6. The professor explains the concept of protective resemblance by giving two examples.
First, he describes that some animals temporarily change their appearances to avoid detection from predators. The flounder is a good example of this. It alters its color to match with the background, which is good for hiding the body. To be specific, it has special skin cells that release diverse pigments to individual cells (This point is unclear) to blend into the ocean floor. Also its transformation speed is very fast. (It seems this sentence is not essential)
Second, he describes that some animals have permanent patterns on their body to make them look like another things. The gecko is a good example. Its tail is like the leaf and its body is similar to tree's twig. The overall shape of this animal is difficult to detect easily. As a result, when predators look for preys, they are likely to neglect this animal.
