摘要基于葡萄牙阿拉比达海洋公园的潜水调查，研究了齿齿叉尾轮鱼对微生境的利用模式。在所有考察的微生境中，该物种仅在藻类草坪、海胆和巨石中发现。本文首次分析了齿海胆与海胆的关系。对微生境有不同的利用，小的幼鱼进入藻类草坪，与海胆一起发现的中间个体，以及主要出现在巨石中的较大的鱼。并对深度分布规律进行了分析。
SynopsisThe patterns of microhabitat utilization by the clingfish Apletodon dentatus were investigated, based on SCUBA diving surveys at the Arrabida Marine Park (Portugal). In all inspected microhabitats, this species was only found in algal turfs, sea urchins and boulders. The association of A. dentatus with sea urchins is here analysed for the first time. There was a differential utilization of the microhabitats, with small juveniles recruiting to algal turfs, intermediate individuals found in association with the sea urchins Paracentrotus lividus and Sphaerechinus granularis and larger fish occurring mainly in boulders. The depth distribution patterns are also analysed.
