在漫长的演化进程中,弱小的动物为了生存往往都有各自的规避、防身本领。保护色是最常见的一种。变色龙和章鱼也许是演化得最成功的两种变色动物,它们都能在很短的时间里变换体色以适应身处的环境。章鱼不仅善于变色,还能施放“烟幕弹”逃生,即能像乌贼一样喷射“墨汁”。不久前,澳大利亚和英国的三位专家在印度尼西亚热带海域里发现了一个新的品种,这种章鱼不仅能随环境随时改变体色,还能模仿多种可怕动物的形体来吓退掠食者的进攻。
In the long process of evolution, weaker animals often have their own avoidance and self-defense skills in order to survive. Protective color is the most common one. Chameleons and octopuses may be the two most color-changed creatures that have evolved, and they all change color in a short amount of time to suit the environment. Octopus not only good at discoloration, but also cast “smoke bombs ” to escape, that is, the same as squid spray “ink ”. Not long ago, three experts from Australia and the United Kingdom found a new breed in the tropical Indonesian sea. This octopus can not only change the color of the body as the environment changes, but also mimic many horrible animal forms to deter predators attack.
