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.
Viviparus georgianus, common name the banded mystery snail, is a species of large freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Viviparidae, the river snails. This snail is native to the southeastern United States.
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.
In this family of snails, the male phase ends in December, followed by an egg maturation phase, and ends with oviposition, the act of laying eggs during May of the following year. Phylogenetic evidence for this is present based on the overall condition of the gonads especially in the degree of development of the genital ducts. [7]
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).

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 .
Ramshorn snails are hermaphroditic; [3] [4] two organisms of any sex have the ability to breed and produce offspring. Ramshorn snails lay eggs in globules, which tend to be brownish in color. The globules contain about a dozen or so eggs, though it can vary. The globules are translucent, so it is possible to visually see the new snails develop ...
The egg masses of Pomacea canaliculata are a bright pink or orange in color Eggs of Pomacea canaliculata, scale bar in cm (25 ⁄ 64 in). In temperate climates, the egg-laying period of this species extends from early spring to early fall. [22] while in tropical areas reproduction is continuous.
