African Penguin

The only penguin species native to Africa, African penguins inhabit islands and coastlines of southern Africa from Namibia to Port Elizabeth. Reaching 70 cm in height, they are recognized by their braying, donkey-like calls and distinctive black-and-white plumage with a unique pink gland above the eye. Endangered, with populations having declined by 70% since 2000 due to food scarcity from commercial fishing, oil spills, and climate-driven shifts in prey distribution.

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.
