Satellite Tagging and Photographic Identification Reveal Connectivity Between Two UNESCO World Heritage Areas for Reef Manta Rays

A groundbreaking study reveals significant connectivity between two UNESCO World Heritage Areas, Ningaloo Coast and Shark Bay, for reef manta rays (Mobula alfredi). Using satellite tagging and a long-term photographic-identification database, researchers found that these rays can travel up to 700 km, demonstrating directional dispersal patterns. The study also showed that some individuals exhibit long-term site affinity, with the longest recorded residency spanning 15.16 years. This research highlights the importance of marine parks in protecting critical habitats for this species, providing crucial insights for conservation efforts.
