The 3 longest living animals

Ocean Quahog (Arctica islandica): The ocean quahog, a type of clam, holds the record for one of the longest-lived animals on Earth. Some individuals have been documented to live for over 500 years. In 2006, scientists discovered a specimen that was estimated to be around 507 years old.

Greenland Shark (Somniosus microcephalus): These large, slow-moving sharks found in the cold waters of the North Atlantic and Arctic Oceans can live for centuries. Some Greenland sharks have been estimated to be more than 400 years old, making them one of the longest-lived vertebrates on Earth.

Aldabra Giant Tortoise (Aldabrachelys gigantea): These giant tortoises are native to the Aldabra Atoll in the Seychelles. They have a remarkable lifespan and can live for well over 100 years. In captivity, some have been known to reach ages exceeding 200 years. The famous tortoise Adwaita, who lived in the Alipore Zoological Gardens in India, was believed to have been around 250 years old when he passed away in 2006.
