Acanthopterygii refers to a grouping of teleost fishes united by the presence of a pelvic fin spine and reduction in size or number of free pelvic radials [1]. Recent phylogenetic studies indicate that the 'Acanthopterygii' are polyphyletic or paraphyletic within the Acanthomorpha (Li et al., 2009).
