Pictures of baby animals generally make everyone happy, but that's not what grabbed my attention. Zoom in on the image as much as you can and check out the texture, particularly in the mother's skin. I wonder if hippos are soft, or if they are rough like an elephant?

Five week old hippopotamus calf nicknamed 'Muddy' (L) stands close to her mother Primrose (R) in her enclosure at the Werribee Open Range Zoo, in Melbourne on May 6, 2008. The gestation period for the hippo is between 7.5 and 8 months, and the birth is the result of the introduction that Keepers arranged last winter between Primrose and Harry.
