from The Century Dictionary.
- noun An animal that feeds mostly or entirely by night; specifically applied to the bird Nyctiornis amictus. Most fishes are said to be night-feeders, yet all of them feed more or less in the daytime.
Sorry, no etymologies found.
The conger eel (_Conger vulgaris_) is another night-feeder, which gives fine sport, as it grows to a great size, and is very powerful.
