The Benthans were a warp-capable species from Benthos in the Delta Quadrant. They were encountered in 2374 by the USS Voyager when Lt. Tom Paris was attacked by the Benthan Guard in the Kotaba Expanse. (VOY: "Vis à Vis") It was never made clear whether it was Steth or Daelen who was a Benthan, or if neither or even both of them were. The Benthans appear in Star Trek Online, where they are modeled after Steth's species.
