Jonathan, a Seychelles giant tortoise living on the island of Saint Helena, is reported to be at least 191 years old, hence the oldest currently living terrestrial animal. If Adwaita's claim is not true, Jonathan might be the oldest known terrestrial animal to have ever existed. [108] Jonathan in 2021.
In 2022, Jonathan's estimated age exceeded that of the tortoise that Guinness World Records had recognised as the oldest recorded ever, Tu'i Malila, who died in Tonga in 1966 at the age of 189. Adwaita , an Aldabra giant tortoise that died in 2006 in the Alipore Zoological Gardens of Kolkata , India, is believed to have lived to the age of 255 ...
Ming (c. 1498 or 1499–2006), also known as Hafrún, was an ocean quahog clam (Arctica islandica, family Arcticidae) that was dredged off the coast of Iceland in 2006 and whose age was calculated by counting annual growth lines in the shell. Ming was the oldest individual (non-clonal) animal ever discovered whose age could be precisely determined.
The U.S. National Oceanic and Atmospheric Administration announced the discovery of a sea sponge which may be one of the world’s oldest living animals. Deep-sea explorers may have spotted the ...
The Greenland shark has the longest known lifespan of all vertebrate species. [43] It is estimated that the species has a lifespan of at least 272 years, with the oldest individual estimated to be 392 ± 120 years of age. Estimates of age were made using radiocarbon dating of crystals within the lenses of their eyes. [44]
Perucetus colossus, a giant whale that lived almost 40 million years ago is now thought to be the heaviest animal that has ever lived, scientists said Wednesday.
Dating to around 558 million years ago, Dickinsonia had an oval, segmented body that measured about 5 feet (1.4 meters) long, and it lacked physical features typically associated with animals ...
The coelacanth was long considered a "living fossil" because scientists thought it was the sole remaining member of a taxon otherwise known only from fossils, with no close relations alive, [8] and that it evolved into roughly its current form approximately 400 million years ago. [1]
