The otolith was used to investigate the variability between Aphanopus carbo and Aphanopus intermedius inhabiting the north-eastern Atlantic Ocean. The results indicate a high degree of morphological affinity between species and areas; a noticeable metabolic change in the otolith shape was noted in the specimens of A. carbo, which may be related to migrations of individuals from shallow water (closer to the continental coast) to deeper water (archipelagos of Madeira and the Canary Islands). The results suggest a single population for both species in the north-eastern Atlantic Ocean, although not conclusively.
耳石被用来研究栖息在东北大西洋的 Aphanopus carbo 和 Aphanopus intermedius 之间的变异性。结果表明，物种和地区之间具有高度的形态相似性；在 A. carbo 的标本中，耳石形状发生了明显的代谢变化，这可能与个体从浅水区（靠近大陆海岸）迁移到深水区（马德拉群岛和加那利群岛的群岛）有关。结果表明，东北大西洋的这两个物种属于单一种群，但这并不是结论性的。
