A baby pygmy hippo, classified as endangered in the wild, has made his first splash on display at Melbourne Zoo under the watchful eye of his mum, Petre.
The three-week-old calf has been named Obi by keepers, which means "heart" in Igob, a local Nigerian language.
Obi has grown quickly from his birth weight of around five kg, gaining roughly 500g a day and now weighs over 13kg.
He has also been expanding his horizons by leaning to swim in the nursery yard pool.
Wild Sea Manager Justin Valentine said "he loves the water and spends hours in the small pool, so he is ready for the next step".
His mum Petre has been an excellent and attentive mother, helping him with his swimming and ensuring he never strays too far.
The pygmy hippopotamus is native to the forests and swamps of west Africa
