  • In 2017, in addition to our genetics study looking at the connectivity between the Maui and Big Island mantas (which is almost complete), we will be working collaboratively with Murdoch University on a comprehensive population trend analysis to understand if our manta ray population is growing or declining and how quickly. This is a critical step for effectively managing this population.

  • Please help with your tax-deductible donation to help The Hawaii Association for Marine Education and Research (HAMER) ongoing efforts to protect its coral reefs from damaging seawalls and sediment impacts and ultimately provide a safe habitat for our majestic Maui manta rays! 


  • Meet “Slice”, an adult male manta that we see once every 4 years (2008, 2012 and November 5, 2016). Here we obtain his unique photo-identification and a size estimate using paired-laser photogrammetry (9.5 feet from wing tip to wing tip).
