There are several ways to classify animals

There are many different ways to classify animals, but the most commonly used is the binomial nomenclature created by biologist Carolus Linnaeus in the 18th century, which is based on the morphology and characteristics of animals. In addition, there are several common classification methods:

1. Cell structure: Classification based on the structure of animal cells, such as prokaryotes and eukaryotes.

2. Nutritional mode: Classification based on the nutritional mode of animals, including carnivores, herbivores, omnivores, etc.

3. Living habits: Classification based on the living habits of animals, such as aquatic animals, terrestrial animals, aerial animals, etc.

4. Genetic relationship: Classification based on the genetic relationship of animals, including molecular systematics, evolutionary systematics, etc.

5. Universal classification: Classification based on morphology, anatomy, embryonic development and other characteristics, such as the invertebrates and vertebrates in the modern animal kingdom.

In short, animal classification is an important means of classifying and studying animals, which can help people understand the characteristics of animals and their evolutionary process more deeply.
