Frogs are amphibians and as such have an aquatic larval stage. This is followed by a metamorphosis into the adult terrestrial form. Most frogs lay their eggs in water where the larvae develop. Although a few species are ovoviviparous meaning they hatch from the eggs inside the mother’s body most species lay their eggs in water where they are fertilized externally by the male.
The time of year when frogs lay their eggs varies depending on the species but is generally timed to coincide with the availability of food for the tadpoles. In temperate regions this is usually in late winter or early spring while in tropical regions it can be year-round.
The number of eggs laid also varies by species but can be quite large. For example the common frog (Rana temporaria) can lay up to 12000 eggs at a time!
When the eggs are laid the male will often stay with the female to help protect them. He will use his body to keep predators away and may even help aerate the eggs by fanning them with his hind legs.
Once the eggs hatch the tadpoles must fend for themselves. They will feed on algae and other small organisms in the water. After a few weeks or months (depending on the species) they will undergo metamorphosis and emerge as adult frogs.
So when do frogs lay eggs? It depends on the species but generally speaking they will lay their eggs in water in late winter or early spring. The number of eggs can be quite large with some species laying up to 12000 at a time!
