Oh, if you don't know what kind of snake that is, it's a coral snake. Deadly venomous, yet there have been no recorded deaths from their bite (at least not in Florida). They are in the same family as cobras, but are rear-fanged. They have to get a really good mouthful and chomp down hard to inject their venom.
But really, they are pretty shy creatures who just try to scoot away as quick as they can.
