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!
I'm not quite sure what makes Pygmy Hippopotamuses so cute — their small size or seriously squinty expressions. Take Kambiri, for example, she's giving the camera the stink eye like the man behind it is about to steal her leaf . . . that's also bigger than her head. Don't worry, lil girl, all eyes are on you, not the foliage!
Born in Sydney's Taronga Zoo — also the home to that superstar pygmy hippo named Monifa in 2008 — Kambiri is the first babe being raised by her birth mama in over 20 years!

Have any idea how to clean these big mouths with ginormous chompers? Look and see how it's done on this willing (not-so-willing?) model named Orien.
Just weeks after we first met that lil pygmy pachy, a new hippo babe steals the scene! Check out Kumba, a (standard-sized) hippopotamus who entered the world on Oct. 11 at 110 pounds, and learn some neat hippo trivia along the way!
Mmm, that baby looks juicy. I mean that lettuce — lettuce equals juicy, baby hippos equal cuddly. My bad. Peep new pics of the lil one from the Rotterdam Zoo and start the show.
If you haven't yet ooohed and ahhed over this baby hippo, the newborn from the Netherlands is actually a Pygmy (like Monifa), which is different than the standard-sized Nile hippopotamuses. Obviously the Pygmy hippos are much smaller (and rarer), but exactly how much smaller and rarer? Find out when you take this quiz!
I spy lettuce, carrots, and cucumber chunks for this baby hippo and proud mama. Did you know that hippos eat just about 1 percent of their total body weight as adults? Don't call them greedy, though — if necessary, the huge mammals can store two days' worth of grass in their tummies and go up to three weeks without eating.
There's a whole buffet laid out here and no need to gorge, so check out one more picture of the grazing babe when you read more
Well hello there, Leishan! The newest pygmy hippo was welcomed to the world last month at the Edinburgh Zoo, and boy he sure is cute! Pygmy hippos are an endangered species, so if I were a matchmaker, I'd have to pair this little guy up with the media darling, Monifa! It's a match made in zoo heaven. But besides being an endangered species, do you know any other facts about hippos? There's a lot to discover, so get crackin'!

I guess I've never seen a hippo that close up to compare, but look how hairy the face is! This happy family lives in Hamburg, Germany – the babies, born in November and January, were the first to join the zoo in a number of years. 
OK, so maybe I don't know if they're hungry but they certainly seem thirsty and to love playing in water . . . see pictures below for evidence of splashiness.
Although it isn't Monifa (who's currently a close second in our cutest zoo baby of '08 poll), this equally adoro hippo is having some watery fun with mama, Kati, at the Berlin Zoo! Born less than a month ago on Nov. 29, it makes sense that the yet-unnamed babe can already swim since many hippopotamuses are born underwater with the mom pushing the lil one to the surface to breathe, and even nursing while in there.
