Definition

Noun: 1. A large taxonomic order of gastropod mollusks: Pulmonata is a scientific name for a major group of snails and slugs that typically breathe air using a lung-like sac, instead of gills. This group primarily includes most land snails and slugs, as well as many freshwater species.

Usage Examples

• Noun:
  • The garden snail, a common sight after rain, belongs to the order Pulmonata.
  • Biologists study Pulmonata to understand the adaptation of mollusks to terrestrial life.
  • Unlike marine snails, members of the Pulmonata have evolved a vascularized mantle cavity that functions as a lung.

Advanced Usage

• As a taxonomic rank: The term is used formally in biological classification. It is often written in italics () to indicate it is a scientific Latin name.
  • The classification of Pulmonata within gastropods has been revised with modern genetic studies.
