The senior geologist of the Enterprise, a lieutenant who joins the landing party on an artificially built planet and is killed by the touch of the mysterious Losira.
Lieutenant D'Amato is the ship's senior geologist in the third-season Original Series episode That Which Survives. He was played by Arthur Batanides.
He beams down with Kirk, McCoy and Sulu to examine a planet that appears far younger than its vegetation and atmosphere should allow. A violent quake follows and the Enterprise is flung almost a thousand light years away, stranding the four men.
While surveying alone, D'Amato is approached by a beautiful woman who knows his name and tells him she is for him. Her touch kills him instantly; McCoy finds that every cell in his body has been disrupted. Unable to dig a grave in the planet's hard alloy surface, his companions bury him under a cairn of stones.
