Abstract The Mamanguape River estuary represents an important environment for marine species, where there are the combination of softbottoms and reefs zones. The present study reports on the echinoderm species inhabiting Barra de Mamanguape, at Northeast coast of Brazil. A total of 83 specimens were analyzed, belonging to 13 species, 10 families and the classes Crinoidea, Ophiuroidea, Echinoidea and Holothuroidea. The Ophiuroidea was the most representative with seven species. The crinoid Tropiometra carinata (Lamarck, 1816) and the ophiuroid Ophiophragmus luetkeni (Ljungman, 1872) were new records for Paraíba coast. Concise taxonomic descriptions, figures and ecological notes for recorded species were provided. Comparisons between young and adult specimens of Ophioderma appressa (Say, 1825) were included. This brings information about the arrangement of species in the ecosystem, besides contributes to fill knowledge gaps about echinoderms from Northeast coast. Keywords Echinoderms . Marine biodiversity . Taxonomy . Brazilian coast . South Atlantic
Introduction The data generated by inventories compose one of the most important tools to make decisions about conservation and sustainability of natural areas. They allow understanding longterm and broad-scale changes in the composition and distribution of the fauna (Green et al. 2009). According to Amaral and Jablonsky (2005), regional phenomena can define climatic and oceanographic conditions that determine the distinctive

features of biodiversity. The coastal reef environments of the Northeast of Brazil are among the most threatened ecosystems due to the several interferences resulting from human pressures (Leão et al. 2003). The increase in human population in the coastal zone and the growth of the tourism affect ecosystem health and its functions, mainly in estuaries and surrounding areas (Barbier et al. 2011; Mérigot et al. 2017). Therefore, inventories are relevant since that bring biodiversity information f
