Death by salamander

[snopes]

Comment: My daughters love your show and I
was talking to them the other day about a rumor I heard many years ago
while surving at Ft. Bragg when I was a soldier. The myth goes like this.

A soldier was dared to eat a salamander whole and alive. you know just
swollow it. Which he did. A couple of days later the soldier went on sick
call due to severe pain in his stomach and side. when he was x-rayed it
was found that the salamander was still alive and eating himself free.

Any truth to this myth and can the salamander survive this type of
enviroment?
