When frogs breed, fertilized eggs hatch in water. Frogs are amphibians. They reproduce by laying eggs. March-April is the breeding season of frogs every year. At this time, the female frog and the male frog will produce eggs and sperm into the water, and then the eggs and sperm will combine into fertilized eggs in the water. These fertilized eggs developed for about 10 days and became tadpoles. At this time, they can only live in water, and they can only move on land when they grow into frogs. 1. Are frogs oviparous? Frogs are amphibians, usually called amphibians. Egg-laying animals are the result of dividing animals from the way of reproduction, and animals that reproduce their offspring by laying eggs are egg-laying animals. Amphibians breed in a unified way, that is, they lay eggs, and frogs are no exception. Therefore, frogs also belong to one of the oviparous animals.

As an oviparous animal, frog's specific reproduction mode also accords with the characteristics of oviparous animals. The breeding season of frogs usually begins from March to April every year. In this season, male frogs will first attract the attention of females through their own calls, find a suitable mate and urge them to lay eggs in the water. Then the male will also produce sperm in the water. Frog eggs and sperm are fertilized in vitro. Then these fertilized eggs will hatch into tadpoles, which is the larval stage of frogs.

2. Where does the fertilized egg hatch when the frog breeds? As mentioned above, frogs reproduce by laying eggs. After female and male frogs lay eggs and sperm in water, these eggs and sperm will develop into fertilized eggs. This process is done in water. The fertilized egg will gradually develop into a tadpole, which takes about 10 days. Tadpoles live in water, but not on land, because they breathe through gills and feed on plankton in the water. When they transform into frogs, they can live on land.
