The eggs of fish and amphibians are jellylike. Cartilagenous fish (sharks, skates, rays, chimaeras) eggs are fertilized internally and exhibit a wide variety of both internal and external embryonic development. Most fish species spawn eggs that are fertilized externally, typically with the male inseminating the eggs after the female lays them.
Another method of extracting caviar is by removing eggs through a small incision, which allows the female to continue producing roe. [54] Other farmers use a process called "stripping", which extracts the caviar from the fish via a small incision made along the urogenital muscle when the fish is deemed to be ready to be processed.
In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo.

Human embryonic development covers the first eight weeks of development, which have 23 stages, called Carnegie stages.
