New Manta Ray Species Discovered in the atlantic Ocean: Mobula yarae
A previously unkown species of manta ray, Mobula yarae, has been officially identified in the western Atlantic Ocean. The revelation, published in the journal Environmental Biology of Fishes on July 23, 2025, is crucial for targeted conservation efforts.
The name Yarae is derived from “Yara,” a mermaid-like spirit in Brazilian mythology. These manta rays are distinguished by unique markings: V-shaped white spots on their shoulders, brighter coloration around the mouth and eyes, and dark spots on their underside.
While Mobula yarae can grow to a considerable size,with a wingspan reaching 4.5 to 6 meters, many scientists have previously observed Atlantic manta rays appearing smaller. The species inhabits coastal,tropical,and subtropical waters stretching from the eastern United States to Brazil,encompassing the Gulf of Mexico and the Caribbean Sea.
The identification of M.yarae stems from a long-held suspicion by researcher Dr. Marshall, who, while describing the reef manta ray species in 2009, theorized the existence of a third Atlantic species. years of meticulous observation followed, documenting variations in color, patterns, size, habitat, and behaviour across different manta ray populations.
A pivotal moment arrived in 2017 with the discovery of a deceased young female manta ray in Florida. Genetic testing confirmed it belonged to the new species. Jessica Pate, of the Marine Megafauna Foundation and Florida Manta Project, emphasized the blessed circumstance of the find, as cartilage-based creatures typically decompose rapidly on the seabed, making testing arduous. The analysis definitively established Mobula yarae as a distinct species.
This discovery provides a valuable possibility to study the evolution and needs of this previously unrecognized animal. The species faces significant threats in its coastal habitat, including collisions with boats, entanglement in fishing gear, and accidental capture by fishermen.
“we cannot protect what we have not officially identified,” Pate stated. “Now that we’ve proven the existence of this Atlantic manta ray, we can refine our conservation research and initiatives to specifically protect it.”
Despite Dr. Marshall suffering a brain aneurysm and stroke in early 2024, requiring long-term leave, his colleagues continued the research. The formal description of M.yarae was ultimately completed by an international team led by Brazilian researcher Nayara Bucair from São Paulo University.
Researchers are now focused on learning more about Mobula yarae, including monitoring its population in the Mexican region and understanding its habitat requirements and movement patterns, notably in areas with high boat traffic and coastal development.
