Small animals that are not afraid of rain in rainy days include ducks, otters, walruses, fish and frogs. 1. Ducks: Ducks are covered with grease. Ducks will coat their feathers with grease when tidying their feathers, so that rain can't penetrate into them, so they are not afraid of getting wet. 2, otter: otter fur is delicate, warm and waterproof under water, and the rain density on land is not as high as that in water, so it is not afraid of rain.
