一谈起伪装,人们往往会想到变色龙,因为它能快速地改变皮肤颜色,融入到周围环境中。实际上,自然界中比变色龙更善于伪装的动物还有很多,科学家将这一现象称为拟态,即指一种生物对另一种生物的模仿,包括行为、体态、外形甚至气味、外激素等方面的模仿,其主要目的,是为了被动地躲避天敌和主动地捕食等。乍一看,人们十有八九会认为这是一条蛇。其实它根本不是蛇,而是伪装成蛇的毛毛虫。为了模仿得更逼真,这种无害的毛毛虫有时甚至会对威胁它的捕食者做出蛇的攻击猛咬动作,让对方避之唯恐不及。 Speaking of camouflage, people often think of chameleons, because it can quickly change the color of the skin, integrated into the surrounding environment. In fact, there are many more animals camouflaged in nature than chameleons. Scientists refer to this phenomenon as mimicry, which refers to the imitation of one species by another organism, including behavior, posture, shape and even smell, pheromones, etc. Imitation, its main purpose is to passively evade predators and predators and so on. At first glance, people think it is a snake in the first time. In fact, it is not a snake, but a caterpillar disguised as a snake. In order to imitate more lifelike, this harmless caterpillar sometimes even bitten a snake’s attack on the predator who threatened it, letting the other side avoid it.
