What do poisonous toads look like?
Most true toads (family Bufonidae) are poisonous. Bufonids are generally large, brown, warty and rather ugly. Behind the eyes, on top of the head, are two large glands called paratoid glands, and these secrete a toxin known as bufotoxin (it also has several other names.) The larger the glands the more toxic the toad, generally. There are no other identifying factors. Poisonous frogs, particularly the batrachid frogs (Phyllobates, Dendrobates, Epipedobates species amongst others) are generally brightly coloured. Throughout nature, this signal means, I don't have to hide from you because I'm poisonous. Don't eat me.
Well they are brownish. they have big chubby cheeks where they keep their poison they are all different sizes. But other than all that they look like frogs
Some toads are poisonous, but most aren't.
