“…The species inventoried from rhodoliths of the Seixas Beach were recorded in other areas of Northeastern coast: in Ceará, by Martins & Martins de Queiroz (2006); in Pernambuco, by Lima & Fernandes (2009); in Alagoas, by Lima et al 2011 andMiranda et al (2012); and in Bahia, by Alves & Cerqueira (2000), Magalhães et al (2005), Manso et al (2008) and Paim et al (2015). These species also occur in the Caribbean Sea.…”

This study presents the species of echinoderms found inside rhodolith branches from Seixas Beach, State of Paraíba, Brazil, during one year of rhodolith sampling. A total of 64 specimens were analyzed and identified into 12 species, belonging to 11 genera, eight families and three classes. Brief taxonomic descriptions, figures and ecological notes for recorded species are provided. Ophiuroidea and Holothuroidea were the most representative taxa. Biogenic structures are an important habitat for young specimens and some small species of Echinodermata. Some species complete their life cycle in these structures, while others spend part of their life in these substrates and may also migrate to other habitats. The work complements the knowledge of echinoderm biodiversity from Northeastern of Brazil and aims to support future projects of protection and sustainable management of this area.

Echinodermata associados a rodolitos da Praia do Seixas, Estado da Paraíba, Nordeste do BrasilResumo: O presente estudo apresenta as espécies de equinodermos encontradas dentro de ramos de rodolitos provenientes da Praia do Seixas, Estado da Paraíba, Brasil. Um total de 64 espécimes foi analisado, sendo identificadas 12 espécies, pertencentes a 11 gêneros, oito famílias, e três classes. As amostras foram coletadas ao longo de um ano a partir de rodolitos. O artigo fornece uma breve descrição taxonômica, figuras e notas ecológicas para cada espécie. Ophiuroidea e Holothuroidea foram os grupos mais representativos. Os resultados mostram que essas estruturas biogênicas formam um habitat importante para espécies jovens e espécies pequenas de Echinodermata. Algumas espécies completam seu ciclo de vida dentro dos rodolitos, enquanto outras passam uma parte da vida nesses substratos para depois explorar em outros ambientes. O estudo complementa o conhecimento da biodiversidade de equinodermos para o nordeste do Brasil e fornece suporte para futuros projetos de proteção e uso sustentável da área.

“…Ophiocnida loveni (dd: 3.2 mm) is covered by large scales, ∼9-10 between the centrodorsal and the edge of the disc; short spinules around the disc and covering the ventral interradius; oral shields distally rounded and proximal angle acute; dorsal arm plates 1.5 times as wide as long; ventral arm plates pentagonal. The Brazilian specimens identified by Albuquerque (1986) and Paim et al (2015) were reassessed and reidentified as Ophiocnida loveni. Other specimens identified as O. filograneus in Brazil should be re-evaluated since their identifications may be based on the description by Albuquerque (1986).…”

The genera Ophiophragmus and Amphiodia are amphiurids that are considered taxonomically difficult due to their great resemblance, few diagnostic characters and synonymy problems. Our aim is to redescribe the species using scanning electron microscopy and morphometry of diagnostic structures, and to provide new information for the identification of these Ophiuroidea. Five Amphiodia spp. and six Ophiophragmus spp. recorded in Brazil were rigorously redescribed. The descriptions include new diagnostic characters derived from external morphology, arm microstructures and morphometry. We also provided comparative analyses of species with shared characters such as Amphiodia riisei and Amphiodia trychna. The geographic and bathymetric distributions of the studied species were updated, and new records are provided. All the information presented may be used in taxonomic, ecological and phylogenetic studies, helping to fill gaps in the knowledge of the biodiversity, ecology and evolution of these Ophiuroidea. Conclusively, all the tools applied here assisted in the identification of genera and species and could be useful in other taxonomic studies of Echinodermata.

“…Few Studies are available on ophiuroid association with other fauna and flora groups (Boffi, 1972;Keegan, 1974;Hendler, 1984;Hendler et al, 1995;Neira and Cantera, 2005;Girard, 2016;Lawley et al, 2018) from diverse habitats such as seaweeds, coralline algae, sponges, cnidarian and bryozoans (Mladenov and Emson, 1998;Hickman, 1998;Tahera, 2001;Mosher and Watling, 2009;Hendler and Brugneaux, 2013;Paim, 2015). Among them, the association of ophiuroid with sponges has been documented widely since the past 70 years from various parts of the world.…”

The role of brittle stars is explained in this study, concerning the interactive effects with various habitats, for resolving the relationship between community dynamics and ecosystem functions in heterogenous intertidal habitats. The study was conducted at the rocky intertidal area of Veraval (210 35'N, 690 36'E) of the Kathiawar peninsula, Gujarat, India. Habitats containing sponge, coral community, zoanthid community and coralline algae were studied to understand the key preference and role of ophiuroid in these intertidal communities.Ophiuroids act as habitat responder largely due to their being one of the most common and abundant groups. Amongst all studied ophiuroid species, Ohiactic savignyi is the only species which interacted with all selected sedentary habitats.Macrophiothrix variabilis was occasionally observed within crevices of coral colonies. A. squamata was primarily occurred with coralline algae followed by coral community. Ophiocomella sexradia was observed within the crevices of coral and zoanthid colonies. From the present study, we concluded that brittle stars mainly rely on other host organisms for their protection, food and shelter. The studied ophiuroids exhibited mutualistic and obligatory commensalism relationship with their host.
