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.

red kangaroo

The largest kangaroo and largest marsupial on Earth, red kangaroos can stand 2 meters tall and weigh 90 kg, inhabiting the arid and semi-arid regions of inland Australia. Highly adapted to harsh desert conditions, they can survive without drinking water for long periods by extracting moisture from vegetation. Powerful hind legs enable 9-meter leaps and speeds up to 70 km/h. Males engage in ritualistic boxing contests to compete for females.
