Two Cape Porcupines, brothers Walter and Winni, arrived at Adelaide Zoo on Thursday, May 2, after being transferred from Monarto Safari Park.Born in August 2023, the young porcupines are the first of their species to call Adelaide Zoo home, the zoo said in a press release sent to Storyful.“This was the first time the young porcupines have moved habitats so it was a big day of new sounds and experiences, but Walter and Winni were very calm throughout the trip," the zoo’s senior keeper, Elise Maurer, said.Cape Porcupines are the largest porcupine species globally.Walter and Winni, who are eight months old, currently tip the scales at about 12kg. However, they’re still growing and are expected to reach their full size of 27kg, the zoo said. Credit: Adelaide Zoo via Storyful
