Lifespan, ageing, and relevant traits
- Observations
Some bivalves show slow growth and exceptional longevities with no mortality increase in adulthood [0013]. The best example is the ocean quahog (Arctica islandica). Other bivalves may show age-related changes though [0002].
However, most marine bivalves have been shown to be short lived. Furthermore, lifespan has been shown to increase while growth rate decreases with latitude, with tropical bivalves living less than polar bivalves. Since growth rate can be used as a proxy for metabolic rate, studies have concluded that short lived bivalves have a faster metabolism than long lived bivalves [1307].
