Happy Hippo Day!. World Hippo Day

All eyes are on hippopotamuses today! The third-largest land mammals—after elephants and white rhinos—deserve our attention, especially on World Hippo Day. Categorised as a vulnerable species by the International Union for Conservation of Nature, these semiaquatic animals are native to Sub-Saharan Africa.

This peeping calf in today's image is still under the watchful eye of its mother and will continue to be so until nursing ends at about eight months. The chubby mammals, with an impressive weight of up to 1,500 kilograms, might seem cute, but their strong jaws, large teeth and aggressive behaviour make them one of the world's most dangerous wild animals. So, admire them from a safe distance—despite their short legs, they are also fast runners!
