Presenting the "city of gonads" jellyfish


Marilyn sez, "What lives off the coast of Australia, is shaped like transparent flying saucers, and has external gonads that resemble the skyline of a city? Give up? It's Csiromedusa medeopolis, a jellyfish that's so different from all other jellyfish that it "has forced the creation of a whole new family and genus, Csiromedusidae and Csiromedusa, respectively."

Arranged in a "crater" at the center of the jellyfish's top side, the gonads, upon close inspection, resemble "skyscrapers in a downtown business district," said Lisa-Ann Gershwin, curator of zoology at the Queen Victoria Museum and Art Gallery in Launceston, Australia.

Accordingly, Gershwin gave the jellyfish the species name "medeopolis," Latin for "city of gonads."

"It's just so completely different from anything we've ever seen before," Gershwin said.
