What kind of snake is Kurt Russell's stomach tattoo in the film "Escape from New York"?

S. D. Bob "Snake" Plissken is a character who is a protagonist in the films "Escape from New York" (1981) and "Escape from L.A." (1996). Portrayed by Kurt Russell, the character was created by John Carpenter and Nick Castle. An antihero, Plissken is a former US Army Special Forces lieutenant who served in the Soviet Union during World War III, for which he was awarded two Purple Hearts, before turning to a life of crime. In both movies, Plissken is approached by the federal government of the United States, which offers to pardon him if he agrees to carry out dangerous missions in New York City and Los Angeles, both of which have been transformed into maximum security prisons to deal with a massive increase in crime.

Snake is shown as being very cynical, most likely due to the hypocrisy of the US government; he appears however to be willing to do anything to survive. He is often seen by others to be somewhat of a misanthropist. He is terse, stern in his speech, of few words, and holds nothing sacred or even important. He does however have a very loose code of honor.

Plissken frequently shows coolness and level-headed thinking in extremely stressful situations. Although he will kill without remorse or hesitation, he does not kill for fun or when it is unnecessary. He is also known for his quick wit and gallows humor. To represent a true persona, Plissken has a tattoo of a cobra on his abdomen and he is exalted by skills in martial arts due to military training.
