Big Snap Daddy, widely regarded as one of the largest common snapping turtles on record, has died in Nebraska after a rapid decline in health, state officials confirmed. He was estimated to be nearly 100 years old.

The turtle lived at the Schramm Education Center in Gretna, Nebraska, where he served as an educational ambassador animal for decades. According to the Nebraska Game and Parks Commission, he was humanely euthanized on Monday after his condition worsened significantly over the weekend. No additional medical details were released.

When last weighed in March, Big Snap Daddy registered 102 pounds, far exceeding the typical adult male common snapping turtle, which generally weighs around 35 pounds in the wild.

The turtle was first placed on public display in the early 1990s after being caught in the Missouri River near Peru, Nebraska. Officials said an angler originally intended to keep the animal for consumption but ultimately donated it due to its unusually large size.

At the time of donation, the turtle weighed about 47 pounds and was transferred to the educational facility, where it remained on exhibit for more than 30 years.

Experts estimated Big Snap Daddy’s age to be between 96 and 100 years based on his size, shell condition, and physical wear. Nebraska herpetologist Dennis Ferraro previously noted that his longevity was exceptional even for his species.

The Nebraska Game and Parks Commission said the animal made a lasting impact on visitors and staff who cared for him over the years, describing him as a memorable presence at the education center.

Common snapping turtles are widely distributed across North America, ranging from the southern United States into parts of Canada. While adults have few natural predators, wildlife officials note they remain vulnerable to human-related threats throughout their lifespan.
