All About Animals

Pygmy Hippopotamus Family

  • Hip Hip Hooray!

    Born in October, 2020, "little" Ptolemy is the first pygmy hippo born at Zoo New England. You can see him on exhibit, playing and running alongside mom, Cleopatra, and making waves with little laps in his on-exhibit pool.
  • Fun Fact:

    You can often find our hippos in the water first thing in the morning.

  • Calling all Hippo Helpers!

    You can help endangered species like the pygmy hippo! It's as easy as being more mindful of your choices when you shop. Help protect hippo habitat by purchasing products that use certified sustainable palm oil instead. Look for logos like these!

  • Fun Fact:

    Our hippos are international travelers! Cleo is Canadian, and Inocencio came from Chile. Baby Ptolemy is a Boston boy, born here at Franklin Park Zoo!

  • Fun Fact: 

    Pygmy hippos mark their trails by wagging their tails as they poop. 

Pygmy hippos, Cleopatra, Inocencio and Ptolemy, are in the Tropical Forest at Franklin Park Zoo.

They are both international animals, with Cleo coming to Boston from Toronto and Inocencio coming from Chile.  You can often see one of them in water just as the Zoo opens in the morning.

Class: Mammalia 
Order: Cetartiodactyla 
Family: Hippopotamidae  
Genus: Choeropsis
Species: liberiensis

The pygmy hippo is a stout animal with a relatively small and rounded head and thick blackish skin. Like the larger Nile hippo, it excretes reddish droplets that soften and protect its skin. This creature is solitary and secretive in the wild. It's not vicious, but can be dangerous when disturbed. The pygmy hippo will attempt to intimidate potential enemies by opening its jaws and baring its canine teeth.
