For the starry flounder this interpretation implies that a geometric difference (between fish that are mirror images of one another) is adaptive, that left-eyedness in the Japanese starry flounder has been selected for, which provokes a perplexing question: what is the selective advantage in having both eyes on one side rather than on the other?

对于星形比目鱼来说，这种说法暗示形状上的差异（同左右两侧对称的鱼相比）是适应性的，日本的星形比目鱼之所以眼在左侧，是选择的结果，但这又引起了一个令人困惑的问题：两只眼睛都在一侧比两只眼睛分在两侧具有什么选择性的优势呢？
