Porites coral colonies at Olaikuda reef, Palk Bay region were observed with pink spot and covered with mucus. Close examination of these spots revealed the presence of polychaete tubeworm and vermitid snail. The polychaete worm made aberrant growth with pink spot and this would change the growth pattern or morphology of coral colonies. In addition to that, mucus produced by vermetid snail stressed the corals in the Palk Bay region by covering the corals with their sediment trapped mucus. This is the first report of stresses imposed by coral associates on coral colonies from the Indian waters. The presence of tube dwelling vermetid snail, the stressor factors could be an indication to understand the health status of coral reefs.

管居腹足动物是印度东南海岸帕克湾地区热带珊瑚礁珊瑚礁状况的指标

观察到 Palk Bay 地区 Olaikuda 礁的 Porites 珊瑚群落有粉红色斑点并覆盖有粘液。仔细检查这些斑点，发现存在多毛类管虫和蚯蚓。多毛类蠕虫异常生长并带有粉红色斑点，这将改变珊瑚群落的生长模式或形态。除此之外，蚯蚓产生的粘液通过用沉积物捕获的粘液覆盖珊瑚来压迫Palk Bay地区的珊瑚。这是关于珊瑚同伙对印度水域珊瑚群落施加压力的第一份报告。管栖蜗牛的存在，压力因素可能是了解珊瑚礁健康状况的指标。
