Prevention of epibiosis is of vital importance for most aquatic organisms, which can have consequences for their ability to invade new areas. Surface microtopography of the shell periostracum has been shown to have antifouling properties for mytilid mussels, and the topography shows regional differences. This article examines whether an optimal shell design exists and evaluates the degree to which shell microstructure is matched with the properties of the local fouling community. Biomimics of four mytilid species from different regional provenances were exposed at eight different sites in both northern and southern hemispheres. Tendencies of the microtopography to both inhibit and facilitate fouling were detected after 3 and 6 weeks of immersion. However, on a global scale, all microtopographies failed to prevent fouling in a consistent manner when exposed to various fouling communities and when decoupled from other shell properties. It is therefore suggested that the recently discovered chemical anti-microfouling properties of the periostracum complement the anti-macrofouling defence offered by shell microtopography.
预防生物污损对大多数水生生物至关重要，这会影响它们入侵新区域的能力。贻贝的壳表几丁质层的表面微观形貌具有抗污损特性，并且其形貌具有区域性差异。本文研究了是否存在最佳的壳设计，并评估壳微观结构与当地污损生物群落特性的匹配程度。来自不同区域起源的四种贻贝的仿生样本在南北半球的 8 个不同地点进行了暴露实验，分别在浸泡 3 周和 6 周后检测到微观形貌对污损的抑制和促进作用。然而，在全球范围内，当暴露于各种污损生物群落并与其他壳特性解耦时，所有微观形貌都未能以一致的方式防止污损。因此，建议壳几丁质层最近发现的抗微生物污损的化学特性可以补充壳微观形貌提供的抗大型污损防御。
