Sharpnose sharks (Genus: Rhizoprionodon) experience extensive fishing pressure throughout their ranges in the Atlantic Ocean, and as such it is important to understand the degree to which intraspecific populations interact across a spatial gradient. The Atlantic sharpnose shark Rhizoprionodon terraenovae and Caribbean sharpnose shark R. porosus share similar appearance and spatial presence within the Gulf of Mexico (GOM), though previously only R. terraenovae has been observed north of the Bahamas. We assessed the population structure of R. terraenovae using the mitochondrial control region (650 bp). Our results indicate significant genetic structure (FST = 0.049, P The accepted manuscript in pdf format is listed with the files at the bottom of this page.
