🐟Common stingray
蓝纹魟（學名：Dasyatis pastinaca）是魟科魟属的鱼类，分布于大西洋东北部、地中海和黑海。该鱼一般栖息于水深不超过60米的沙质或泥质海床上，常将自己掩埋于沉积物中。该鱼胸鳍宽大，尾部呈鞭状，上下均有褶皱，体宽约45厘米。该鱼体表一般为纯色，皮肤光滑，仅在背部正中有一排棘刺。 蓝纹魟一般以底栖甲壳类为食，但亦会捕食软体动物、蠕虫和小型硬骨鱼。该鱼为卵胎生物种，胚胎会先后通过卵黄和母体子宫腺所分泌的液体获取营养。雌性蓝纹魟一年怀孕两次，每次孕期约4个月。其一胎有4—9条幼鱼，一般会在浅水区生产。蓝纹魟的毒刺蜇伤可使人痛苦万分，但通常不致命。即便如此，欧洲古典时代的学者对其威力多夸大其词。虽鲜少有针对蓝纹魟的商业捕鱼，但该鱼常出现于兼捕中。捕获的蓝纹魟可食用，亦可提取鱼肝油或制成鱼食。目前，蓝纹魟种群有明显下降趋势，IUCN将其评为易危。
