Fishes associated with spinner dolphins at Fernando de Noronha Archipelago, tropical Western Atlantic: an update and overview: Fishes Checklist

An update is presented for fish species associated with spinner dolphins at Fernando de Noronha Archipelago, tropical Western Atlantic, providing a general view of their diversity. The associates are mostly reef-dwelling fishes that feed on the dolphin wastes. Twelve species are habitual or occasional plankton-eaters and two species are herbivores that occasionally forage on floating pieces of algae. One species is a strict carnivore, one species is a hitchhiker that forages on a variety of foods including parasites and dead tissue from the dolphins, and one species is a carnivore that joins the dolphin groups to forage on schools of small fishes or squids. We predict that the list of fish associated with spinner dolphins will expand mostly with addition of habitual or occasional plankton-eaters.本研究更新了西热带大西洋费尔南多·迪诺罗尼亚群岛（Fernando de Noronha Archipelago）与飞旋海豚（spinner dolphins）相关联的鱼类物种名录，全面呈现了该类群的多样性概况。这些伴生鱼类多为礁栖物种，以海豚排泄物为食。其中12个物种为经常性或偶发性浮游生物食性者，另有2个物种为草食性，偶尔会取食漂浮的藻类碎片。1个物种为专性肉食性；1个物种为随行共栖者，取食包括海豚体表寄生虫和坏死组织在内的多种食物；另有1个物种为肉食性，会跟随海豚群捕食小型鱼类或枪乌贼集群。我们预测，与飞旋海豚相关联的鱼类名录将主要通过新增经常性或偶发性浮游生物食性物种而得到扩充。
