Note: The record tagged the snake's captivity as "caught" (as opposed to "killed").
The longest recorded known catch of a Cottonmouth snake is six foot one and a half inch, that measured two and a quarter inches across the head and 10 inches round, found at Orange Lake, FL.
While there has been no formal record established, there's a claim that a 74-inch Cottonmouth snake (a bit longer than the one mentioned above), previously thought to be 7 feet, has been found in Baldwin, Florida. Watch the video at LingAlongsideWildlife.com.
