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.

Fly Agaric

Among the most iconic and recognizable fungi on Earth, fly agaric mushrooms display striking red caps with white flecked warts across boreal forests of the Northern Hemisphere. Despite their fairy-tale appearance, they contain potent psychoactive compounds including muscimol and ibotenic acid and are moderately toxic. They form critical mycorrhizal symbioses with birch, pine, and spruce trees, exchanging mineral nutrients for carbon and playing essential roles in boreal forest nutrient cycling.
