Morphology

Rheidae = rhea (opaque) = rhea + idae

Formally composed of 'rhea' + the taxonomic suffix '-idae', but understanding that '-idae' means 'family' requires specialized biological knowledge and is not obvious to average learners.

Etymology

Rheidae comes from the bird name rhea plus the scientific ending -idae, which marks an animal 'family' or group. So Rheidae simply means the family of rheas, the large flightless birds native to South America.
