"#Corals remain healthier and recover faster if they are surrounded by #fish that eat different types of #seaweed, such as #parrotfish, #surgeonfish and #rabbitfish. #SeaCucumbers also are important reef partners. They feed on #bacteria and other organic materials in ocean sediments, cleaning up the area around #CoralReefs."

The world’s fourth mass coral bleaching is underway, but well-connected reefs may have a better chance to recover

Coral reefs share genetic material across wide areas, with help from ocean currents. This ability is especially important during episodes like the mass bleaching currently occurring.
