Wildlife Rescuers on Instagram: "Mars is a baby pygmy hippo born on June 26, 2025, at Tanganyika Wildlife Park to parents Pluto and Posie. He weighed just 14 pounds at birth and is already growing fast, now around 30 pounds. Named through a public vote to match his dad’s planetary theme, Mars is one of fewer than 450 pygmy hippos in human care worldwide. He’s quickly become a fan favorite thanks to his playful zoomies, naps, and silly pool-time moments with his mom. Video credit goes to @tangany
