The giant clam (Tridacna gigas) is generally considered to be the largest bivalve mollusc. It is indeed the heaviest species, growing to over 200 kg (440 lb) and measuring up to 120 cm (47 in) in length, [2] but Kuphus polythalamius holds the record for the largest bivalve by length. A specimen owned by Victor Dan in the United States has a ...
The Registry of World Record Size Shells is a conchological work listing the largest (and in some cases smallest) verified shell specimens of various marine molluscan taxa.A successor to the earlier World Size Records of Robert J. L. Wagner and R. Tucker Abbott, it has been published on a semi-regular basis since 1997, changing ownership and publisher a number of times.
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 maxima clam has the largest geographical distribution among giant clam species; it may be found off high- or low-elevation islands, in lagoons or fringing reefs. [7] Its rapid growth rate is likely due to its ability to cultivate algae in its body tissue. [6]: 10 Although larval clams are planktonic, they become sessile in adulthood. [8]
The world's largest coral has been discovered by a National Geographic expedition to the Solomon Islands. World's largest coral found 'hiding in plain sight' near Solomon Islands for 300 years ...
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]
