It's quite rare for a hippo to be born in captivity, but this little one — born on Sep. 7 at Planète Sauvage in Port-Saint-Père, France — is a week old and going strong! Baby hippos are born under water and weigh 60 to 110 pounds at birth. This plump cutie was born to 21-year-old mom Kara, and from now on he'll spend approximately half his life in the water. Our best wishes to mama and calf!
