Common Hippopotamus, Hippopotamus, Large Hippo

Africa's most dangerous large mammal, common hippos can reach 3,200 kg and inhabit rivers, lakes, and wetlands of sub-Saharan Africa. Semi-aquatic, spending up to 16 hours daily submerged to keep cool, they graze on land at night. Despite appearing docile, hippos are extremely aggressive and territorial, responsible for hundreds of human fatalities annually. Vulnerable, with populations threatened by habitat loss and illegal hunting for ivory tusks.

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.
