Subspecies

  • Pomacea bridgesii bridgesii (Reeve, 1856)
  • Pomacea bridgesii diffusa (Blume, 1957)

Anatomy

Mystery snails possess structurally complex eyes at the tip of a cephalic eyestalk. These snails possess the ability to regenerate the eye completely after amputation through the mid-eyestalk. They are born with both gills and lungs. [1]

Distribution

The native distribution of this snail is Bolivia, Brazil, Paraguay and Peru.

Non-indigenous distribution

It is non-indigenous in Hawaii since 1960 (Pomacea bridgesii diffusa), southeast Asia since 1980s, and Florida since the early 1980s (Pomacea bridgesii diffusa).[2]

Offspring

Mystery snails lay their eggs above the water line, which take 2 4 weeks to hatch. They can have as many as two-hundred offspring.

Human relevance

It is often kept as an aquarium pet because of its wide range of shell colors, lack of appetite for live plants, and ease of care.
