- Maximum longevity
- 106 years (wild)

- Sample size
- Data quality
These animals have been found to live up to 106.0 years .
This species exhibits an accumulation of fluorescent age pigments. This accumulation happens at a faster rate in the first two years of life, but it stops entirely between the ages of 2 and 4. Age related decrease in HSP60 expression and in catalase activity has been also observed. Furthermore, older clams have been shown to have higher levels of expression of HSP70 and lower levels of expression of HSP90 .
