The oceanic cephalopod fauna of the Arabian Sea has not been well studied. The Hawaiian flying squid Nototodarus hawaiiensis (Oegopsida: Ommastrephidae) is known to have a very broad, disjunct distribution in tropical to subtropical waters. In the present study, the squid Nototodarus hawaiiensis is reported for the first time from the Arabian Sea. Five females ranging in size from 62 to 128 mm dorsal mantle length (DML) were collected. Age estimates based on the statolith-increment analysis ranged from 79 to 132 days, with growth rates ranging from 0.78 to 0.99 (mean = 0.93) mm DML/day. Back-calculated hatch dates occurred from November to January. Stomach-content analysis revealed that the dominant prey was crustaceans.

阿拉伯海中的夏威夷飞乌贼 Nototodarus hawaiiensis(头足纲:Ommastrephidae):范围扩展、年龄和生长
阿拉伯海的海洋头足类动物群尚未得到很好的研究。众所周知,夏威夷飞乌贼Nototodarus hawaiiensis(Oegopsida:Ommastrephidae)在热带到亚热带水域中具有非常广泛的间断分布。在本研究中,首次报道了来自阿拉伯海的鱿鱼Nototodarus hawaiiensis 。收集了五只体型从 62 到 128 毫米背披风长度 (DML) 不等的雌性。基于静石增量分析的年龄估计范围为 79 至 132 天,增长率范围为 0.78 至 0.99(平均值 = 0.93)mm DML/天。回溯计算的孵化日期为 11 月至 1 月。胃内容物分析表明,主要猎物是甲壳类动物。
