This article vividly tells the shape characteristics of the claws (hooves) of four animals, such as chicken, duckling, puppy and pony, so we can also compare the footprints of animals in the snow with other things that are common in life by means of metaphor and rhetoric.
Extended data:
None of the animals in the article hibernate.
Some animals, such as frogs, turtles and snakes, lie in caves when it is cold in winter and lack of food and water, and wait until the next spring to resume normal activities. Frogs are cold-blooded animals, and their own temperature will change with the change of external temperature.
The hibernating animals among warm-blooded animals are hedgehogs, squirrels, bobcats, bats and other small mammals. Compared with large animals, they have a large ratio of body surface area to volume, so they release a large proportion of heat, and they lack the productive food needed to maintain their body temperature in winter. So hibernation is an adaptation to these conditions.
