The snails can produce as many as two hundred offspring from one egg-laying event. Sometimes not all the eggs are fertilized so they do not all hatch. When they do hatch, the hatchlings run the risk of being eaten if they share an aquarium with fish. [5] Hatchling mystery snails will grow quickly if given an appropriate amount of food and calcium.
Pomacea diffusa was originally described as a subspecies of Pomacea bridgesii. [1] Pain (1960) [2] argued that Pomacea bridgesii bridgesii was a larger form with a restricted range, with the smaller Pomacea bridgesii diffusa being the common form throughout the Amazon Basin (Brazil, Peru, Bolivia).

Pomacea is a genus of freshwater snails with gills and an operculum, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. The genus is native to the Americas; most species in this genus are restricted to South America.
First eggs are laid in or near the natural orifices of the head and anus, as well as at the site of perimortem wounds. [2] Depending on the rate of decomposition and the development time of particular blowfly species, eggs may hatch and young larvae begin to feed on tissues and liquids while the carcass is still classified in the fresh stage.

[6] [15] Females can brood more than one batch of young at a time, and the number of young in one brood is positively related to the size of the female. [16] Reproductive females are usually larger than 16 mm. [ 17 ] Female banded mystery snails live 28–48 and males live 18–36 months.
Viviparidae, sometimes known as the river snails or mystery snails, are a family of large aquatic gastropod mollusks, being some of the most widely distributed operculate freshwater snails. This family is classified in the informal group Architaenioglossa according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005 .
Once laid, the eggs take approximately two weeks to hatch, during which time the bright pink or orange coloration of the eggs fades. [ 23 ] First direct evidence (of all animals), that proteinase inhibitor from eggs of Pomacea canaliculata interacts as trypsin inhibitor with protease of potential predators, has been reported in 2010.
A snail farm near Eyragues, Provence, France. Heliciculture, commonly known as snail farming, is the process of raising edible land snails, primarily for human consumption or cosmetic use. [1] The meat and snail eggs a.k.a. white caviar can be consumed as escargot and as a type of caviar, respectively. [2]
