Ming was the oldest individual (non-clonal) animal ever discovered whose age could be precisely determined. [1] [2] [3] Thought to be 405 years old, Ming was later determined to be 507 years old, although the clam had previously been killed to make this determination. The size of the clam was 87 mm × 73 mm (3.4 in × 2.9 in).
The shell of the clam ranges from 15 centimetres (6 in) to over 20 centimetres (8 in) in length, but the extremely long siphons make the clam itself much longer than this: the "shaft" or siphons alone can be 1 metre (3 ft 3 in) in length. The geoduck is the largest burrowing clam in the world. [3]
This slow life style results in exceptional longevity, e.g., with a reported age, for Ming the clam, of 507 years. It is the longest lived non-colonial metazoan species with an authenticated lifespan. [4] [7] [8] It is unknown how long it could have lived had it not been collected alive by a 2006 expedition.
Scientists have identified the oldest living species on Earth is a deep sea organism that hasn't evolved in more than two billion years. And, it may prove Charles Darwin's Theory of Evolution ...
Ctenophores are one of, if not the, oldest animals on Earth — quite possibly a sister to all other animals in the tree of life, so “they provide a really unique opportunity to study ...
Mantle of giant clam with light-sensitive spots, which detect danger and cause the clam to close. Tridacna gigas, the giant clam, is the best-known species of the giant clam genus Tridacna. Giant clams are the largest living bivalve molluscs. Several other species of "giant clam" in the genus Tridacna are often misidentified as Tridacna gigas.
Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates. [1]The earliest known life forms on Earth may be as old as 4.1 billion years (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia.

A new record for smallest dino eggs ever discovered. The most complete egg, which also happens to be the smallest, measures about 29 millimeters (about 1.14 inches), according to China University ...
