                                                          Bufo toads have  glands on their head that secrete bufotoxin, a hallucinogen. When stressed, their skin weeps a poison that could harm a person. The poison is intended to deter other animals from eating the bufo toad. If you wash your hands after handling it, the bufo toad is not dangerous to pick up.
