For additional meanings of Anthony, please see Anthony (disambiguation).
Anthony was a seemingly amphibian passenger aboard the Osler who was headed for "The Farm" on Endicronimas V.
In 2380, the other passengers aboard the Osler presumed that Anthony used to be a male Starfleet officer, that through some medical mystery was turned into a salamander-like creature that couldn't talk. Like the other passengers, Starfleet sent him to the medical spa on Endicronimas V so that medical specialists there could figure out how to treat him.
Once settled in at The Farm, Anthony enjoyed a massage by the swimming pool. (LD: "Much Ado About Boimler")
Anthony's raspy breathing was provided by an unknown performer.
Anthony's appearance bore a very strong resemblance to the hyper-evolved amphibians that Tom Paris and Kathryn Janeway became in the Star Trek: Voyager episode "Threshold".
