Guitarfish Extinction
Estimated extinction time: near future.
The abundance of the medium sized coastal Brazilian guitarfish, Rhinobatos horkelii, from the southeastern coast of South America has decreased in Southern Brazil (the centre of its range) by 96% over the ten years from 1984, when its landings peaked, to 1994. It is extremely vulnerable to capture by fisheries because the inshore areas where all pregnant females and adult males congregate for parturition and mating are so heavily fished. Immature fish, which remain inshore year-round, are also taken. It is likely that this endemic guitarfish could be driven to extinction in the foreseeable future.
