Put the tortoise back where you found it, and don't show those pics around. I'm pretty sure there are fines for even handling that species.
There are a few venomous snakes near Orlando:
water moccasin- thick black snake, mostly aquatic, bright white inside of mouth.
Pigmy and eastern diamondback rattlesnake- they have rattles, keeled scales, sandy color
Copperhead(usually further north)- hard to describe, thick bodied like moccasin, rusty head
Coral snake- red and yellow kill a fellow..... (black nose)
I think that's it...did I forget any?
