Cast of a real Giant Clam Shell Beautiful eye-catcher as a fruit bowl! +/- 17x41x25cm 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. The main reason that giant clams are becoming endangered is likely to be intensive exploitation by bivalve fishers. Mainly large adults are killed because they are the most profitable.
