Anatomical differences among specimens of Pinctada imbricata Röding, 1798 from different South American localities

Abstract: In the present study, we compared the internal and external anatomy of pearl oyster (Pinctada imbricata Röding, 1798) from some South American localities, including Venezuela and several regions of Brazil. The anatomical data shows non-geographical variations characterized by variable outline in adults, different degrees of posterior auricle shell development and mantle papillae ranging from normal to digitiform. The geographical variations can be divided into two major groups: the Venezuelan group presents a … Show more

“…The Atlantic pearl oyster, Pinctada imbricata (RODING, 1798), is a relative common filter-feeding epibenthic bivalve and one of the most biologically and economically important species belonging to the family Pteriidae, given its extensive use in human feeding and pearl cultivation (URBAN, 2000;VILLALOBOS and ELGUEZABAL, 2001;MARQUES and BARBIERI, 2015). Though some authors state that its southernmost occurrence is Venezuela (SHIRAI, 1994;O' CONNOR and LAWLER, 2004;WADA and TEMKIN, 2008; see also the World Register of Marine Species database, BOUCHET and ROCROIT, 2013).…”
