Habitat & Geographic Range

Coelacanth

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 8 distinct biome types spanning the Australasia and Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Comoros, Indonesia, Mozambique, and South Africa. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Dwarf Mongoose

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Common Dwarf Mongoose

<em>Helogale parvula</em>, the common dwarf mongoose, is the smallest mongoose species in Africa and belongs to the family Herpestidae. Classified as Least Concern by the IUCN, the species maintains stable populations across diverse terrestrial and aquatic habitats throughout sub-Saharan Africa, though specific geographic range data for this entry are limited. <em>Helogale parvula</em> is a highly social carnivore that typically lives in cooperative family groups of up to thirty individuals, led by a dominant breeding pair. The group structure supports cooperative foraging, pup-rearing, and sentinel behavior, with designated individuals standing watch for aerial and terrestrial predators while others forage. Common dwarf mongooses are diurnal and typically shelter in termite mounds, rock crevices, or hollow logs, moving between multiple den sites within their territory. They play an important ecological role as predators of insects, small vertebrates, eggs, and other invertebrates, contributing to the regulation of prey populations in savanna and woodland ecosystems. Their mutualistic associations with hornbills, in which both species benefit from shared foraging and predator detection, are among the most studied interspecific relationships in behavioral ecology. Biological traits of this species remain poorly documented in the scientific literature.
