Welcome to our blog.


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! 

Mahalo!

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).
