Figure 61 in Comprehensive phenotypic phylogenetic analysis supports the monophyly of stromateiform fishes (Teleostei: Percomorphacea)

Figure 61. The muscular attachment of the pharyngeal-sac raker in Stromateiformes. Raker bases are visible after removal of the external most layer of the sphincter oesophagi. A, in the ariommatid Ariomma melana (MZUSP 123246), rakers are large, round and with partly overlapping bases, forming a scale-like pattern. B, in the tetragonurid Tetragonurus cuvieri (MZUSP 123241), rakers are small, round, poorly ossified and with non-overlapping bases. C, D, in both the nomeid Nomeus gronovii (MZUSP 67590; C) and the stromateid Stromateus brasiliensis (MZUSP 51279; D), the raker bases are large, well ossified and stellate. Scale bars: 0.5 mm.
