Answer #1

ANSWER:

In the majority of species of amphibians, fertilization is external. this is often conjointly common among bony fishes and shows that the genital system and embryonic development of amphibians are familial from Osteichthyes.

Curiously, though they use external fertilization, amphibian males and females join to stimulate the discharge of sperm cell and egg cells. This development isn't classified as internal fertilization, since the gametes unite in water.
