Habitat & Geographic Range

Buckelwal

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

clear glass snail

Habitat

Typically found in terrestrial and aquatic habitats including forests and freshwater.

Range

Distributed across France and Italy. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

clear glass snail

Clear Glass Snail 2 refers to a second species sharing the common name 'clear glass snail,' likely a distinct taxon within the families Vitrinidae or Gastrodontidae that shares the characteristic translucent, thin-walled shell morphology. Translucent-shelled land snails in these families are distributed across temperate zones of the Northern Hemisphere, with centers of diversity in Europe and North America. Many species in these families are restricted to specific microhabitats characterized by stable humidity and abundant organic matter, such as old deciduous woodland, valley mires, and calcareous grassland with a dense ground flora. These snails graze on the surface film of algae, fungi, and bacteria on dead wood and leaf litter, contributing to nutrient cycling in the leaf-litter layer. The glassy or semi-transparent shell is a shared evolutionary feature across multiple lineages, reflecting convergent adaptation to moist, shaded environments where predation pressure may differ from open habitats. Many glass snails are poorly documented in terms of population size and trends. Conservation concerns for thin-shelled snails typically center on habitat destruction, desiccation from climate change, and acidification of soils that reduce the calcium carbonate availability necessary for shell formation.
