Habitat & Geographic Range

Commerson s Dolphin

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Common Marsh-Mallow

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, montane grasslands and shrublands, and temperate coniferous forests, among 6 distinct biome types spanning the Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Algeria), Asia (India), Europe (13 countries), North America (Canada, United States), and South America (Peru). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Commerson s Dolphin

<em>Cephalorhynchus commersonii</em>, commonly known as Commerson's Dolphin, is a small cetacean in the family Delphinidae. This species is classified as Least Concern on the IUCN Red List and is notable for its striking black-and-white coloration, which makes it one of the most visually distinctive dolphin species. Commerson's Dolphins typically inhabit coastal and nearshore marine environments of the Southern Hemisphere, particularly around the Falkland Islands, the southern tip of South America, and a geographically isolated population near the Kerguelen Islands in the Indian Ocean. These dolphins are highly social animals, often observed in small groups engaging in acrobatic behaviors near the surface. They typically feed on fish, squid, and crustaceans, often hunting cooperatively in shallow waters and kelp beds. Their average lifespan is approximately 18 years, and they are known for their fast, energetic swimming. Commerson's Dolphins are sometimes caught as bycatch in fishing nets, posing a localized conservation concern despite their overall Least Concern status.

Common Marsh-Mallow

<em>Althaea officinalis</em>, the common marsh mallow, is a tall perennial herb in the family Malvaceae, native to Europe and western Asia and now widely distributed across Africa, Asia, Europe, North America, and South America. It is classified as Near Threatened on the IUCN Red List. This species typically grows in saltmarshes, brackish ditches, damp meadows, and coastal habitats, and is also cultivated in gardens for its ornamental and medicinal properties. Common marsh mallow produces pale pink, five-petalled flowers and lobed, velvety leaves covered in soft hairs. It has a long history of medicinal use, with roots, leaves, and flowers employed to soothe mucous membranes and treat respiratory and digestive ailments. The original marshmallow confection was prepared from the mucilaginous root extract of this species. It grows in a range of biome types including grasslands, wetlands, and forest edges. Habitat loss, particularly of coastal wetlands, represents the primary pressure on populations across its native range.
