Chola guitarfish

The White-spotted Guitarfish (Rhinobatos albomaculatus) is a cartilaginous elasmobranch in the family Rhinobatidae, belonging to the guitarfishes — a group with a flattened, elongated body combining features of both rays and sharks. The species is distinguished by white spots on the dorsal surface, which give it its scientific epithet albomaculatus. It inhabits shallow coastal and estuarine waters of the tropical and subtropical western Atlantic and possibly the eastern Pacific, where it forages over sandy and muddy bottoms for small crustaceans, molluscs, worms, and fish. Like other rhinobatids, it reproduces viviparously, producing small litters of pups after a prolonged gestation period. The IUCN classifies Rhinobatos albomaculatus as Critically Endangered — one of the highest threat categories — reflecting severe population declines resulting from intensive bycatch in artisanal and commercial trawl fisheries across its restricted coastal range. Guitar rays globally are facing a conservation crisis; many species of Rhinobatidae have experienced rapid declines of 80% or more over recent decades in heavily fished coastal waters. The shallow, near-shore habitats they occupy offer no refuge from demersal fishing gears, and their low reproductive rate means recovery from depletion is extremely slow even if fishing pressure is reduced.
