在 Arctica islandica Linné 的瓣膜和铰链板的横截面上可见的内部生长带每年都会沉积，可能是对繁殖周期的反应。从条带推断出的生长速度和寿命令人惊讶：A. islandica 生长非常缓慢并且寿命很高。拥有超过90条带的人并不少见；迄今为止发现的条带数量最多为 149 个。根据中大西洋湾标本的平均大小，最众年龄估计为 65 至 105 年。
Internal growth bands visible in cross-sections of the valves and hinge plates of Arctica islandica Linné are deposited annually, possibly in response to the reproductive cycle. Growth rate and longevity, inferred from the bands, are surprising: A. islandica grows very slowly and lives to an advanced age. Individuals with more than 90 bands are not uncommon; the maximum number of bands discovered so far is 149. On the basis of average size for Middle Atlantic Bight specimens, modal age is estimated to range from 65 to 105 years.
