Habitat & Geographic Range

Coelacanth

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 8 distinct biome types spanning the Australasia and Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Comoros, Indonesia, Mozambique, and South Africa. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Polar bear

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coelacanth

A living fossil thought extinct for 65 million years until rediscovered off South Africa in 1938, coelacanths can reach 2 meters and 90 kg. They belong to an ancient lobe-finned lineage more closely related to tetrapods than to ray-finned fish, making them scientifically invaluable for understanding vertebrate evolution. Found in deep rocky reef habitats of the Indian Ocean, they are nocturnal and undergo internal fertilization, giving birth to fully formed live young. Critically Endangered.

Polar bear

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
