A review of the primary literature on the cartilaginous fishes (sharks, skates, rays and chimaeras), together with new information suggests that 106 species occur in Chilean waters, comprising 58 sharks, 30 skates, 13 rays and five chimaeras. The presence of 93 species was confirmed, although 30 species were encountered rarely, through validated catch records and sightings made in artisanal and commercial fisheries and on specific research cruises. Overall, only 63 species appear to have a range distribution that normally includes Chilean waters. Actual reliable records of occurrence are lacking for 13 species. Chile has a cartilaginous fish fauna that is relatively impoverished compared with the global species inventory, but conservative compared with countries in South America with warm-temperate waters. The region of highest species richness occurs in the mid-Chilean latitudes of c. 30-40° S. This region represents a transition zone with a mix of species related to both the warm-temperate Peruvian province to the north and cold-temperate Magellan province to the south. This study provides clarification of species occurrence and the functional biodiversity of Chile's cartilaginous fish fauna.
对软骨鱼类（鲨鱼、鳐鱼、魟鱼和银鲛）的原始文献进行回顾，并结合新信息表明，智利海域有106种软骨鱼类，包括58种鲨鱼、30种鳐鱼、13种魟鱼和5种银鲛。通过手工和商业渔业以及特定研究航行中的有效渔获记录和目击情况，确认了93种的存在，尽管有30种很少被发现。总体而言，似乎只有63种的分布范围通常包括智利海域。13种缺乏实际可靠的出现记录。与全球物种清单相比，智利的软骨鱼类区系相对贫乏，但与南美洲有暖温带水域的国家相比则较为保守。物种丰富度最高的地区出现在智利南纬约30 - 40°的中纬度地区。该地区代表了一个过渡地带，有来自北部暖温带秘鲁省和南部寒温带麦哲伦省的混合物种。这项研究澄清了智利软骨鱼类区系的物种出现情况和功能生物多样性。
