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.

Commerson's Leaf-nosed Bat

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.

Commerson's Leaf-nosed Bat

<em>Macronycteris commersonii</em>, commonly known as Commerson's Leaf-nosed Bat, is a chiropteran mammal in the family Hipposideridae. This species is assessed as Near Threatened on the IUCN Red List, indicating that it faces increasing pressures that could elevate its risk of extinction without conservation attention. Commerson's Leaf-nosed Bat typically inhabits a range of diverse ecosystems across sub-Saharan Africa, including forests, savannas, and areas near caves or rocky outcrops that serve as roosting sites. Like other hipposiderid bats, it uses echolocation to navigate and hunt in low-light conditions, often foraging for insects in open or semi-open environments after dark. Roost disturbance, habitat degradation, and human persecution are among the primary threats facing this species. The large, elaborately shaped noseleaf characteristic of the family helps focus echolocation signals during foraging. Populations are typically found roosting in caves, mines, and hollow trees in groups that may range from small colonies to large aggregations. Biological traits of this species remain poorly documented in the scientific literature.
