In the Collection of Acanthocardia tuberculata are located specimens from many different countries. The whole Collection counts on more than 700 samples; however, here it starts with specimens of 53+ mm and it ends up with giants of 70+ mm; it currently holds both world records (WRS - World Record Size Shell) for the biggest specimen and the biggest albino specimen, a former WRS, plus a large number of the biggest specimens known in the world. It's important to precise that only an exam of the mollusk's tissues can reveal if a specimen is a true albino. So here when you read the word "albino" is just referred to samples with a full "white shell" or a "white shell" that have few colored spots.
