Discovering and monitoring manta rays in the remote Conflict Islands

By collecting sightings data and photo-identification, we will be able to expand the regional database and increase our understanding of the manta rays in Papua New Guinea. Each manta has a unique pattern of spots on its ventral surface (belly) which remains largely unchanged throughout their lives. 

Much like a human fingerprint, the unique nature of these spots enables manta scientists to identify every individual manta just by photographing their ventral surfaces. This simple, non-invasive technique enables the development of photo-ID databases of all the mantas within a population, allowing us to estimate population size and document movements seasonally and spatially. Over time this detailed information can reveal migration patterns, habitats critical to feeding and reproduction, and much more - all of which is crucial if we are to make informed management decisions around the conservation of these animals.

If you have seen a manta ray anywhere in the world, you can contribute directly to the Manta Trust global research and conservation efforts.
