Ylistrum balloti, known as Ballot's saucer scallop is found around the waters of Australia.

This scallop may live for a maximum of four years, and reach 14 cm in shell length, though more commonly 8 to 9 cm.

Well regarded as seafood in Asia and Australia.

[1][2][3] The Ballot's saucer scallop is highly available throughout the Australian coast.

[6] A recent report confirmed from Borneo island (Sarawak, Malaysia) suggested the range is expanding to the north.
