CNN)Zookeepers at the Saint Louis Zoo were surprised to see their oldest snake coiled around a clutch of freshly laid eggs because she hadn't been near a male in more than 15 years.

The ball python, which has been at the zoo since 1961, laid seven eggs on July 23, Mark Wanner, the Zoological Manager of Herpetology told CNN.

"It was a surprise. We didn't expect her to drop another clutch of eggs, honestly," he said.

Keepers had noticed some changes in the snake beforehand, but Wanner said they were subtle.

The snake doesn't have a name, but is identified by the number 361003, according to the zoo. She's believed to be at least 62 years old.

Ball pythons are native to central and western Africa and can reproduce asexually, which is known as facultative parthenogenesis, the zoo said. Wanner said Komodo dragons and some other snakes and reptiles also reproduce asexually.

Females can also store sperm for delayed fertilization, but Wanner said the longest documented case they found of that happening was seven years after the contact.

She laid another clutch of eggs back in 2009, but none of those eggs hatched and there are no records of her being around a male then either.

Wanner said she could have been with a male in the late 1980s and early 1990s because keepers used to put the snakes together in buckets while cleaning their cages.

"We're saying 15 plus years, but I mean, it's probably easily closer to 30 years since she's been physically with a male," he said.

ATLANTA An Atlanta film producer has been indicted on federal charges connected to a cryptocurrency investment scheme. Hes accused of raising millions from investors and spending the money on personal items and using several others including Atlanta rapper T.I. to help promote his business.

The U.S. Attorneys office says Ryan Felton misled investors who thought they were funding an entertainment streaming platform and a new cryptocurrency.

Prosecutors say Felton instead used that money for personal use including a $1.5 million home, and a 2007 Ferrari that he paid $180,000 cash for.

Felton also posed as a potential investor using fake names on internet forums and social media to build excitement for his business and after the initial coin offering he sold thousands of coins on secondary crypto-markets to artificially inflate prices, prosecutors say.
