Non-venomous snakes: Do they have fangs?

I would like to thank the OP for using the word “venomous” instead of “poisonous.”

I don’t know why. Any snake that is venomous is by definition also poisonous. Venomous is very slightly more accurate but even the pedants here at SDMB wouldn’t quibble over the difference.
