The B. Nelivaru area is a gathering site for manta rays located to the northeast of B. Kunfunadhoo. Similar to the Hanifaru area, it has been observed that planktons accumulate in this region, attracting manta rays. As of 2020, 105 manta rays were detected in the area 119 times. This location is crucial for the protection of manta rays as it serves as an essential area for them to find food and for breeding. One of the most notable features of this area is the presence of a 'cleaning station' used by manta rays.
B. Atoll is globally recognized for having a large population of manta rays, emphasizing the importance of protecting such environments for manta rays. Additionally, the Nelivaru Finolhu in the area is an important environment for seabirds. It is crucial to preserve this finolhu without altering the current in this area.
