The larger yolk content of the mesolecithal eggs allows for a longer fetal development. Comparatively anatomically simple animals will be able to go through the full development and leave the egg in a form reminiscent of the adult animal. This is the situation found in hagfish and some snails.
The egg is not retained in the body for most of the period of development of the embryo within the egg, which is the main distinction between oviparity and ovoviviparity.

Six small non-avian dinosaur eggs, no bigger than grapes, were discovered during a field study in Ganzhou, China, in 2021. These eggs now mark the smallest-ever found in the world.
Human egg cell. The egg cell or ovum (pl.: ova) is the female reproductive cell, or gamete, [1] in most anisogamous organisms (organisms that reproduce sexually with a larger, female gamete and a smaller, male one). The term is used when the female gamete is not capable of movement (non-motile).
The creatures were found in “absolutely lightless” areas of forest caves, researchers said. ‘Giant’ cave-dwelling creature — carrying 6 eggs — found in Ecuador. It’s a new species
