Frogs use external fertilization.
both mates will excrete mucus out of their bodies... the mucus contains their sex cells... therefore, the male and female mucus will mix up and causes fertilization.
External, the female lays eggs onto small braches, leaves or rocks in a pond/ river or close to a water source, the male then fertilizes them (externally), in most cases as the female is laying the eggs

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.
