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).
Eponymy: Alfred Post (d: 1935) is a German zoologist who worked at Hamburg’s Institut für Seefischerei. He was honoured for his contributions to our knowledge of deep-sea fishes and his continuing services to the ichthyological community. (Ref. 128868), visit book page.
