Photo 4: The life cycle of the blooming sea lily Edwardsiella carnea. a. Mature male and female polyps release gametes into the water column. b. Free-swimming planula formed after fertilization. c. The planula infects the comb host Mnemiopsis leidyi and develops into a worm-like parasitic stage. d. Planula after the parasite stage exits the comb host to the water column (e), where it can either settle on the sea floor (f) and develop into a polyp (a) or infect another comb host or a scyphozoan host such as Rhopilema nomadica or Rhizostoma pulmo (hypothetical parasite spillover) (gh) . A planula after the parasite stage may leave the scyphozoic host and move through the water column (i), where it may settle on the sea floor (f) and develop into a polyp. The dashed line represents an alternative route.

Jellyfish under attack: Researchers have found parasitic sea lilies in jellyfish for the first time
