光的设备等。
