Manta rays were observed traversing Hapuna Beach to Mauna Kea Beach, Hawaii, on three separate occasions (days) between 9am and 10am. Hypothesis: Manta rays commute near shore in a familiar route, where there are feeds they will make stops. Some may end up at Kawaihae Break wall where they congregate during surf season. At these times in the day, they appear to be resting, hence minimal proportion efforts, and gliding. At 3:59 one manta ray appears to have a hypnic jerk, or sleep jerk. (september 2017)
