Lieutenant Clayton is an Enterprise officer in The Ambergris Element who pilots the aquashuttle on Argo and is aboard when a sur-snake attacks it.
Lieutenant Clayton appears in the Animated Series episode The Ambergris Element. He is part of the small team that goes down to the ocean planet Argo in the aquashuttle with Kirk, Spock and McCoy to study its seismic activity.
A giant sur-snake attacks the craft. McCoy and Clayton are thrown clear and recovered, but Kirk and Spock go under with the wreck and are missing for days.
Clayton takes part in the search and is with McCoy when the two officers are found on the shore, alive but with webbed hands and unable to breathe air. He helps in the later efforts to keep them in water on the ship and to work with the Aquans towards a cure.
