Are the monkey's ears big or small, and the monkey's eyes big or small?

Small ears. Monkeys usually have bigger eyes, closer to the front of their faces and shorter mouths. Most monkeys' faces are flat, which enables them to look forward and see a lot of overlap in their eyes' field of vision, which can form stereoscopic vision. The original meaning of cleverness is to be alert. Macaques have big ears and bright eyes. In addition, compared with other animals, their IQ and learning ability are obviously stronger, and they are closer to humans, leaving a smart impression.
