The plural form of caecilia; multiple individuals of limbless tropical amphibians, or the taxonomic class name.
From Latin caecilia + -ae (plural feminine ending). The plural preserves the Latin grammatical form used in scientific nomenclature.
When biologists talk about multiple caecilias or the group as a whole, they use caeciliae—it's one of those scientific plurals that sounds mysterious but is just following ancient Latin grammar rules.
