Habitat & Geographic Range

Common Apple Snail

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and mangrove forests and coastal wetlands within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Israel, Taiwan, Vietnam), Europe (Austria), North America (United States), and South America (Chile, Venezuela).

Great Reed Warbler

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Distributed across Belgium, Denmark, Luxembourg, Norway, and Sweden. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Great Reed Warbler

Great Reed Warbler (Acrocephalus arundinaceus) is classified as Critically Endangered (CR) on the IUCN Red List. Facing an extremely high risk of extinction in the wild due to severe population decline and habitat loss.
