Do red bellied toads have poison?

I believe you mean fire bellied toads. FBT's have poison glands on the side of their heads. They look like small bulges. They can also have them on their upper back. If the toad is not green, the poison glands on their back are light green. You can see poison as a yellow color in their water if left unchanged. The toads squirt out poison if they feel that they are in danger.
