Smooth butterfly ray

The Smooth butterfly ray (Gymnura micrura) is a species of ray characterized by its broad, flat body and smooth skin, devoid of dermal denticles. It typically displays a brown or olive coloration on its dorsal surface, blending into the sandy or muddy seabeds of its habitat. This ray is native to the western Atlantic Ocean, ranging from New Jersey, USA, to Brazil, including parts of the Gulf of Mexico and Caribbean Sea. The pectoral fins of this species are greatly enlarged, giving it a distinctly rounded or diamond-shaped appearance. The Smooth butterfly ray is not commonly known in the aquarium hobby, primarily due to its size and the specialized care it requires.
