摘要短脊虾（Alpheus brevicristatus De哈安，1844）是日本最常见的滩涂虾类之一。该物种有时与兼性共生的虾虎鱼（Acentrogobius spp.）相伴。本文对A.日本高知县宇之内湾潮滩的短柱藻。我们还回顾了现有的文献alpheid洞穴形态使用树脂铸造技术，以确定洞穴的存在和不存在的虾虎鱼的变化。九个洞穴被铸造在原位使用聚酯树脂。所有洞穴都长，但结构浅，有几个漏斗状开口和短的死囊分支。该物种似乎使用几个洞穴开口进入沉积物表面以高效率进食。虾虎鱼并不与所有的洞穴有关;然而，1-3只小的Alpheid虾Athanas Kubo，1936年被埋葬在7个洞穴中。回顾12项研究的洞穴形态的16个种的树脂铸造技术的基础上显示了广泛的变化，洞穴特征，如洞穴深度，长度和开口的数量。我们的研究结果表明，洞穴结构的影响，物种特异性特征和沉积物类型。讨论了共生虾虎鱼的存在对虾洞形态的影响。
The Alpheus brevicristatus De Haan, 1844 is one of the commonest shrimp species inhabiting the tidal flats in Japan. This species is sometimes accompanied by the facultative symbiotic goby, Acentrogobius spp. Here, we investigated the burrow morphology of A. brevicristatus in a tidal flat of Uranouchi Inlet, Kochi Prefecture, Japan. We also reviewed existing literature on alpheid burrow morphology using the resin casting technique, to determine how burrows vary in the presence and absence of gobies. Nine burrows were casted in situ using polyester resin. All burrows were long, but shallow in structure, with several funnel-shaped openings and short cul-de-sac branches. This species appears to use several burrow openings to access the sediment surface for feeding with high efficiency. Gobies were not associated with all burrows cast; however, 1–3 individuals of the small alpheid shrimp Athanas japonicus Kubo, 1936 were entombed in seven of the casts. A review of 12 studies on the burrow morphology of 16 Alpheus species based on resin casting techniques showed wide variation in burrow characteristics, such as burrow depth, length, and number of openings. Our findings suggest that burrow structure is influenced by species-specific characteristics and sediment type. The possibility that the presence of the symbiotic goby affects the burrow morphology of Alpheus shrimp is discussed.
