Three new sequences of Mitochondrial cytochrome c-oxidase subunit 2 (mtDNA cox-2) from C.pelagicum parasite of Spheniscus magellanicus, the Magelanicus penguin, Drive Pulley were determined from Brazilian waters.The sequences presented 99 and 98% of similarity with C.

pelagicum sequences from Argentina, deposited on GenBank for the same genetic region and with a strong statistical Brushes support inferred from the phylogenetic tree.The morphological and ultrastructural studies that were carried out confirmed the genetic analysis.
