Frogs can lay tens of thousands of eggs whereas others lay just the smallest number of eggs. Most of the frogs abandon their eggs shortly after they mate. This is the reason they lay hundreds of eggs. The method of fertilization used by fish and frogs is called external fertilization i.e fertilization occurs outside of the body. Therefore, fish and frogs produce an enormous amount of eggs annually to counteract the possibility factor(sperm to come into contact with eggs) and then produce offspring. Another reason for this is there are a lot of organisms that feed on eggs, therefore a greater quantity of eggs means the possibility of birthing youngsters.

So, frogs lay their eggs in water to keep them from becoming dry. Another reason why frogs lay eggs underwater is that the tadpoles coming out after hatching are equipped with gills as the only organ which requires them to swim underwater in order to breathe. Basically, gametes are sexual cells. It is necessary to have sex cells such as eggs and sperm, to reproduce. Frogs, like numerous other species that are at the heart of the food chain, produce massive amounts of gametes.

Evolution has helped them produce this, allowing them to keep their population at a steady, healthy level. Frogs are prolific producers of gametes simultaneously. Because they are close to the very bottom of the food chain to ensure the future of their species, when reproducing, they do it in huge numbers. Therefore, only a handful of progenitors will survive sometimes. While the eggs of toads are tethered to leaves or grass near the water’s edge and are arranged in long, parallel strands, which resemble beads made of black, frogs scatter their eggs over water surfaces in huge, circular clusters.

The embryos that are in the eggs of frogs look like black spots that are situated in the middle of clear gel-like globes. Like all creatures that live short Frogs are often breeding and laying eggs in order to advance their species to the greatest extent possible. If they’re playing in your backyard swimming pool, there’s a high chance they’re depositing eggs in the pool’s water.
