Is fertilization in amphibians external or internal? Regarding this aspect, are amphibians evolutionarily closer to fish or to reptiles?
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.
