Eve (platypus)

Eve was hatched in October 2004 at Taronga Zoo in Sydney, Australia.^[1] In October 2019, she was transferred to the San Diego Zoo Safari Park along with a male platypus named Birrarung, whose name comes from a river in Australia.^[2] Eve's name came from Evelyn, who had been a care specialist for her in Australia.^[3] The animals were transported in custom-built crates and accompanied by a keeper to assist their acclimation.^[4]

As of December 2019, 15-year-old Eve weighed approximately 2.5 pounds (1.1 kg) and was roughly the length of a human arm from wrist to shoulder.^[1]

Within the Walkabout Australia area, the Nelson A. Millsberg Platypus Habitat housed the animals in an enclosure that replicated freshwater conditions and accommodated their nocturnal activity. Eve spent much of the day in a nest box.^[5] She was fed a diet of live prey, including crayfish, crickets, ghost shrimp, and worms, and showed a preference for smaller crayfish.^[6]

Eve died on March 18, 2026, following treatment for pneumonia.^[2][7] She was approximately 21 years old, slightly exceeding the typical lifespan of a platypus in human care.^[8][9]

When Eve and Birrarung arrived in San Diego, it was the first time in more than half a century that platypuses had been cared for outside of Australia and 60 years since a platypus had been on display in the United States.^[10][2][11]

Eve was part of a program to study platypus biology and husbandry outside Australia.^[12][13]
