Hippos are the third largest mammal on the planet, behind only the elephant and the white rhino. But there is a variety of hippo known as the pygmy hippo that is tiny by comparison, especially when it is very young. And that makes the animal a natural curiosity. Witness the popularity of Moo Deng, a pygmy hippo who lives in a Thailand zoo and became a viral sensation in 2024.

The editors of LIFE shared the fascination.

The magazine’s June 2, 1941 issue included a story headlined “World’s Smallest Hippopotamus Arrives in U.S. From Liberia.” The pygmy hippo in question had been abandoned by its mother, found by Liberian natives and turned over to a man named Silas E. Johnson, who worked in Liberia and was an amateur zoologist.

Johnson then sailed to New York City for his “biannual three-month vacation in the U.S,” according to LIFE, and brought the baby hippo with him. When the hippo arrived in America, he was two months old, weighed nine pounds, was 18 inches long, and had acquired the name Skipper during the course of his sea journey. Legendary LIFE staff photographer Alfred Eisenstaedt was there to capture the magic.

LIFE explained exactly what made Skipper so precious:

The rarity of Mr. Johnson’s pet lies in the fact that pygmy hippopotamuses, found only in Liberia, are stalwart fighters which fiercely protect their young….When he is full-grown, Skipper will weight about 400 pounds. Normal hippos weight 30 pounds at birth, three tons at maturity.

While Skipper was rare, he was not entirely unique. In 1952 LIFE featured another pygmy hippo that had come to the U.S. This little fellow was named Gumdrop, and he and his zookeeper were photographed for the magazine by George Skadding. Unlike Skipper, Gumdrop came to the U.S. in the company of his mother.

How rare is a pygmy hippopotamus? Outside of zoos, the animal’s primary habitat remains in Libera and other neighboring West African countries. According to an estimate in 2015, only about 2,500 pygmy hippos remain alive in the wild.
