Fertilization
It has something to do with the fecundity of the organism. Some organisms release only one egg at a time, so only one egg gets to be fertilized. Smae goes with the animals that release multiple eggs at once, the eggs can be fertilized all at the same time.
The ovary is the egg-producing gonad found in female animals.
Egg-born animals are called oviparous animals. Such animals include snakes, chickens, birds, crocodiles, fish, insects and animals from the monotremata order.
There are many types of egg laying animals. Pictures of these animals can be found in an image search from a search engine.
The general name for egg-laying animals is that they are 'oviparous animals'. The Order of egg-laying mammals are known as 'Monotremes'.
Almost all animals begin as an egg and a sperm. There are a few exceptions, though, such as sea sponges. But for the majority, they begin as sperm and egg.
