声音是一种有用的线索，可以引导幼虫在岸上的方向，因为它可以在水下传播很长的距离，它也有可能传达有关源头栖息地质量和类型的有价值的信息。在这里，据我们所知，我们提供了第一个证据，证明定居阶段的沿海螃蟹物种可以解释并显示出对自然水声中栖息地相关差异的强烈定居和变态反应。实验室和野外实验表明，不同生境类型产生的不同水下声音特征对常见海岸蟹定居期幼虫的变态时间有不同的影响。与其他生境类型相比，5种温带和热带蟹类在最佳定居生境类型的声音环境下，其大翅类的蜕变时间明显缩短。这些结果表明，来自特定水下栖息地的声音可能在决定沿海螃蟹物种招募的空间模式中起主要作用。
While sound is a useful cue for guiding the onshore orientation of larvae because it travels long distances underwater, it also has the potential to convey valuable information about the quality and type of the habitat at the source. Here, we provide, to our knowledge, the first evidence that settlement-stage coastal crab species can interpret and show a strong settlement and metamorphosis response to habitat-related differences in natural underwater sound. Laboratory- and field-based experiments demonstrated that time to metamorphosis in the settlement-stage larvae of common coastal crab species varied in response to different underwater sound signatures produced by different habitat types. The megalopae of five species of both temperate and tropical crabs showed a significant decrease in time to metamorphosis, when exposed to sound from their optimal settlement habitat type compared with other habitat types. These results indicate that sounds emanating from specific underwater habitats may play a major role in determining spatial patterns of recruitment in coastal crab species.
