Meet one of the animal kingdom's most enchanting yet overlooked creatures: the pygmy hippopotamus. While its much larger cousin, the common hippo, tends to hog the spotlight, this reclusive forest-dweller offers a fascinating window into the biodiversity of West Africa's rainforests.
Shy, nocturnal, and rarely seen in the wild, pygmy hippos are a favorite subject for conservationists and wildlife lovers alike. Here's what makes them so unique.
Pygmy hippos are much smaller than common hippos, typically weighing 397 to 606 pounds (180 to 275 kg) and measuring about 5 to 6 feet long.
They stand roughly 2.5 to 3.3 feet tall at the shoulder, less than half the height of a common hippo.
Pygmy hippos are native to the dense forests and swamps of West Africa, with the largest population found in Liberia and smaller populations in Sierra Leone, Guinea, and Ivory Coast.
Unlike common hippos, which live in large social groups, pygmy hippos are solitary except when mating or when a mother is raising her calf.
They are primarily nocturnal, spending most daylight hours hidden in dense vegetation and becoming active to feed at night.
Pygmy hippos are herbivores, feeding on ferns, broad-leaved plants, grasses, and fallen fruit found in the forest.
By eating fruit and dispersing the seeds through their droppings, pygmy hippos help support plant growth throughout their forest habitat.
Gestation lasts about 6 to 7 months, and a mother usually gives birth to a single calf, which can follow her within days of birth.
The pygmy hippopotamus is classified as Endangered by the IUCN, with an estimated 2,000 to 2,499 mature individuals left in the wild.
Habitat loss from logging and agriculture, along with hunting for meat, are the biggest threats to their survival.
Their skin secretes a pinkish fluid, sometimes called 'blood sweat,' that acts as a natural sunscreen and antiseptic, even though it is neither blood nor sweat.
In captivity, pygmy hippos can live 30 to 55 years, though wild lifespans are believed to be considerably shorter and are not well documented.
Despite their small size, pygmy hippos are strong swimmers with nostrils and ears that close automatically underwater.
Pygmy hippos are so elusive and hard to study in the wild that much of what scientists know comes from captive populations in zoos.
The pygmy hippopotamus is one of only two living species in the family Hippopotamidae, the other being the common hippo.
