This was in Bonaire which is right next to Aruba and Curacao . It ' s regularly referred to as the divers island because there are not really any traditional beaches it ' s all coral beaches but you can basically walk into the ocean and dive so no need for boats and tour guides . It would be a terrible island for a non diver and the bioluminesce isn ' t even that great there . I ' m no expert but I believe Indonesia and Australia the Pacific in general has more bioluminesce . If I remember correctly this was a semi annual known event where more of the organisms that bioluminesce were active in those waters . When we finished the dive both my sister and brother said that was nothing . they literally both meh ' d the whole thing as I went on endlessly by how astounded I was .
