Echinodermata das praias de Salvador (Bahia, Brasil) The Echinoderms of Salvador beaches (Bahia, Brazil)
<abstract language="eng">This paper presents 28 species of Echinoderms collected on 5 beaches of Salvador (12Âș54' to 13Âș01' S and 38Âș26' to 38Âș33' W), Brazil, which are distributed in 19 families. Ophiuroidea represented 53,6% of the collected species, followed by Echinoidea (28,6%), Asteroidea (7,1%), Holothuroidea (7,1%), and Crinoidea (3,6%). Ophiuroidea and Echinoidea were the most frequent groups, occurring at all the studied beaches while Crinoidea occurred only on 20% of them. Most of the species are characterized as belonging to the tropical warm waters, some to the shallow coastal areas and some having a broad bathymetric distribution. The richness of species values on beaches ranged from 7 to 24, at Itapua Beach, and from 2 to 14 among different kinds of habitats, where protected ones showed higher values
