Prey selectivity of the octocoral Carijoa riisei at Pernambuco, Brazil Anais da ABC (AABC)
Gomes,Paula B.; Lira,Ana K.F.; Naud,Jean-Philippe; Santos,Andre M.; Pérez,Carlos D..
This study was designed to evaluate prey selection (type and size) by the octocoral Carijoa riisei at Porto de Galinhas beach, Northeast Brazil, relating prey availability in plankton with the content inside polyps. Diatoms and cyanophytes were the predominant items found in both polyp gastric cavity and plankton. A correlation between prey abundance in the plankton and in the gastric cavity of C. riisei polyps was observed. Mastogloia sp. showed the highest positive electivity index (0.99). Benthonic items were found, with 0.51% of total consumed preys. The size amplitude of prey items in the plankton was similar to those found inside the polyps, although the mean prey size in the polyps (112.7 µm) was significantly lower than the value found in the...

Association between deep-water scale-worms (Annelida: Polynoidae) and black corals (Cnidaria: Antipatharia) in the Southwestern Atlantic Rev. Bras. Zool.
De Assis,José Eriberto; Souza,José Roberto B. de; Lima,Manuela M. de; Lima,Gislaine V. de; Cordeiro,Ralf T.S.; Pérez,Carlos D..
ABSTRACT Polynoid scale-worms have been found living as commensals with deep-water antipatharians (commonly known as black corals) in the Potiguar Basin, off Rio Grande do Norte State, Northeastern Brazil. In this paper two polychaete species and four black corals species are redescribed. Benhamipolynoe cf. antipathicola and Parahololepidella cf. greeffi, and the black coral Stylopathes adinocrada Opresko, 2006 are recorded for the Southwestern Atlantic. Benhamipolynoe cf. antipathicola was first described from off New Zealand and the Malay Archipelago, as symbiont with the black coral Stylopathes tenuispina (Silberfeld, 1909). It was later reported for the North Atlantic, off Florida, associated with Stylopathes columnaris (Duchassaing, 1870). In our...
