Big snake, yes?
According to snopes.com it is an olive snake, which can grow from 8 to 12 feet long.
The creature it is pulling out of the water appears to be bovine (that means a cow) but it actually a wallaby. Still a formidable meal, but one that pythons consume rather often.
According to the snopes article, the python tried for an hour to pull the big meal up, but in the end was unable to accomplish the feat.
