Of the several methods that can be used for species identification (see Lockely & Bardsely, 2000), DNA Barcoding is the species determination using a standard DNA segment, and has been widely applied to identify species in a variety of taxa (e.g. Bucklin, Steinke,& Blanco-Bercial, 2011; Frézal & Leblois, 2008; Grant & Linse, 2009;Hajibabaei, Singer, Hebert, & Hickey, 2007; Holmes, Steinke, &Ward, 2009; Radulovici, Archambault, & Dufresne, 2010; Valentini,Pompanon, & Taberley, 2009; Waugh, 2007). Wong and Hanner (2008) used DNA Barcoding for seafood authentication in North
America and detected that 25% of the samples were mislabeled. To date, most seafood authentication studies have been centered in the identification of fish species (Filonzi et al., 2010; Marko et al.,2004; Ogden, 2008; Smith, McVeagh, & Steinke, 2008) with a significant gap in the rest of the marine taxa exploited as seafood (but see Espiñeira, Vieites, & Santaclara, 2010; Maldini, Marzano,González, Papa, & Gandolfi, 2006; Ortea, Cañas, Calo-Mata, Barros-Velásquez, & Gallardo, 2010; Pascoal et al., 2011; Zhang, Tang,Ding, & Zhang, 2009).
