Definition

Noun: * A type of small, often brightly colored fish: A live-bearer is a fish that gives birth to free-swimming young, rather than laying eggs. These surface-feeding fish are typically found in fresh or slightly salty (brackish) warm waters and are sometimes used to help control mosquito populations.

Usage

The word "live-bearer" is used to classify and describe a specific biological group of fish based on their reproductive method. * It is a technical term common in biology, ecology, and the aquarium hobby. * It functions as a countable noun (e.g., a live-bearer, many live-bearers).
