Definition
- Noun:
- (Biology) A taxonomic rank: A "suborder" is a formal category in biological classification that ranks below an order and above an infraorder or family. It represents a major subdivision within an order, grouping together related families.
Usage
- The term "suborder" is used almost exclusively in scientific contexts, particularly in biology (zoology, botany) and paleontology, to describe a level in the hierarchical system of taxonomy (domain, kingdom, phylum, class, order, suborder, family, genus, species).
- It is a countable noun. The standard plural form is "suborders."
Examples
- In the order Carnivora, the suborder Feliformia includes cats, hyenas, and mongooses.
- The botanist identified a new plant family and proposed placing it within an existing suborder.
- The order Primates is divided into two main suborders: Strepsirrhini (lemurs and lorises) and Haplorhini (tarsiers, monkeys, apes, and humans).
Advanced Usage
- "To be placed in a suborder": This phrase describes the taxonomic action of classifying a group within a specific suborder.
- The newly discovered fossil species was placed in the suborder Theropoda.
- The concept can be extended metaphorically in very formal or technical writing outside of biology to mean "a secondary or subordinate order or category," though this is rare.
Variants and Related Words
- Subordinal (adjective): Pertaining to a suborder.
- The subordinal classification was debated by the taxonomists.
- Infraorder (noun): A taxonomic rank below a suborder and above a family.
- Superorder (noun): A taxonomic rank above an order and below a class.
Synonyms
- Taxonomic subdivision: A general term for any rank below an order.
- Division (in a general hierarchical sense, not the botanical rank "Division" which is equivalent to Phylum).
Notes
- There are no specific idioms or phrasal verbs associated with the term "suborder" due to its highly specialized scientific nature.
- When writing, the term is often italicized in scientific texts (e.g., Haplorhini) following conventions for taxonomic ranks below the genus level.
Noun
