While morphological abnormalities have been widely reported in batomorphs, ontogenetic deformities of the posterior pectoral fin are rare. In this paper, we present a bluespotted ribbontail ray, (Forsskål, 1775), with symmetrically deformed posterior pectoral fins. The specimen was observed through aerial imagery on a coastal sandflat in the central Red Sea (22.30° N, 39.09° E). The bilateral symmetry of the deformity indicates it likely has a genetic base. However, lacking access to the specimen, the ultimate cause of the abnormality remains uncertain. The incomplete disk closure did not seem to affect survival, as the specimen reached a disk width of 22 cm, well above the regional size at sexual maturity. Our observations constitute both the first report of a morphological abnormality in and the first record of a batomorph with a symmetrically deformed posterior pectoral fin.

虽然在鳐形目动物中广泛报道了形态异常，但胸鳍后部的个体发育畸形却很罕见。在本文中，我们展示了一条蓝点魟（Taeniura lymma，(福斯科尔，1775)），其胸鳍后部对称变形。该标本是通过航拍图像在红海中部的沿海滩涂（北纬22.30°，东经39.09°）观察到的。畸形的双侧对称性表明其可能有遗传基础。然而，由于无法获取该标本，异常的最终原因仍不确定。不完全的圆盘闭合似乎并未影响生存，因为该标本达到了22厘米的圆盘宽度，远高于该区域的性成熟大小。我们的观察既是关于蓝点魟形态异常的首次报告，也是具有对称变形胸鳍后部的鳐形目动物的首次记录。在本文中，我们展示了一条蓝点魟（Taeniura lymma，(福斯科尔，1775)），其胸鳍后部对称变形。该标本是通过航拍图像在红海中部的沿海滩涂（北纬22.30°，东经39.09°）观察到的。我们的观察既是关于蓝点魟形态异常的首次报告，也是具有对称变形胸鳍后部的鳐形目动物的首次记录。
