First Friday: Sex on the Coral Reef

Using gorgeous images, marine biologist Erika Woolsey will provide an inside look at coral reef ecosystems, including the rare and exotic mass spawning event that keeps divers and scientists traveling each year to Australia's Great Barrier Reef to witness.

Part of the Mill Valley Library's after-hours First Friday series, this event is free and open to adults and high school students only. Space is limited, so registration is recommended.
