Detailed explanation-1: -Unlike other tetrapod vertebrates (reptiles, birds, and mammals), amphibians do not produce amniotic eggs. Therefore, they must lay their eggs in water so they won’t dry out.
Detailed explanation-2: -Frogs ignore their eggs completely after mating. Note: Though almost all amphibians lay their eggs in water, there are some species like the Pristimantis genus of frogs which lay they legs on land.
Detailed explanation-3: -∙ Aquatic animals like fishes and frogs lay their eggs in water.
Detailed explanation-4: -As the chance of fertilization is nature dependant i.e it depends on the movement of water for the sperm to come in contact with the egg. Thus the fish and frog produce a huge number of eggs each year to overcome the chance factor(sperm to come in contact with egg) and produce offsprings.
