Spiny butterfly ray

The Spiny butterfly ray (Gymnura altavela) is characterized by its dark brown to olive or even grayish color on top with a paler underside. This species is native to the eastern Atlantic, ranging from the British Isles to South Africa, and extends its habitat into the Mediterranean Sea and parts of the Black Sea. Gymnura altavela has a distinctive appearance, featuring a broad, flat disk shape with a short tail, lacking the typical long stinger found in many other rays. This species is not commonly known in the aquarium hobby, primarily due to its size and habitat preferences, making it less accessible and practical for personal aquarium enthusiasts.
