Open encyclopedia reference
Agrostichthys parkeri, also called the streamer fish, streamerfish, or Benham's streamerfish, is a species of oarfish. Only seven identified specimens have been examined, with few found fully intact, and have mainly been found in the Southern Ocean. Agrostichthys parkeri belongs to the Regalecidae (oarfish) family in the Lampriformes order and is the only known member of its genus. This species has been known to grow up to 3 metres (9.8 ft) long and has a ribbon-like body, two large eyes, a protruding mouth and long filamentous rays originating at the head. Due to only seven specimens being found, only the distribution and anatomy of Agrostichthys parkeri can be documented.
