Several people have offered you help - Google. That's the best advice there is. You may actually learn something about some of these snakes while you are at it.
Do you really think that most people can name - out of 26 python species, 11 python subspecies, 28 boas species and 36 boa subspecies - all of those that stay under six feet? That's a total of 101 snakes.
I had to use Google to even find out how many total species and subspecies there were.............
Use Google to either refine your question or find the answer yourself.
