摘要

辐射状牙齿在与食物相互作用时必须应对磨损。在一些软体动物类群中,磨损应对机制与铁或硅的高含量结合有关,这在以前已经确定。而对于大多数物种,特别是那些没有加入此类成分的辐射体的物种,其磨损机制还未得到充分研究。在本研究中,我们记录并描述了模式物种 Loligo vulgaris(头足纲)的辐射齿磨损情况。通过应用一系列方法,我们描述了牙齿的基本成分和机械性能,以深入了解应对磨损的机制。研究发现,易磨损的牙齿区域硬度更高、更硬。此外,与摄食物相互作用的表面有一层含硅量较高的薄涂层,这可能会减少磨损。本文提供的数据可作为系统研究辐射磨损的范例,以了解辐射牙齿的结构与其特性之间的关系。

Wear patterns of radular teeth in Loligo vulgaris (Cephalopoda; Mollusca) are related to their structure and mechanical properties

Radular teeth have to cope with wear, when interacting with ingesta. In some molluscan taxa, wear-coping mechanisms, related to the incorporation of high contents of iron or silica, have been previously determined. For most species, particularly for those which possess radulae without such incorporations, wear-coping mechanisms are understudied. In the present study, we documented and characterized the wear on radular teeth in the model species Loligo vulgaris (Cephalopoda). By applying a range of methods, the elementary composition and mechanical properties of the teeth were described, to gain insight into mechanisms for coping with abrasion. It was found that the tooth regions that are prone to wear are harder and stiffer. Additionally, the surfaces interacting with the ingesta possessed a thin coating with high contents of silicon, probably reducing abrasion. The here presented data may serve as an example of systematic study of radular wear, in order to understand the relationship between the structure of radular teeth and their properties.

期刊介绍: Each Interface Focus themed issue is devoted to a particular subject at the interface of the physical and life sciences. Formed of high-quality articles, they aim to facilitate cross-disciplinary research across this traditional divide by acting as a forum accessible to all. Topics may be newly emerging areas of research or dynamic aspects of more established fields. Organisers of each Interface Focus are strongly encouraged to contextualise the journal within their chosen subject.
