YOU MIGHT BE RIGHT IN THAT TAKE
But what I have said before is it is not realistic for anything than an boa or python to swallow a human and anything else is total fantasy and I
write realistic sci-fi/horror.

The garter snake,though an non venomous
snake in terms of us humans,but each of
the snakes have some type of venom that
they inject into their prey..even the
garter snake,rat snake,gopher etc.But
it is much smaller amounts since it
is rear fanged and does not have the
sacks etc...as they inject a smaller
amount in and mostly wrap up and then
constrict.

So if an 28-31 foot python was to try to
swallow a human..what would be the razor
teeth damage on a human and that is depended
on the jaw unlocking and the size of the
head of the snake and being able to unlock
its jaw to a size to fit over the human
meal.So you are right about that also but
there are few big snakes in this world as
big as that and I did see an 27.5 foot
Green Anaconda in the Amazon basin but
that was one huge snake(that the one that
came after us).
