Sadly, because of irresponsible media portrayal of ALL of the large snakes, questions like your's arise. Temperament when it comes down to it is based on an individual snake by snake basis. I've heard people say King Snakes are terribly flighty and prone to bite as are Carpet pythons. But I've seen people who keep both say otherwise. I've handled Carpets and have been very impressed.

My Barranquilla Colombian boa is settling down, but compared to our Royal python he's been more of a handful. That will change.

Any snake can make a mistake and once it does, "media" will automatically make it a mean snake. They won't report that the person that got bitten was recently petting a rabbit or a dog or had blood from a rat on them. Just that the snake bit them.

The "super snake" is also BS. Each species has individual characteristics that help it survive and thrive in a certain area which is why the range of different snakes varies. Hybridization will often make adaption more difficult. Who's care sheet do you follow when you combine 2 separate species? And then can the hybrid reproduce? Usually its rare, but possible. The Florida scare is somewhat over blown. A lot of the snakes, but not all still fall victim to the elements, and will never survive much further north of where they are.

Retics will be your longest snake. However the girth of the body is less than the anaconda and which also gets close to the lengths of the Retic.

African Rock's come in the Central species (larger) and Southern species. They are also huge, long and thick.

Burmese and Indian Rock pythons are very thick and can be long. While not as long as retics they are quite heavy bodied.

Anaconda's are the heaviest of the snakes and can attain lengths close to the retic. The Green form is much larger than the yellow.

There are so many pythons that can be discussed.

Australian pythons (there are many) can get huge as well. Scrub pythons and Olive pythons can be very long yet less heavily bodied. Scrubs can be considered aggressive but I'm sure like most, somebody out there has a docile one.

I'd highly recommend reading BOAS AND PYTHONS OF THE WORLD By Mark O' Shea a leading herpetologist and snake guru.

Almost anything you see on TV will contain such poor info you will get confused.

I'm no expert, but have researched a great deal. You can find a lot of people who keep each species of these snakes that can shed more light.

I'd say the meanest snake will be the one that bites me the hardest when I'm not expecting it LOL!
