Abstract
    Species identification based on morphological characteristics is often challenging. Therefore, genetics are used to assess species identification and population structure. The goal of this research is to study the genetic structure and migration patterns for Octopus mimus along the Peruvian coast. Two types of genes are used, the COI-gene and microsatellites. Because they have different inheritance patterns, both are assessed. Several samples of Octopus mimus were collected along the coast of Peru from fishermen. These samples came from different biogeographical regions, the Panamanian province, the equatorial front, and the Peruvian-Chilean province. For both datasets, a significant genetic structure was found using AMOVA’s. However, no significant differentiation was seen between the different biogeographical regions. With microsatellites, a larger migration was observed. This migration pattern went against the major currents, while the migration for the COI-gene went with major currents. The differences found here are largely to be attributed to the different inheritance patterns between both markers.
