A hippo looks cute emerging from the water with greenery on its head, before shaking it off and letting out a ferocious growl in the Masai Mara, Kenya in the last decade of January 2024. Hippos, who can weigh up to 1,800kg, are responsible for 500 human deaths every year, and are the third largest land mammal in the world behind the elephant and the rhino.
