A genus of freshwater mussels; a region or realm of the upper air or heavens (poetic/philosophical).
Latin/scientific, from Greek aether (upper air). In biology, named to evoke the ethereal nature of these aquatic organisms.
Etheria is actually a real genus of African freshwater mussels that live in the Nile River — scientists often name organisms based on poetic associations with their qualities, so these light-shelled mollusks got a heavenly name.
