Definition

Proper noun * A taxonomic family of reptiles: Family Chamaeleontidae is the scientific name for the group of lizards commonly known as Old World chameleons. This family is characterized by species known for their ability to change color, zygodactylous feet (toes fused into opposable bundles), independently mobile eyes, and long, projectile tongues for catching prey.

Usage

• Zoological Discussion: "Researchers are studying the evolutionary history of family Chamaeleontidae."
• Comparative Context: "Unlike iguanas, members of family Chamaeleontidae have prehensile tails."

Advanced Usage

• In some older or alternative taxonomic classifications, this group may be referred to as family Chamaeleonidae (a variant spelling) or be considered a superfamily.
