A fluorescent green flower anemone (Epicystis crucifer) releases sperm into the water column at the Coral Morphologic lab.

On May 24th we observed this fluorescent green flower anemone (Epicystis crucifer) spawning in our lab, and managed to film the event. The anemone continued to release sperm for nearly 30 minutes, while several other nearby flower anemones released significantly smaller amounts of gametes. This was the second time we have witnessed a flower anemone spawning event at our lab this spring. We first observed a synchronous spawn of more than a dozen anemones in an outdoor aquaculture system that receives natural sunlight on April 12th. After the jump are photos of anemones spawning during this event.

We are excited to share that Coral Morphologic has contributed film and images to Coral: Rekindling Venus, a full-dome digital planetarium motion picture directed by artist Lynette Wallworth. Coral: Rekindling Venus explores the magnificence of the coral reef and its organisms in a high definition, 360 degree view with a score including Antony Hegarty and Christian Fennesz. The film premieres in twenty-four (24) planetariums around the world on June 5th, which coincides with the Transit of Venus. The movie’s title equates the significance of coral reefs in the 21st century to this historic astronomical event.
