Jonathan (hatched c. 1832) [2] [3] is a Seychelles giant tortoise (Aldabrachelys gigantea hololissa), a subspecies of the Aldabra giant tortoise (Aldabrachelys gigantea).His approximate age is estimated to be 192 as of 2024, making him the oldest known living land animal.
It is therefore one of the oldest known sea turtles. but a new fossil named Desmatochelys padillai in 2015 is estimated to be as old as 120 million years. [2] While the specimen showed many characteristics of modern sea turtles, it differed from the typical sea turtle body plan in several ways.
Debby, the polar bear, an inhabitant of the Assiniboine Park Zoo in Winnipeg, Canada, was the oldest polar bear and third-oldest bear species on record when she died in 2008, at the age of 42. [133] The oldest recorded bat, a Siberian bat [134] (previously identified as a Brandt's bat), was at least 41 years old at the time of capture. [135]
Esmeralda is an Aldabra giant tortoise living in the Galapagos Islands. [6] There is a report that a tortoise was kept in the garrison by French explorer Chevalier Marc-Joseph Marion du Fresne. The creature lived in the fort for 118 years. It died in 1918 when it became blind and accidentally fell to its death from atop a gun turret.
As of 2022, Jonathan, a Seychelles giant tortoise, is thought to be the oldest living giant tortoise at the age of 192 years. [25] Esmeralda, an Aldabra giant tortoise, is second at the age of 180 years, since the death of Harriet, a Galapagos giant tortoise, at 175. An Aldabra giant tortoise living on Changuu off Zanzibar is reportedly 198 ...
Desmatochelys was a large sea turtle, with some specimens reaching up to 2 meters long. [4] Members of the genus are characterized by the extended skull roof, large nasal bones, and a paddle-like humerus, as well as a distinct body shell or carapace and reduced plastron like other protostegids. [19]
Tortoises are the longest-living land animals in the world, although the longest-living species of tortoise is a matter of debate. Galápagos tortoises are noted to live over 150 years, but an Aldabra giant tortoise named Adwaita may have lived an estimated 255 years. In general, most tortoise species can live 80–150 years.
At the time of his death in 2006, Adwaita was believed to be amongst the longest-living animals in the world. He may have been from Aldabra, an atoll in the Seychelles. This anecdotal report has not been confirmed. [4] The animal was one of four tortoises that lived at Robert Clive's estate at Barrackpore, in the northern suburbs of Calcutta. [5]
