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.

Geigenrochen

The common guitarfish, <em>Rhinobatos rhinobatos</em>, is a cartilaginous fish belonging to the order Rhinopristiformes, family Rhinobatidae. It is a member of the guitarfish group, characterized by a flattened body with a distinct guitar-like silhouette formed by the fusion of the head, pectoral fins, and trunk. <em>Rhinobatos rhinobatos</em> is assessed as Critically Endangered on the IUCN Red List, representing severe conservation concern and indicating that this species faces an extremely high risk of extinction in the wild. Pressures such as overfishing and bycatch are commonly implicated in the decline of guitarfish species globally. Detailed habitat, range, and country distribution data are not available for this species in current records. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.
