Bumpy is a species of
jellyfish, "Stellamedusa ventana".
The species was first described in the "Journal of the Marine Biological Association" in
2004by Kevin Raskoff and George Matsumoto of the Monterey Bay Aquarium Research Institute. As of February 2004, seven specimens have been observed, five off the Californiacoast in Monterey Bayand two in the Gulf of California. Unlike most medusae, they lack marginal tentacles. Specimens so far found reach almost 10cm in diameter, which is large for a scyphomedusa. The bell is blue-white in colour. The exumbrella is white, and this and the four oral arms are covered with large nematocyst-laden projections filled with stinging cells, enabling the jelly to capture food items of a variety of sizes; it seems to prefer large prey, up to half its size, which is unusual in jellies that capture prey with their bells rather than with tentacles. The bumpy appearance that the stinging cells give to the jelly led to its common name. The species name comes from the remotely operated vehicle ( ROV) "Ventana", a deep-diving robot submarinethat first recorded the jelly on video in 1990.
"Stellamedusa ventana" has so far been observed only at mesopelagic depths, i.e. between 150 and 550 meters. At these depths, sunlight does not penetrate, but there is still a reasonable amount of oxygen. Many species of jellyfishes live at this level, and it is likely that "S. ventana" feeds primarily on other jellies. Another large jellyfish discovered by the same researchers is Big Red.
