mr willy,
They are about 5 feet long.
From what I have been reading, gators only eat what they can swallow whole. They don�t have the ability to shred and chew (like you see on crocodile hunter), their stomach juices help them digest food. The biggest threat to humans is when they are fed; they learn to associate food with humans and expect a handout. They may snap at your hand (or other parts) mistaking it for food.
I have not fed my gators.
(good idea on the signature)
