Frogs have external fertilization.
The modes of fertilization vary. Most frogs practice external fertilization, the females laying eggs in water and the males spraying sperm over them. Primitive salamanders have external fertilization, but most have internal fertilization, with the female taking up the male's spermatophore. All caecilians have internal fertilization, and the male deposits sperm in the cloaca of the female by using the end of his cloaca as an intromittent organ.
