ABSTRACT:

Regional migration of the copper shark Carcharhinus brachyurus was recorded for the first time in the Southwest Atlantic (SWA) from Argentina (latitude: –38.1037, longitude: –57.5371) to Brazil (latitude: –20.6833, longitude: –40.2846) as a result of a citizen science tagging project. The recaptured specimen was a female (103 kg weight), with 18 developing embryos within the uterus. The total distance was at least 2566 km, and it is the longest ever recorded for the species. Furthermore, it extends its northern distribution in the SWA.
