The Undulate Ray: A Hidden Gem of Bira

Among Bira's diverse marine life, the undulate ray (Raja undulata) stands out with its distinctive wavy pattern of brown and white markings, blending seamlessly into sandy substrates.


Mangga Lodge guests regularly spot undulate rays during morning dives at depths of 15–25 metres near Liukang Loe Island.
