Definition

Noun: * A taxonomic family of amphibians within the order Anura, commonly known as disc-tongued frogs. This family is characterized by having a distinctive, round, disc-like tongue that is largely attached to the floor of the mouth and cannot be extended freely. Members of this family are primarily found in the Old World (Europe, North Africa, and parts of Asia).

Usage Notes

• Family Discoglossidae is a scientific term used in zoology, herpetology, and biological taxonomy. It is not used in everyday conversation.

• In modern taxonomic revisions, some of the genera traditionally placed in Discoglossidae have been moved to other families (such as Alytidae). However, the term Discoglossidae remains valid and in use for a specific clade.
