Phylogeny of the Serrasalmidae (Characiformes) based on mitochondrial DNA sequences
Genetics and Molecular Biology, 2008 Previous studies based on DNA sequences of mitochondrial (mt) rRNA genes showed three main groups within the subfamily Serrasalminae: (1) a "pacu" clade of herbivores (Colossoma, Mylossoma, Piaractus); (2) the "Myleus" clade (Myleus, Mylesinus, Tometes ...

CYTOLOGIA, 1994 The chromosomal characteristics of two species belonging to the genus Serrasalmus (S. spilopleura and S. marginatus) from the Parana basin were studied. The two species showed the same diploid chromosome number 2n=60. However, they showed peculiarities in karyotypic structure that permit their identification, indicating that pericentric inversions were
