The biological family that includes all worm-lizards and amphisbaenas, a group of legless reptiles.
From 'Amphisbaena' + the Latin family suffix '-idae', following scientific nomenclature established in the 1800s.
Amphisbaenidae was one of the first reptile families that scientists realized didn't fit into simple categories like 'snakes' or 'lizards'—they're so specialized that they needed their own entire family.
