海洋沉积物的间隙环境是一个由孔隙和孔隙组成的复杂网络，生活着丰富多样的动物。生活在这些间隙空间中的动物对这种环境表现出广泛的功能适应，并发展出许多在小空间中移动和导航的策略。间质环节动物表现出显著的形态多样性，其中一些具有灵巧的丝状触须（在环节动物中常见的触手状附属物）。这些触须在间隙中的功能尚未被仔细研究，我们认为它们在间隙的导航中起着感觉作用。我们研究了三科间质环节动物的长而灵巧的触须的运动功能，以确定它们在间质导航中的作用。我们观察了两种原生芦苇科（Protodrilidae），Pharyngocirrus eroticus（Saccocirridae）和protodorvillea recuperata(Dorvilleidae)，因为它们通过两种透明的沙子类似物：cyolite和玻璃珠。所有四种环节动物在运动时都使用触须探测间隙环境，并且触须探测的距离大于头部移动的距离，表明触须导航是一种感官形式。触须在间隙环境中作为感觉器官的功能提出了关于间隙导航以及没有附属物的动物如何映射周围环境的有趣问题。这种先前未记载的功能的发现只有通过直接观察间隙行为才有可能，这强调了开发新技术在更自然的栖息地研究这些动物的重要性。
The interstitial environment of marine sediments is a complex network of voids and pores that is inhabited by a diverse and abundant fauna. Animals living within these interstitial spaces show widespread functional adaptations to this environment and have developed many strategies for moving and navigating through small spaces. Interstitial annelids demonstrate a remarkable level of morphologic diversity, and some possess dexterous, filiform palps (tentacle-like appendages common across Annelida). The function(s) of these palps in interstitial spaces has not been closely examined, and we propose that they serve a sensory role in the navigation of interstitial spaces. We investigated the locomotory function of long, dexterous palps in three families of interstitial annelids to determine their role in interstitial navigation. We observed two species of protodrilids (Protodrilidae),Pharyngocirrus eroticus(Saccocirridae), andProtodorvillea recuperata(Dorvilleidae), as they moved through two transparent sand analogs: cyolite and glass beads. All four species of annelids consistently used their palps to probe the interstitial environment while locomoting, and the distance probed with their palps was greater than the distance traveled with their heads, indicating a sensory form of palp-based navigation. The functionality of palps as sensory organs in the interstitial environment raises interesting questions about interstitial navigation and how fauna without appendages map their surroundings. The discovery of this previously undocumented function was possible only through the direct observation of interstitial behavior and emphasizes the importance of developing new techniques to study these animals in more natural habitats.
