This work presents the structural and functional traits of benthic amphipods in the Saudi waters of the Arabian Gulf. Sixty-two species belonging to 37 genera and 17 families were recorded. Sensitive species such as Grandidierella bonnieroides, G. exilis, Gammaropsis atlantica and Caprellidea indet., were mostly dominant. The average values of richness, density and diversity (H' log) were 11 ± 1, 512 ± 232 ind. m-2 and 3.1 ± 0.1 respectively. The density decreased with increased in depth (nearshore (NS) - 784 ± 445 and offshore (OS) - 222 ± 28, p = 0.023), while evenness (NS - 0.93 and OS -0.94) and diversity (NS - 3.10 and OS - 3.18) were unaffected by depth. Interstitial space dwellers (56.76%) and surface deposit feeders (60.16%) were dominant in the nearshore sand substratum. However, domicolous (72.2%) with suspension and surface deposit feeders (71.7%) were more in offshore silt sediments. The combination of depth, pH and TPH (p = 0.249) influenced the distribution of amphipods.
这项研究展示了阿拉伯湾沙特海域底栖双壳纲动物的结构和功能特征。记录了属于17科37属的62个物种。诸如博氏大颚细蚤、纤细大颚细蚤、大西洋长腹钩虾及未确定的麦杆虫科等敏感物种占主导地位。丰富度、密度和多样性（H'对数）的平均值分别为11±1、512±232个/平方米和3.1±0.1。密度随深度增加而降低（近岸（NS）- 784±445，离岸（OS）- 222±28，p = 0.023），而均匀度（NS - 0.93，OS - 0.94）和多样性（NS - 3.10，OS - 3.18）不受深度影响。间隙空间栖息者（56.76%）和表面沉积物摄食者（60.16%）在近岸砂质底层中占主导。然而，在离岸淤泥沉积物中，穴居者（72.2%）以及悬浮物和表面沉积物摄食者（71.7%）更多。深度、pH值和总石油烃（TPH）的组合（p = 0.249）影响了双壳纲动物的分布。
