Which term refers to jawless fish?

Explanation:
Jawless fishes are classified as Agnatha, a name that literally means “without jaws” (from Greek a- “without” and gnathos “jaw”). These primitive vertebrates lack true jaws, and they include living examples like lampreys and hagfish. This set apart from Osteichthyes, which are bony fishes with ossified skeletons, and Chondrichthyes, which are cartilaginous fishes with skeletons made of cartilage. Acanthopterygii is a large subgroup within bony fishes known for their spiny fins. So the term that refers to jawless fish is Agnatha.
