Infraphylum意思
"Infraphylum" is a term used in taxonomy, the scientific classification of organisms, to denote a group or rank that is below the level of phylum (or division in the classification of plants) and above the class level. It is a subdivision of a phylum and is used more commonly in the classification of invertebrates, especially insects.
The term "infraphylum" is not as widely used in the classification of vertebrates, where different hierarchical terms are employed. For example, in vertebrate classification, the ranks below the phylum level include classes, orders, families, genera, and species.
Here's a simplified taxonomic hierarchy from the most general to the most specific:
- Domain
- Kingdom
- Phylum (or Division)
- Class
- Order
- Family
- Genus
- Species
The infraphylum is a subdivison within the phylum level, helping to further categorize and organize the vast diversity of life on Earth.
