Jungle Jag Size

[Will0W783]

Maybe this is a dumb question, but I was under the impression that coastals are the largest carpet subspecies, so wouldn't a jungle/jag be expected to be the same size or smaller than a "straight" (pure coastal) jag? Maybe I'm just reading the thread wrong, but it sounds like marvelfreak is saying he expected them to be larger because they were part jungle? The research I've done suggests jungles average around 5-6 feet, while coastals can be 8-9 and Irian Jayas usually 4 1/2-5. Although with better knowledge of optimal care and medicine to allow our snakes to live longer, it would make sense that all species of snake attain a larger average captive size than a few decades ago.
