Because of its long existence in this bait, the duck’s body has evolved many points to adapt, such as having a lot of body fat around the internal organs, floating a pair of well-developed fat glands, covered with a coating on the outside of the body. a thick layer of feathers, difficult to absorb water.

When coming out of the water, the duck turns its head towards the tail and pokes at the fat gland in the center of the float, and then on the feathers, all over the body, combing the wet fluff, shaking off the water on the feathers, and then applying it on it. a layer of grease, which makes the feathers impermeable to water.

In winter, the air temperature outside the room is generally slightly lower than the temperature of the lake water, moreover, ducks are active in swimming continuously, so their body temperature increases, which also has anti-cold effects.

The duck mainly lives in the water, between the three front toes of the duck’s feet there is a skin membrane connected, its chest is very large and well-proportioned. To be able to swim quickly, in addition to the big feet in contact with the wide water to increase the forward thrust, the position of the legs is also slightly pushed back. So after the duck comes ashore, its legs are not in the middle of the body but slightly leaning back, then if the duck’s body is balanced, it is likely that the duck will fall forward, so the duck must lean back, causing the weight of the body to rest on the duck’s legs. To maintain the balance of the body and also because the duck’s legs are a bit short, the duck waddles and waddles.
