Revealing Coloration
Many animals use coloration to protect themselves from predators. One defensive strategy involving the use of coloration is what is known as revealing coloration. Animals employing this strategy have an area of bright color on some part of their body; this bright color is usually hidden from predators’ view. When approached by a predator, the animal suddenly reveals the area of bright color; this unexpected display of color startles or confuses the predator and provides the would-be prey with an opportunity to escape.

There’s a large tropic insect called the peanut bug. Yes, like the peanuts that you eat. Uh, and the peanut bug’s front wings are colored so that they blend in with their surroundings. But its back wings, which are usually closed and hidden, have these bright colorful spots on them. And when the peanut bug’s attacked, it suddenly opens its back wings and out pop these big bright colors. And that surprises the predator and gives the peanut bug a chance to get away.
And then you have a butterfly called the Morpho butterfly. And parts of the wings of Morpho butterfly are very shiny. They reflect a lot of sunlight. When this butterfly is resting, this shiny part of its wings is hidden. Now, Morpho butterfly is often attacked by birds. So when a bird approaches, the Morpho flies away when the Morpho flaps its wings. All the bird can see is a flash of light reflected from the Morpho’s wings. Those flashes of light make it difficult for the bird to follow the Morpho and the Morpho is usually able to get away.

리스닝 요약
The first example is a large tropic insect called the peanut bug. (첫번째 예는 큰 열대 곤충인 땅콩 벌레임)
Its front wings are colored. (그것은 색상이 있는 앞 날개를 가지고 있음)
They blend in with their surroundings. (그 날개들은 주변 환경과 잘 섞임)
But their back wings have bright colorful spots that are usually closed and hidden. (그러나 밝은 색상의 점들을 가진 뒷 날개는 보통 닫혀있고 숨겨져 있음)
When the peanut bug is attacked, it suddenly opens back wings and displays these big bright colors. (땅콩 벨레가 공격을 받았을 때, 그것은 갑자기 뒷 날개를 열고 크고 밝은 색을 드러냄)
This display surprises the predator and the peanut bugs can have a chance to escape. (그래서 포식자를 놀라게 하고 땅콩 벌레는 도망갈 기회를 얻을 수 있음)
The second example given is the Morpho butterfly. (두번째 예는 Morpho 나비임)
Parts of the wings of Morpho butterfly are very shiny and reflect sunlight. (Morpho 나비의 날개 부분은 매우 반들거려서 햇빛을 반사함)
This shiny part of its wings is hidden but when a predator approaches, the Morpho flaps its wings so that sunlight is reflected from the wings. (이 밝은 부분은 숨겨져 있지만 포식자가 접근할 때, Morpho 나비는 그 날개를 퍼덕거려서 햇빛이 반사되도록 함)
Due to the reflection, it is hard for a predator to see the butterfly and this is the Morpho butterfly’s strategy to escape from an attack. (반사 때문에 포식자는 나비를 보기 힘들고 나비는 공격으로부터 벗어날 수 있음)



(샘플 답안)
The reading passage introduces the concept of revealing coloration, wherein animals possess bright areas of color on their bodies.
In the lecture, the professor offers examples to illustrate this phenomenon. The first example pertains to the peanut bug, a large tropical insect. The front wings of the peanut bug blend seamlessly with its surroundings, while its back wings feature brightly colored spots that are typically concealed. However, when the peanut bug is threatened, it suddenly reveals these colorful spots by opening its back wings. This sudden display startles predators, providing the peanut bug with an opportunity to escape unscathed.
The professor’s second example involves the Morpho butterfly. Certain parts of the Morpho butterfly’s wings are highly reflective and shine brightly in sunlight. These reflective areas are normally hidden, but when a predator approaches, the Morpho flaps its wings, causing sunlight to bounce off its wings. This reflection of sunlight makes it challenging for predators to spot the butterfly, serving as a strategy for the Morpho to evade potential attacks.
