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.

Chuannan Crocodile Newt

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

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.

Chuannan Crocodile Newt

The Chuannan Crocodile Newt (Tylototriton pseudoverrucosus) is an Endangered salamander in the family Salamandridae, endemic to southern Sichuan and possibly adjacent regions of southwestern China. The genus Tylototriton, commonly called crocodile newts or knobby newts, is characterized by robust bodies with raised dorsolateral glands, prominent cranial ridges, and bright warning coloration — typically contrasting orange or yellow markings on a dark body — that signal the presence of potent tetrodotoxin-related neurotoxins in the skin. T. pseudoverrucosus is closely related to T. verrucosus and was described as a distinct species based on morphological and molecular differences. The species inhabits humid subtropical forest and associated streams at mid to high elevations, breeding in small water bodies and stagnant pools in forested areas. Its Endangered status reflects the ongoing destruction and fragmentation of subtropical forest habitat in southwestern China from logging, agricultural conversion, and urban expansion. The international trade in wild-caught Tylototriton species for the pet trade also poses a significant threat to wild populations. Population monitoring and habitat protection in Sichuan are priorities for conservation of this species.
