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.

Coastal Silver Mallee

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.

Coastal Silver Mallee

Coastal silver mallee (Eucalyptus ecostata) is a multi-stemmed mallee eucalyptus in the family Myrtaceae, endemic to the southwest of Western Australia, where it grows in coastal heath, scrub, and mallee shrublands on sandy or lateritic soils near the Indian Ocean coast. Like other mallees, it regenerates vigorously from a lignotuber after fire, a critical adaptation in fire-prone Mediterranean-climate vegetation. Leaves are silvery-grey on young growth, giving rise to the common name, while older foliage is greener. The species produces creamy white to yellow flowers that attract native bees and honeyeaters. Eucalyptus ecostata is assessed as Near Threatened by the IUCN, reflecting a restricted range in the Southwest Australian Floristic Region—one of the world's biodiversity hotspots—and vulnerability to habitat clearing for agriculture, altered fire regimes, and invasion by introduced weeds such as Phytophthora cinnamomi, a root pathogen that has devastated many Australian plant species. Conservation efforts in the region focus on protecting remnant coastal heath and mallee vegetation within the Southwest's network of national parks and nature reserves.
