The red sea urchin Strongylocentrotus franciscanus is a long-lived species and may live in excess of 100 years based on tagging studies in the field and corroboration from radiocarbon analyses as reported in the literature. Size-specific survival estimates reported here show no change in annual survival probability across the 6 largest 0.5 cm size classes from 14.6 to 18.1cm. In addition to no change in survival probability there is no reduction in reproductive capacity with size. Red sea urchins show no evidence of senescence and so do not fit well within the context of the disposable soma theory of the evolution of longevity.
红海胆（Strongylocentrotus franciscanus）是一种长寿物种，根据野外标记研究以及文献中报道的放射性碳分析结果证实，其寿命可能超过100年。此处报告的特定大小的生存估计表明，在14.6至18.1厘米的6个最大的0.5厘米大小等级中，年生存概率没有变化。除了生存概率没有变化外，生殖能力也不会随着体型的增大而降低。红海胆没有衰老的迹象，因此不太符合寿命进化的一次性体细胞理论。
