Nusa Penida is also famous for being home to the majestic Manta Ray, and nowhere is better than Manta Point to catch a glimpse of these amazing fish. The dive site is very shallow at around 7 meters deep as this is the cleaning station for the manta ray. Mantas come here in vast numbers looking for the cleaner wrasse that live in the nearby reef to assist them by eating off the bacteria and other parasites from their skin. These manta rays can measure up to 5 meters and are Reef Mantas. They have unique black and white markings, which allow them to be easily identified, and on different days of diving, you can spot the same rays. Even though these rays are harmless, they are an endangered species and face extinction.

The bay has great water temperatures of around 24 degrees and so there are large quantities of plankton for the manta to feed on. The bay though is quite large and so can have quite strong currents. This can limit the times when diving is possible.

There is a reef as well in the bay with great soft and hard corals in great condition. They contain many moray eels, porcelain crabs and sea snakes. Common reef fish include lionfish, triggerfish, angelfish, banner fish, anemone fish, Moorish idols and angelfish. The bay features large limestone rocks and these are home to many different types of octopus.

It is also possible to spot nurse sharks, and blue spotted stingrays. There are sometimes so many blue spotted rays that they are found lying on top of each other on the bottom of the seabed. As the dive site is close to the Mola Mola cleaning stations, it is possible to see these fish as well at this site.
