1996年10月，在加利福尼亚州中部海拔230米的蒙特利潜艇峡谷中发现了一只水仙。水母是使用遥控运载器(ROV)Ventana从RV Point Lobos查看和收集的。这种原位观察的优点包括能够识别标本铃声上的寄生虫(看起来像小的、不透明的圆圈)。在实验室中，这些圆形物体被发现是寄生在表皮内的类似蛇类的幼虫，这些幼虫的触须可以自由移动、伸展和收缩。目前尚不清楚这些幼虫是不是真正的寄生虫--即从宿主水母那里吸取营养的另一个物种的幼虫，或者他们是否是被孵化的后代。水母是蒙特利湾最多的水母属之一，这是加州洋流系统中首次报道该属的寄生虫。
A narcomedusa, Solmissus incisa , was collected off central California in the Monterey Submarine Canyon at 230 m in October 1996. The medusa was viewed and collected from the RV Point Lobos using the remotely operated vehicle (ROV) Ventana. Advantages of such in situ observation include the ability to recognize parasites (which appear as small, opaque circles) on the bell of the specimen. In the laboratory, the circular objects were found to be parasitic, cnidarian-like juveniles developing within the epidermis, stages that moved freely, extending and retracting their tentacles. It is not known whether these juveniles are true parasites - i.e. juveniles of another species drawing nutrition from the host medusa, or whether they are offspring being brooded. Solmissus is one of the most numerous genera of medusae in Monterey Bay, and this is the first report of parasites on members of that genus in the California Current system
