Definition
Proper noun (used with singular or plural verb): * A family of lizards native to the Americas, commonly known as iguanas and their relatives. This family is characterized by pleurodont teeth (attached to the inner side of the jaw), often herbivorous or omnivorous diets, and frequently includes species with dorsal crests, dewlaps, and spines.
Usage Notes
- Capitalization: "Iguanidae" is always capitalized as it is a proper noun denoting a taxonomic family name.
- Verb Agreement: It can be used with a singular verb when referring to the family as a single taxonomic unit (e.g., "Iguanidae is a large family") or with a plural verb when referring to the members of the family collectively (e.g., "Iguanidae are found from North America to Polynesia").
- Context: This term is primarily used in scientific, zoological, and herpetological contexts.
Examples
- The green iguana is one of the most recognizable members of the Iguanidae.
- Iguanidae includes a diverse range of species, from desert-dwelling chuckwallas to marine iguanas.
- Taxonomic revisions have moved some genera, like , out of the family Iguanidae.
Advanced Usage
- Phylogenetic Context: In modern cladistics, the traditional, broad family Iguanidae is sometimes split into multiple smaller families (e.g., Iguanidae, Corytophanidae, Dactyloidae), a group collectively referred to as iguanians or the Iguania infraorder. In this stricter sense, Iguanidae may refer only to "true" iguanas.
- Example: "The monophyly of the core Iguanidae is well-supported by molecular data."
