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.

Club-tailed Cruiser

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Found in Taiwan.

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.

Club-tailed Cruiser

Macromia urania is a large dragonfly in the family Macromiidae, known as a cruiser dragonfly due to its patrolling flight behavior along watercourses. The genus Macromia is characterized by metallic greenish or yellowish markings on a dark brown or black body and bright green eyes. M. urania is native to East Asia, with records from Taiwan and adjacent parts of the East Asian region. Macromiid dragonflies breed in clean, flowing rivers and streams with good water quality, where larvae are benthic predators in swift-flowing sections. Adults are powerful, fast-flying insects that cruise steadily along forest streams and rivers, males holding territories over suitable breeding sections. Females oviposit in flight by tapping the water surface. Macromia species are generally indicators of good water quality and habitat integrity, as their larvae are sensitive to pollution and siltation. M. urania is listed as Least Concern by the IUCN. Broader threats to dragonflies in the region include water pollution, dam construction, and water abstraction, which degrade the flowing water habitats essential for Macromia reproduction.
