Happy, an Asian elephant at the Bronx Zoo whose life offered researchers profound insights into animal behavior and became central to a landmark animal rights case, has been euthanized at the age of 55, the zoo announced Wednesday.
The elephant was put to sleep on Tuesday after nearly five decades at the facility. Zoo officials stated that several age-related conditions had rapidly worsened in recent weeks, with Happy exhibiting signs of declining kidney or liver function. A subsequent necropsy revealed severe arthritis and large, inoperable uterine tumors, conditions that are notoriously difficult to diagnose in elephants through standard examinations or imaging.
