Dusty, I've got a couple questions.

What snakes are you aware of that have been extirpated by the pet trade?

Or when you say "snakes" do you just mean localities, not actual "snakes", as in a whole species or subspecies?

Lastly what does "overcollected" mean, as defined by the authors(Halliday's and Adler's Encyclopedia of Reptiles) you cited?
