Black Diamond Ray

Black Diamond is a beautiful male manta ray that Kerstin Windberg saw for the first time on June 26, 2019 at Kauna’oa Bay. . He was a pup measuring around 3 feet, and has since grown to about 7 feet.

He is not shy, but rather trusting and often comes close to the surface to feed, which brings him very close to people in the water. His claspers are visible and extend past the pelvic fins, indicating he is now almost a mature male. He is gorgeous.

Black Diamond Ray's Injuries/scarring

Black Diamond experienced several minor injuries over the years. ** On July 8th, 2023, he showed up at Kauna'oa Bay with a hook in his left cephalic fin and at least 30 feet of fishing line trailing behind him. Martina managed to cut off a good part, but not all; removing the hook completely could have caused more harm or longer-lasting injuries. Over the following years, he showed up with a little less line each time and eventually, algae even started to grow on the hook. On May 4th, 2025, the hook fell of as he was feeding at the manta viewing site - and while we were guiding a group of snorkelers to meet the mantas! When we looked at our video footage from that night, one clip showed that the hook was still attached - and by the next time he passed us, it was gone. A closer look at the footage shows the clips were taken ONE MINUTE apart. ** Black Diamond also sustained injuries in March 2025, when he showed up with long cuts down his ventral and dorsal sides, and a chunk of his right wing missing. ** Check out the image slider below!
