Abstract
ABSTRACT Species of extant nautiluses (in Nautilus and Allonautilus) have been anecdotally described as opportunistic scavengers. Here, we examine foraging and scavenging behaviors of Nautilus in field and laboratory settings. Given that nautiluses are nektobenthic, solitary animals living in resource-limited habitats, we predict that odor is the predominant cue used to locate prey. Here, we show that nautiluses display a stereotyped set of search postures in the wild. In field and laboratory trials, nautiluses displayed the same stereotyped foraging postures, suggesting it is a natural and functional reflex in nautilus, and can be replicated under controlled conditions. A series of foraging behaviors induced by olfaction is a highly desirable trait to scavenge for food in the deep-sea. Considering the recent conservation initiatives and regulations now in place to protect declining nautilus populations, understanding and describing feeding behaviors and the ecology of nautiluses are a critical component to support conservation efforts.
期刊介绍:
Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation.
As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above.
The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis.
With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
