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.
Previously considered to be the oldest known true crab, a 2010 revision concluded that Eocarcinus could not be accommodated among the Brachyura, and was instead transferred to the Anomura. [6] However, a 2020 reanalysis found that it was again the earliest known stem-group crab, but that it had not undergone the process of carcinisation. [2]

Kiwa hirsuta is a crustacean discovered in 2005 in the South Pacific Ocean. [1] This decapod, which is approximately 15 cm (5.9 in) long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). Its discoverers dubbed it the "yeti lobster" or "yeti crab". [2]
The Oldest Living Organism Is Over 2 Billion Years Old Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years.
The coconut crab (Birgus latro) is a terrestrial species of giant hermit crab, and is also known as the robber crab or palm thief. It is the largest terrestrial arthropod known, with a weight of up to 4.1 kg (9 lb). The distance from the tip of one leg to the tip of another can be as wide as 1 m (3 ft 3 in).
