| Deskribapena: | Sharks (Chordata: Chondrichthyes) can live in diverse environments and have distinct lifestyles. Several species migrate and are widely distributed worldwide, particularly deep-sea sharks. The Goblin shark (Mitsukurina owstoni) is a deep-sea shark species characterized by its elongated snout and protrusible jaws. The goal of this study was to review the global distribution of M. owstoni using QGIS, based on information from scientific publications in GBIF, BOLD Systems, and GenBank. Additionally, using DNA barcoding, two newly recorded individuals collected in Madeira, Portugal, in 2022, were analyzed, and global levels of genetic diversity and population differentiation were calculated, considering all available DNA sequences of this species. This showed that the Goblin shark is distributed globally and genetic diversity between individuals is low, with only two distinct haplotypes, one of which is present globally. In summary, there is probably only one active population, with no geographic structure and high connectivity between locations, due to this species’ migratory behavior. |
