许多海虾共生地生活在其他无脊椎动物的体表或体内，而其他海虾则使用其他动物的洞穴。在生态学的背景下，囊虾的洞穴共生研究很少，可能是因为这种关系的神秘的动物区系性质很难观察到。有限的知识模式的洞穴使用alpheid虾留下了一个空白，在我们的理解他们的进化历史。本文描述并比较了在同一寄主横谷乌骨鸡的洞穴中共生的两种扁头鱼Stenalpheopsanacanthus和Athanasanderus的行为。我们发现，这两个alpheid物种使用U。在水族箱中，横谷蚁的洞穴，但它们的洞穴使用模式是很不同的。S的平均时间。anacanthus的首次入洞时间比A.（13 min）.随后，S。短刺蚁对洞穴的利用时间较长（占观察期的80%）。49%）。尾先出的频率，这可能表明一个突然驱逐出洞穴的主机，在A。比S.全棘（7%）。这种差异可以归因于共生关系的性质，在S。anacanthus，但在A. - 是的由于其共生生活方式的多样性，对穴栖共生扁蚜的生态学和进化生物学研究具有很大的潜力。
Many alpheid shrimps live symbiotically on the body surface or inside the bodies of other invertebrates, while others use burrows made by other animals. The burrow symbiosis of alpheid shrimps is poorly studied in the context of ecology, probably because the cryptic infaunal nature of the relationship is hard to observe. The limited knowledge of the pattern of burrow use by alpheid shrimps leaves a gap in our understanding of their evolutionary history. We described and compared the behavior of Stenalpheops anacanthus and Athanas japonicus, two alpheid species living symbiotically in the burrows of the same host, Upogebia yokoyai. We found that both alpheid species used U. yokoyai burrows in aquaria, but their burrow use patterns were quite different. The average time taken for S. anacanthus to enter the burrow for the first time was much shorter (1 min) than that of A. japonicus (13 min). Subsequently, S. anacanthus made longer use of the burrow (80% of the observation period) than A. japonicus (49%). The tail-first exit frequency, which may indicate a sudden expulsion from the burrow by the host, was more frequent in A. japonicus (25%) than in S. anacanthus (7%). Such differences could be attributed to the nature of the symbiotic relationship, obligate in S. anacanthus but facultative in A. japonicus. Because of the diversity of symbiotic lifestyles, there is considerable potential to study the ecology and evolutionary biology of burrow-symbiotic alpheids further.
