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 Dart

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Coelacanth

1938年に南アフリカ沖で再発見されるまで6,500万年間絶滅していたと考えられていた生きた化石であるシーラカンスは、2メートル、90kgに達することができます。この種は条鰭類よりも四足動物に近い古代の肉鰭類の系統に属しており、脊椎動物の進化を理解する上で科学的に非常に重要です。インド洋の深い岩礁生息地に生息し、夜行性で体内受精により完全に形成された幼魚を産みます。絶滅危惧IA類（CR）種です。

Common Dart

<em>Andronymus caesar</em>, known as the common dart, is a butterfly belonging to the family Hesperiidae. This species occupies terrestrial and freshwater habitats, though its specific geographic range is not well characterized in current biodiversity databases. Like other members of the genus Andronymus, <em>Andronymus caesar</em> is likely associated with open woodland, savanna, and grassland ecosystems typical of sub-Saharan Africa, where many related hesperiid species are found. Adults typically exhibit rapid, darting flight patterns and are often observed perching on low vegetation or feeding on flower nectar. Larvae of closely related species are generally known to feed on grasses and related monocots, though host plant preferences specific to <em>Andronymus caesar</em> have not been thoroughly detailed in the available scientific literature. The species is assessed as Least Concern, indicating that no significant population declines or major threats have been identified. Biological traits of this species remain poorly documented, and detailed ecological and life history research would contribute substantially to understanding this taxon.
