Like reef-building corals, this hydrozoan is susceptible to bleaching, caused by higher-than-normal water temperatures. During bleaching events, corals lose the algal symbionts (zooxanthellae) which they need to survive.
Globally, coral reefs are rapidly degrading from the combined effects of climate change, overfishing, pollution, and habitat destruction. These issues require multidisciplinary solutions that include ecological, social, and economic perspectives. Around the world, marine scientists, policy makers, social scientists, and coastal communities are working together to ensure futures for these ecosystems and the people that rely on them.
