Marine mammals are exceptionally significant animals with innumerable essential ecological roles in global aquatic ecosystems while the evolutionary divergence was taken place from the terrestrial habits. The adaptive radiation in aquatic life endorses various structural modifications in their general organization of body plan. Short-finned Pilot Whales (Globicephala macrorhynchus Gray, 1846) are predominantly distributed mostly in tropical and temperate regions of the world’s oceans as one of the greatest social organisms which travel in higher speed in a group only with several individuals. Such practice of their social life is the prime risk for their population depletion as mass stranding across the world due to natural or anthropogenic threats while stranding of a single individual is a rare occurrence for this species and resulted mostly due to disease. During the present study, a stranded skeletal system (incomplete) of Short-finned Pilot Whale containing 49 parts (1 skull, 1 lower mandible, 3 ribs, 37 vertebrae, 1 scapula, 2 humeri, 2 radii, and 2 ulnae) were found at South Reef Island of Andaman and Nicobar Islands. Detailed cranial measurements were taken. Condylobasal length is 56.6 cm. This is the first stranding report of a solitary individual of Short-finned Pilot Whale in Andaman and Nicobar Islands.

海洋哺乳动物是异常重要的动物，在全球水生生态系统中扮演着无数重要的生态角色，而进化的分歧是从陆地习性中发生的。水生生物中的适应性辐射支持其身体计划的一般组织中的各种结构修改。短鳍领航鲸 ( Globicephala macrorhynchus)Gray, 1846) 主要分布在世界海洋的热带和温带地区，是最大的社会生物之一，它们在只有几个人的群体中以更高的速度旅行。由于自然或人为威胁在世界范围内大规模搁浅，而单个个体的搁浅对于该物种来说是罕见的，并且主要是由于疾病造成的，因此这种社会生活实践是其人口枯竭的主要风险。在本研究中，发现了短鳍领航鲸的搁浅骨骼系统（不完整），包含 49 个部分（1 个头骨、1 个下颌骨、3 根肋骨、37 根椎骨、1 块肩胛骨、2 根肱骨、2 根桡骨和 2 根尺骨）在安达曼和尼科巴群岛的南礁岛。进行了详细的颅骨测量。髁基底长 56.6 厘米。
