New tracking data, spanning multiple years, describes how manta rays change their movement patterns as they mature: younger animals tend to remain close to coastal areas, while adults travel much farther, including long-range movements.
Both outlets report that tagged manta rays repeatedly return to preferred nearshore sites during early life, but adult manta rays roam over broader areas and migrate hundreds of kilometres. The accounts also point to age-related differences in ranging behaviour, based on monitoring across years including 2018 to 2025. While the overall finding is consistent—juveniles staying closer to home and adults moving more widely—the emphasis differs slightly. Business Line foregrounds the long-term tracking window and the contrast between shore fidelity in youth and wide migration in adulthood. Channel NewsAsia frames the same general pattern using the “stay close to home” versus “roam more widely” structure.
No specific location, methodology details, or study institution are provided in the supplied summaries, but both pieces agree on the age-dependent shift in manta-ray movement and the repeated use of coastal areas by younger rays.
