The reef manta ray (Mobula alfredi) is a tough swimmer. They can travel hundreds of kilometres to feed themselves. The longest recorded movement for an individual reef manta ray was 1,150km, observed in eastern Australia.
But even though they are able to swim long distances, our study on reef manta rays in Raja Ampat, Southwest Papua, discovered they are more likely to swim short distances. They appear to prefer staying close to their local habitats, strengthening their social bonds and forming distinct populations.
Our research – involving researchers from Indonesia, New Zealand and Australia and published in the Royal Society Open Science journal in April – increases our understanding of this globally vulnerable species.
