2002年，整个阿曼湾和波斯湾发生了水母爆发，导致手工和工业渔业的捕鱼量减少，渔具受损，海水淡化厂的运行中断，沿海发电厂的海水冷却系统受损。爆发的原因和来源以及美杜莎的种类都是未知的。本文利用伊朗渔业调查中偶然捕获的数据描述了水母的时空分布，并利用形态学和分子证据确定了水母为Crambionella orsini （Vanhoffen）。该物种是西印度洋和邻近盆地的特有物种，因此不认为物种引进是造成这种水华的原因。此外，由于藻华在地理上分布广泛，它可能不是由当地海岸退化引起的。虽然不能排除人类活动的大规模影响，但大规模的海洋或生态系统条件，也许是自然气候周期的一部分，产生适度的海面温度（就1982年以来每年的月平均异常而言）是这种特有水母繁殖的最有可能的原因。
In 2002, a jellyfish bloom occurred throughout the Gulf of Oman and the Persian Gulf causing decreased catch in artisanal and industrial fisheries, damage to fishing gear, interrupted operation of desalination plants, and damage to the seawater cooling systems Of coastal power plants. The cause and source of the bloom and the species of medusa were unknown. Here, the temporal and spatial distribution of the medusa are described using data from incidental catches in Iranian fisheries surveys, and morphological and molecular evidence are used to identify the medusa as Crambionella orsini (Vanhoffen). This species is endemic to the western Indian Ocean and adjacent basins which dismisses species introduction as the cause of this bloom. Furthermore, because the bloom was geographically widespread, it probably was not caused by local coastal degradation. Although human activities with large-scale effects cannot be ruled out, large-scale oceanographic or ecosystem conditions, perhaps part of natural climate cycles, that yielded moderate sea surface temperatures (in terms of the annual mean monthly anomaly for each year since 1982) were the most likely causes of the bloom of this endemic jellyfish.
