在海洋和陆地四足动物中都有使用四肢觅食的记录。人们曾经认为，由于适应流体环境中运动的身体计划的物理限制，这些行为在海洋四足动物中不太可能出现。尽管存在这些障碍，但之前已经报道过九个海洋四足动物科在觅食时使用十种不同类型的肢体。在这里，我们扩展了海龟记录的肢体使用类型，并将其与目前已知使用肢体觅食的海洋四足动物的多样性放在一起。此外，我们认为这种行为可能发生在海龟祖先身上，因此，海洋四足动物肢体使用行为的进化时间线可能会延长到大约 7000 万年前。通过直接现场观察和众包，我们记录了不同栖息地和猎物类型的行为范围，表明其广泛存在。我们认为海洋四足动物中这些行为的存在可能受到肢体活动性和进化历史的限制，而不是觅食生态或社会学习。这些行为也可能是由于半水生生活史而得以保留的祖先前肢使用的残余。
The use of limbs for foraging is documented in both marine and terrestrial tetrapods. These behaviors were once believed to be less likely in marine tetrapods due to the physical constraints of body plans adapted to locomotion in a fluid environment. Despite these obstacles, ten distinct types of limb-use while foraging have been previously reported in nine marine tetrapod families. Here, we expand the types of limb-use documented in marine turtles and put it in context with the diversity of marine tetrapods currently known to use limbs for foraging. Additionally, we suggest that such behaviors could have occurred in ancestral turtles, and thus, possibly extend the evolutionary timeline of limb-use behavior in marine tetrapods back approximately 70 million years. Through direct observation in situ and crowd-sourcing, we document the range of behaviors across habitats and prey types, suggesting its widespread occurrence. We argue the presence of these behaviors among marine tetrapods may be limited by limb mobility and evolutionary history, rather than foraging ecology or social learning. These behaviors may also be remnant of ancestral forelimb-use that have been maintained due to a semi-aquatic life history.
