A new species of Ophiomisidium (Echinodermata: Ophiuroidea) from the continental shelf and slope off southern Brazil

Abstract

A new species of Ophiomisidium is described and regards about reproduction are presented. It is the ¢rst species in the genus to posses, apparently, a brooding development. Very few specimens of species of Ophiomisidium have previously been collected, but over 3000 specimens of the new species were collected on the continental shelf and slope (60^810 m depth) o¡ southern Brazil. They were obtained during the REVIZEE Programme, the ¢rst extensive surveys to examine Brazilian ophiuroids from depths greater than 200 m.

Echinoderms from Santa Catarina, southern Brazil: an update on biodiversity and distribution

“…The continental shelf of Santa Catarina was mainly explored by the ReviZEE program (Living Resources in the Exclusive Economic Zone). The program provided the discovery of new marine species for Brazil, especially those inconspicuous and difficult to be sampled, such as ophiuroids (Borges et al, 2002(Borges et al, , 2006. In this study, we observed that most of the ophiuroids registered for Santa Catarina came from the ReviZEE program (45%).…”

Annotated checklist of Echinoderms from Araçá Bay, Southeastern Brazil

“…The echinoderm fauna in Brazilian waters is composed of 340 species (Ventura et al 2013). In the state of São Paulo, southeastern Brazil, 120 echinoderm species have been reported (Hadel et al 1999;Borges et al 2006;Borges and Amaral 2007). In São Sebastião, in northeastern São Paulo state, 38 species are known (1 Crinoidea, 9 Asteroidea, 13 Ophiuroidea, 9 Echinoidea, and 6 Holothuroidea) (Netto et al 2005).…”
