Defensive Adaptation
A body part or behavior that helps an animal protect itself from danger.
What is it?
A defensive adaptation is a trait that helps an animal avoid being eaten or harmed. Examples include sharp spines, camouflage, poison, or hiding. The Spur-winged Plover has spurs on its wings that it uses to fight off predators. Other animals, like porcupines with quills or skunks with smelly spray, also have defensive adaptations. The Sunbittern has a unique defensive adaptation: when threatened, it opens its wings to reveal eye-like patterns that startle predators. The Puff Adder has a defensive adaptation: it inflates its body with air and hisses loudly to scare away threats. This makes it look bigger and more dangerous. The Puff Adder also uses camouflage to hide from predators and prey. The Western Cottonmouth has a distinctive defensive adaptation: when threatened, it opens its mouth wide to show the white lining inside, which is why it is called a cottonmouth. This display warns predators to stay away. It may also vibrate its tail and release a musky smell. The tomato frog has a defensive adaptation: when threatened, it puffs up its body and turns bright red, resembling a tomato. If caught, it secretes a white substance from its skin that deters predators. The Henkel's leaf-tailed gecko uses camouflage as its main defensive adaptation, blending perfectly with tree bark and leaves to avoid detection.
Why it matters
Defensive adaptations help animals survive in the wild. They show the many creative ways animals have evolved to protect themselves.

防御适应
帮助动物保护自己免受危险的部位或行为。
这是什么?
防御适应是一种帮助动物避免被吃掉或受伤的特征。例子包括尖刺、伪装、毒液或躲藏。距翅鸻的翅膀上有距,用来击退捕食者。其他动物,如豪猪的刚毛或臭鼬的臭喷,也有防御适应。太阳鸬鹚有一种独特的防御适应:受到威胁时,它会展开翅膀露出像眼睛一样的图案来吓唬捕食者。膨蝰蛇有一种防御适应:它用空气膨胀身体并大声嘶嘶作响以吓跑威胁。这使它看起来更大、更危险。膨蝰蛇还使用伪装来躲避捕食者和猎物。西部棉口蛇有一种独特的防御适应:受到威胁时,它会张大嘴巴露出内部的白色衬里,因此得名棉口蛇。这种展示警告捕食者远离。它还可能振动尾巴并释放麝香味。番茄蛙有一种防御适应:受到威胁时,它会膨胀身体并变成亮红色,像番茄一样。如果被抓住,它会从皮肤分泌白色物质来阻止捕食者。亨克尔叶尾壁虎使用伪装作为其主要防御适应,与树皮和树叶完美融合以避免被发现。
为什么重要
