Life cycle of hydrozoan Obelia sp.
the gonangium. Gonangium includes gonophores (budding medusa-zooids), which you can see as round shapes inside the gonangium. When ready, the medusa buds off and swims away, as you can see in the bottom picture. Obelia's medusa was the most remarkable animal I have seen so far in this embryology class. I just wish to see its embryos someday.
