The oldest recorded specimen was 179 years old, but individuals usually live up to 140 years.

I didn't expect them to have such long lifespans

Bivalves can get very, very old. The shells hold growth information like tree rings so age data can get pretty accurate.

The oldest noncolonial animal is believed to be the arctic quahog, which has been confirmed to live 507 years! Older ones are almost surely out there now!
