What is the longest living animal on Earth?

The longest living animal on Earth is the ocean quahog, a type of clam that can live up to 500 years. These clams are found in the Atlantic Ocean and can reach a diameter of up to 20 centimeters.

Other animals that have a long lifespan include the bowhead whale, which can live over 200 years, and the giant tortoise, which can live up to 150 years. Some species of sharks, such as the Greenland shark, can also live for several hundred years.

Scientists are still studying the mechanisms that allow these animals to live for such long periods of time. Some of the factors that contribute to their longevity include slow metabolism, low reproductive rates, and resistance to disease and environmental stressors.

The longest living animal on Earth is the ocean quahog, a species of clam that can live for over 500 years. The oldest known ocean quahog was 507 years old when it was harvested in 2006. Ocean quahogs live in the cold waters of the North Atlantic Ocean, and their slow growth rate and long lifespan are thought to be due to the low temperatures.

Other animals that have long lifespans include the bowhead whale, which can live for over 200 years, the Greenland shark, which can live for over 300 years, and the Antarctic sponge, which can live for over 1,500 years.

The long lifespan of these animals is due to a variety of factors, including their slow metabolism, their ability to repair damage, and their resistance to disease. These factors allow them to live for many years despite the challenges of their environment.
