Presently more than 1900 species of sea stars are recognized, of which 77 are recorded for the coast of Brazil. Although the first starfish record in Brazil was published 363 years ago, our knowledge of this fauna remains unsatisfactory from a systematic and ecological point of view, particularly in the north and northeastern regions of the country. This study provides the first annotated list of sea stars from northeastern Brazil. Material described herein is housed at the collections of the Federal University of Paraíba, Federal University of Sergipe, and the Federal University of Bahia, Museum of Zoology of the University of São Paulo and Museu Nacional do Rio de Janeiro. Twenty-one species were identified, belonging to 12 genera, 10 families, and 5 orders. Descriptions of species are provided. Three new occurrences were recorded for northeast Brazil: Astropectenalligator, Luidialudwigiscotti, and Mithrodiaclavigera. Highest diversities of Asteroidea were encountered for the states of Bahia (n = 14 spp), Paraíba (n = 12 spp) and Pernambuco (n = 9 spp). No species were recorded for the states of Maranhão and Sergipe. Sandy substrates and depths below 10 m were the least sampled areas over the continental shelf. Herein we provide a first panorama on the fauna of Asteroidea occurring in the northeast region of Brazil, hopefully to function as a basic reference for biodiversity studies in this poorly studied area.
目前已识别出1900多种海星，其中77种在巴西海岸有记录。尽管巴西的首个海星记录于363年前公布，但从系统学和生态学角度来看，我们对该动物群的了解仍不尽人意，尤其是在该国北部和东北部地区。本研究提供了巴西东北部海星的首个注释清单。本文所述材料保存在帕拉伊巴联邦大学、塞尔希培联邦大学、巴伊亚联邦大学、圣保罗大学动物学博物馆和里约热内卢国家博物馆的馆藏中。共鉴定出21种，分属于12个属、10个科和5个目，并对这些物种进行了描述。记录了巴西东北部的三个新出现物种：鳄海星、路德维希海燕尾海星和棒刺米氏海星。在巴伊亚州（n = 14种）、帕拉伊巴州（n = 12种）和伯南布哥州（n = 9种）发现的海星多样性最高。马拉尼昂州和塞尔希培州未记录到任何物种。沙质底物和10米以下深度是大陆架上采样最少的区域。在此，我们提供了巴西东北部海星动物群的首个全景，希望能作为这个研究较少地区生物多样性研究的基础参考。
