A family of limbless tropical amphibians including the caecilias, the largest family within the order Gymnophiona.
From caecilia + -idae (taxonomic family suffix). This follows Linnaean binomial classification convention for grouping related organisms.
The Caeciliidae family has over 200 species and they're incredibly underappreciated in popular science—most people don't even know they exist, but they've been evolving separately from frogs for over 300 million years.
