摘要

在沙滩上10平方米的区域内发现了100多只最近死亡和垂死的标本。海滩剖面显示，数百具先前死亡的水仙外骨骼被冲上岸，埋在沙子和枯萎的海草中。造成水蛭大量死亡的病原尚未被发现。然而，对波浪接近海岸的观察表明，可能的证据表明，这可能是由于强烈的近岸波浪和洋流的结合。这一观察结果提出了一个重要的研究关注，以调查的病因为物种保护。

Mass mortality of regular sea urchin Salmacis virgulata L. Agassiz and Desor, 1846 at Dhanushkodi, Southeast coast of Tamil Nadu, Gulf of Mannar, India

More than 100 numbers of recently dead and dying specimens were found within a 10 m 2 area on the sandy beach. Beach profiles indicated several hundreds of exoskeletons of previously dead S. virgulata were washed ashore and buried in sand and withering seagrass. The causative agent responsible for mass mortality of S. virgulata is yet to be discovered. However, observations on wave approach toward shore indicated possible evidence that it could be due to a combination of strong nearshore waves and currents. This observation raises a critical research concern to investigate etiology of S. virgulata for species conservation.

期刊介绍： Started in 1972, this multi-disciplinary journal publishes full papers and short communications. The Indian Journal of Geo-Marine Sciences, issued monthly, is devoted to the publication of communications relating to various facets of research in (i) Marine sciences including marine engineering and marine pollution; (ii) Climate change & (iii) Geosciences i.e. geology, geography and geophysics. IJMS is a multidisciplinary journal in marine sciences and geosciences. Therefore, research and review papers and book reviews of general significance to marine sciences and geosciences which are written clearly and well organized will be given preference.
