Habitat & Geographic Range

blue whale

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 (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Star-apple

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Common Star-apple

<em>Diospyros dichrophylla</em>, commonly known as the common star apple or bladder nut, is a small deciduous tree or shrub in the family Ebenaceae, native to southeastern Africa. This species typically inhabits riverine forests, bushveld margins, rocky hillsides, and scrubby thickets in subtropical and tropical woodland regions. It is distributed across southern and eastern Africa, with populations recorded in South Africa (particularly KwaZulu-Natal and Limpopo), Eswatini, Mozambique, and Zimbabwe. Classified as Least Concern on the IUCN Red List, <em>Diospyros dichrophylla</em> remains relatively widespread within suitable habitats across its range. The species produces small edible fruits that ripen to yellow or orange and are eaten by wildlife including birds and small mammals. The flowers are white and fragrant, and the plant is sometimes cultivated as an ornamental or for its edible fruit. Biological traits such as average lifespan, body dimensions, and dietary specifics remain poorly documented in the scientific literature for this plant species. The common name "star apple" in this context refers to the star-like pattern visible when the fruit is cut in cross-section. The species is ecologically important as a food and shelter resource for local fauna in its southeastern African range.
