Common Apple Snail

<em>Pomacea bridgesii</em>, commonly known as the Common Apple Snail or Spike-topped Apple Snail, is a freshwater gastropod mollusk in the family Ampullariidae. This species is classified as Least Concern on the IUCN Red List and has an extensive global distribution spanning Asia, Europe, North America, and South America, largely due to its popularity in the aquarium trade and subsequent introductions. In its native South American range, Common Apple Snails typically inhabit tropical and subtropical freshwater environments including rivers, lakes, marshes, and flooded forests such as mangroves. They are known for their distinctly globular shell and their ability to breathe both air and water using a combination of a gill and a primitive lung-like structure. This species typically lays distinctive pink egg clutches above the waterline on emergent vegetation or hard surfaces. It feeds primarily on aquatic vegetation, algae, and detritus. Its average lifespan is approximately 3 years under favorable conditions.
