Some 15 years on from her critical role in one of the largest species discoveries of the past half a century, and the renowned manta ray expert Dr Andrea Marshall has done it again, officially describing a third species of the much-loved marine megafauna. Found exclusively in Atlantic Ocean waters, the Mobula yarae now joins the reef manta (Mobula alfredi) and the giant oceanic manta (Mobula birostris) as the third formally-recognised manta ray species worldwide. Published in Environmental Biology of Fishes, the new manta species discovery also represents a culmination of a 15-year scientific journey that began with observations made by the Marine Megafauna Foundation co-founder, Dr Marshall back in 2009. Dr Marshall is credited with revolutionising manta ray science by splitting what was thought to be one manta ray species into two distinct species 15 years ago. In that same landmark 2009 paper, she predicted that a third manta ray species existed in the Atlantic Ocean. Her confidence in the prediction came from years of intensive study, including countless hours spent hand drawing individual manta rays from her own underwater photographs to hone her observation skills and understand their morphology.
