Porcupine Ray (Urogymnus asperrimus): The strange-looking Porcupine Ray is not a resident of the Maldives but is a frequent visitor. Covered with plate-like tenticles and sharp thorns, it is also known as the Roughskin Stingaree, Rough-skinned Ray, Solander’s Ray and Thorny Ray. The Porcupine Ray has an oval-shaped disc that can be up to a metre in disc width. Its dark-tipped tail with its dark tip lacks stinging spines and skin folds. The Ray's colour is whitish-grey to brown above and white below. This one was photographed in the lagoon of Biyadhoo Atoll.
