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.

Cluster-head Protea

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.

Cluster-head Protea

Protea welwitschii, commonly known as cluster-head protea, is a flowering shrub or small tree in the family Proteaceae, a family renowned for producing some of Africa's most spectacular blooms. Found across savanna woodlands and grasslands in central and eastern Africa, this protea inhabits well-drained, often sandy or rocky soils in open miombo woodland systems and adjacent grasslands. The species produces globose to cylindrical flower heads with characteristic bracts, typical of the genus, which attract sunbirds and other nectarivores. Protea welwitschii is adapted to fire-prone ecosystems, where periodic burning stimulates regeneration and maintains the open habitats the species requires. The Proteaceae family, concentrated in the Cape Floristic Region and Australia, represents an ancient lineage dating to the Gondwana supercontinent. Unlike the more famous Cape proteas, P. welwitschii occupies tropical African biomes extending from Angola and Zambia through Tanzania and Kenya. It is assessed as Least Concern by the IUCN. The plant plays an ecological role as a nectar source in African savanna systems where flowering plants that bloom in the dry season provide critical resources for pollinators and nectarivores during periods of food scarcity.
