Such an amazing experience/rescue! Diving in the Philippines April 2014 with Manta Rays. One approached us with fishing line slicing right through her wing. Our guide spent several attempts to cut her free and finally removed the barnacle encrusted fishing line.
She swam with us for over 10minutes until we were low on air & had to leave. We watched while on our safety stop as she continued to circle below us with another Manta ray. I am convinced she stayed with us for help as this was the longest & closest interaction during the week of diving. Cudos to our guide ‘GL’! A truly amazing & emotional experience.
