sentence: Toads have paratoid glands behind their eyes which are used to make poison.
sentences_before: All toads are frogs, but not all frogs are toads. Toads mainly evolved in dry climates, so many toads have rougher, browner skin. Many toads also burrow, though that depends on the environment that the toad evolved in. Toads lay eggs in strings attached to rocks, unlike true frogs which lay eggs in a jelly-like mass. Also, toads generally have shorter legs and fatter bodies.
sentences_after: The poison is not harmful to humans.
