Turtles can live long lives. The oldest living turtle and land animal is said to be a [[Seychelles giant tortoise]] named [[Jonathan (tortoise)|Jonathan]], who turned 187 in 2019.<ref>{{cite web |url=https://www.guinnessworldrecords.com/news/2019/2/introducing-jonathan-the-worlds-oldest-animal-on-land-561882 |title=Introducing Jonathan, the World's Oldest Animal on Land at 187 Years Old |last=Millward |first=Adam |publisher=[[Guinness World Records]] |date=February 27, 2019 |access-date=July 14, 2020 |archive-date=August 9, 2020 |archive-url=https://web.archive.org/web/20200809153110/https://www.guinnessworldrecords.com/news/2019/2/introducing-jonathan-the-worlds-oldest-animal-on-land-561882 |url-status=live }}</ref> A [[Galápagos tortoise]] named [[Harriet (tortoise)|Harriet]] was collected by [[Charles Darwin]] in 1835; it died in 2006, having lived for at least 176 years.
