Manta Rays

Nusa Penida, Bali, is an important habitat for reef manta rays (Mobula alfredi) and also serves as a nursery ground for this threatened species. Visitors can see manta rays year-round at locations such as Manta Point and Manta Bay, although the dry season (May–November) often provides the best visibility. Manta rays are gentle, harmless to humans, feed on plankton, and have unique spot patterns on their bellies that can be used for individual identification.
