答案 Disguise Many species of animal practise tactics to disguise their appearance, / usually by blending in with their environment. / Such tactics mainly depend on the physical characteristics or behavior of a species and its enemies. / Usually environmental and behavioral factors can cause species to employ a variety of tactics. / And the most common one is background matching, / in which a species conceals itself by resembling its environment. / In its simplest form, animals such as deer and squirrels / resemble the earth tones of their environment. / Another important tactic is to have disruptive color and pattern. / This form of disruption causes attackers to misidentify what they are looking at. / Many butterflies have large patterns on their wings, / which may misdirect attackers from the soft, vulnerable part of their body. / Actually disguise can be practised by both prey and their enemies. / So it may help prey to avoid their enemies / while the latter may also sneak up on their prey with this tactic. /

解析     伪装
   许多种动物会采取伪装策略。这些策略主要取决于某一种动物和其天敌各自的体型特征以及生活习性。其中最常见的一种是背景匹配策略,运用这种策略的动物会通过拟态为它周围的环境来隐藏自己。另一个重要的策略是拥有扰乱性的颜色和花纹。这种方式可以让攻击者错误辨别眼前之物。
