Oneirodidae (Dreamers)
Etymology: Oneirodes: Greek, 'oneiros' = a dream or dreamlike or out of a dream (suggesting this fish is so strange and marvelous that can exist only in dreams) (Ref. 86949); alius: The name alius is an adjective in apposition from the Latin, meaning another, alluding to the seemingly never-ending number of new forms being discovered within the genus..
