You will find these medusae affixed to eelgrass or seaweeds in subtidal regions. When detached, they cannot swim and therefore move very little in a lifetime. As seen here, they posess 8 marginal lobes that end in clusters of tentacles. The sting of the cells is used to deter predators and to catch prey, mostly the caprellid amphipods abundant in eelgrass beds.
