I'm continuosly fighting battles with folk on the subject of size ratios in Cottonmouths and watersnakes. I know what the "textbook" average claims, but I haven't personally experienced anything larger than 4 foot in either species. Can anyone say they've ever seen Cottonmouths or Watersnakes (any kind) as large as seven feet in this area? Larger? How about in other areas? Is it possible that max size can be expected at different lengths in different areas?
