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.
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 creature in the video is a Pacific razor clam, though it looks enough like a geoduck to befuddle even a knowledgeable biologist: Digging into wet sand is a survival technique for the critter ...
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]

HONG KONG — For at least three centuries, it grew in secret on the seabed of the southwestern Pacific Ocean. Now, the largest coral ever recorded has been discovered, scientists said Thursday ...
By day, the clams spread out their mantle so that the algae receive the sunlight they need to photosynthesize, whereas the colour pigments protect the clam against excessive light and UV radiation. Adult clams can get most (70–100%) of their nutrients from the algae and the rest from filter feeding. [12] When disturbed, the clam closes its shell.
