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.
This is the largest extant snail (shelled gastropod) species in the world, and arguably the largest (heaviest) gastropod in the world. Although the shell itself is quite well known to shell collectors because of its extraordinary size, little is known about the ecology and behavior of the species, [7] except for one study about its feeding habits.
The largest known T. gigas specimen measured 137 centimetres (4 ft 6 in), and it weighed 230 kg (510 lb) dead and was estimated to be 250 kg (550 lb) alive. It was discovered around 1817 on the north western coast of Sumatra, Indonesia, and its shells are now on display in a museum in Northern Ireland. [6]: 31 [15]
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]
The Solomon Islands have the world’s second-highest coral diversity, with more than 490 species of hard and soft corals.The world is currently experiencing a fourth global coral bleaching event ...
The largest known specimen of Triplofusus giganteus had a shell 604.8 millimetres (23.81 in) long. [6] However, populations have declined in size in recent years due to overharvesting; the largest individuals observed in various recent surveys have had shells ranging from 341 to 400 millimetres (13.4 to 15.7 in).
The cache, which is believed to be the largest of its kind ever found in Israel, contains coins written in both Aramaic and Greek. Archaeologists Uncover One Of The World's Oldest Christian Churches
This is three times the size of the largest fish eyes—up to 90 mm (3.5 in) in swordfish—and more than twice the diameter of the largest whale eyes—up to 109 mm (4.3 in), 61 mm (2.4 in), and 55 mm (2.2 in) in blue, humpback, and sperm whales, respectively—which are the largest among vertebrates. [5]
