Taxonomic guide and historical review of starfishes in northeastern Brazil (Echinodermata, Asteroidea).

Gondim AI, Christoffersen ML, Pereira Dias TL - Zookeys (2014)

Bottom Line: 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.

ABSTRACT
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.

Mentions: The region has a great diversity of littoral environments, such as beaches, dunes, cliffs, estuaries, deltas, sandbanks, reefs and underwater biotopes, such as rhodolith beds, seagrass beds and coral habitats (Fig. 2). They share Tertiary sediments from the Barreiras Formation, beach rocks, and coral reefs (Suguio 2003). This coastal diversity, allied to the favorable climatic conditions and year-round warm waters, makes this region one of the most important tourist destinations in the country (Pinheiro et al. 2008).
