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 Bunomys

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Coelacanth

A living fossil thought extinct for 65 million years until rediscovered off South Africa in 1938, coelacanths can reach 2 meters and 90 kg. They belong to an ancient lobe-finned lineage more closely related to tetrapods than to ray-finned fish, making them scientifically invaluable for understanding vertebrate evolution. Found in deep rocky reef habitats of the Indian Ocean, they are nocturnal and undergo internal fertilization, giving birth to fully formed live young. Critically Endangered.

Common Bunomys

The common bunomys (<em>Bunomys chrysocomus</em>) is a small rodent species found in diverse terrestrial and aquatic habitats, including tropical forests and adjacent ecosystems. This species is classified as Least Concern on the IUCN Red List, reflecting a currently stable population without immediate conservation concerns. As a member of the family Muridae, the common bunomys is an endemic rodent of Sulawesi, Indonesia, where it typically inhabits montane forest environments at moderate to high elevations. The species often forages on the forest floor, feeding on seeds, fruits, fungi, and invertebrates. Its diet and foraging behavior make it an important contributor to seed dispersal and nutrient cycling in its native forest ecosystems. The common bunomys is typically nocturnal and solitary in its habits, as is characteristic of many rodents in its genus. Biological traits of this species remain poorly documented in the scientific literature.
