Are mystery snails also apple snails? Or are they different types of snails?
A: In some sources the name apple snail and mystery snail are considered to be synonyms for the snails of the family
Ampullariidae. The name apple snail refers to there size, colour and form, while the name mystery snail comes from the fact that the aquarium market didn't know what kind of snail it was or where it came from, so it was a mystery (snail) for them.
In other sources, the mystery snails are described as snails from the family
Viviparidae. The snails from this family look very similar to the snails from the family Ampullariidae, but they do lack a
lung and
labial tentacles and are livebearing snails (hence the name
Viviparidae).
Most snails sold as 'mystery snails' in the shops are
Pomacea bridgesii snails.
