In the Mediterranean there is a meadow of sea grass thought to be over 100,000 years old. In the White Mountains of California, there stands a Great Basin Bristlecone Pine that researchers estimate is 5,063 years old. But plants aren't the only organisms that know how to grow old. Here are nineteen Methuselahs of the animal kingdom.

Ming (1499-2006), an ocean quahog clam, dredged alive from the bottom of the North Atlantic near Iceland in 2006 with 200 others, and put in a freezer (it's a common practice) to take them to the United Kingdom's Bangor University.

First the researchers thought it was 405 years old, but after a reanalysis in 2013 it turns out that it was more than hundred years older.

The oldest bowhead whale was 211 years old at the time of its death in the 1990s.

The age of these animals were measured in a really interesting way, according to Alaska Science Forum:

George sent Bada 48 frozen bowhead eyeballs, each about the size of a billiard ball, he and other biologists had saved from whale hunts in Barrow, Gambell, Wainwright, Point Hope, and Savoonga from 1978 to 1997.

Bada found that most of the adult whales were between 20 and 60 years old when they died, but five males were much older. One was 91, one was 135, one 159, one 172, and the oldest whale was 211 years old at the time of its death.

Bada explained that the method of measuring changes in aspartic acid to determine age has an accuracy range of about 16 percent, which means the 211 year-old bowhead could have been from 177 to 245 years old.

Timothy (c. 1839-2004), a Mediterranean spur-thighed tortoise, lived for 165 years. He was discovered aboard a Portuguese corsair in 1854 and served as a mascot on Navy vessels until 1892, saw the first bombardment of Sevastopol in the Crimean War from HMS Queen, and travelled to the East Indies and China, among others.

After her retirement she lived at Powderham Castle until her death in 2004. After an attempt to mate him in 1926 failed, it was established that Timothy is a female. In the last years, she had a written tag says "My name is Timothy. I am very old – please, do not pick me up."
