First Record of a Color Variation of Cuthona Diversicolor (Tergipedidae: Aeolidina) Feeding on the Hydroid, Aglaophenia Cupressina, on a North Sulawesi (Indonesia) Coral Reef

Coral reefs in the Bunaken Marine Park, North Sulawesi, Indonesia are already well known as hotspots of biodiversity. Bunaken was declared a national park in 1991, based on its high coral, mangrove, and fish diversity, and the abundance of rare species. This area is characterized by fringing reefs on Bunaken I. and mainly by wide bays of volcanic sand and patch reefs along the Manado Coast. Patch reefs located in the sandy and shallow lagoons, often ignored by divers, show a very high biodiversity and several undescribed associations between different organisms.
