For those seeking more unusual encounters, the region is home to the peculiar wobbegong shark, often found camouflaged on the seabed, and the walking shark, a unique species that uses its fins to ‘walk’ along the bottom. Manta Point and Arborek Jetty are consistently excellent locations for observing these creatures.

For a luxury Raja Ampat cruise October 2027, the chances of significant manta ray aggregations are very high, offering unforgettable photographic opportunities.
