Nerite snail eggs are designed to stay dormant until specific seasonal conditions submerge them in tidal brackish water. Once in brackish water, the eggs hatch.
Nerite snail babies are different than other types of snail species in that they don’t look like snails when they initially hatch. Upon hatching, they are larvae. Once the larvae make their way to true seawater, they receive the appropriate salinity that is necessary to transform them into the snail stage. The young snails return to tidal areas where the water is brackish, and these surroundings allow them a larger area in which to forage, live and flourish.
