What other animals do you know about winter? Write two kinds.

1. Snakes hibernate collectively. They snuggle up to each other, hibernate together, and wake up in spring to warm up. If you spend the winter alone, you will freeze to death. Like the frog, it is also a warm animal, and gathering together can reduce the mortality rate.

Bears hibernate because it is not easy to find food in winter. In autumn, they eat a lot and make themselves fat. In winter, they rely on fat for nutrition. However, they wake up when they hibernate. ?

Rabbits have thick hair to keep warm, so they are not afraid of cold in winter. But if the fur is wet, rabbits can easily catch cold. Therefore, the owner should pay special attention not to bathe rabbits in winter.

4. Bats also hibernate. It hung upside down in the air with the sharp claws of its hind feet in the cave for half a year.

Extended data:

Different species of invertebrates have different life cycles. Most invertebrates are egg-laying animals, and some need to go through various larval forms, such as butterflies, moths and other insects; Others become adults as soon as they hatch.

Animals can't synthesize organic matter from inorganic matter, but can only treat organic matter as food, which can be eaten and relied on. They are composed of cells with nucleus, no cell wall, movement and substrate.

Therefore, animals have different morphological structures and physiological functions from plants from feeding, digestion, absorption, breathing, circulation, excretion, feeling, exercise to reproductive life activities.

Due to the variety of animals, human beings still lack in-depth research and understanding of some groups, so until now there is no perfect animal classification system in the world.

The difference is because some scholars upgraded some different classes to phylum, such as rotifer, abdominal hair, moving kiss, linear, nematode and other animals in the original prosthesis cavity, and some scholars upgraded them to phylum.
