Range

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

Tiger

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 6 distinct biome types spanning the Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Colombia and Ecuador. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

Tiger

The largest wild cat on Earth, tigers can exceed 300 kg and inhabit forests from the Russian Far East to Southeast Asia. Solitary ambush predators with distinctive orange and black striped coats that provide camouflage in dappled light. Critically endangered, with fewer than 4,000 remaining in the wild due to poaching and deforestation.
