We report the presence of Blackfin Goosefish, Lophius gastrophysus Miranda Ribeiro, 1915, in Mexican waters of the Gulf of Mexico, expanding its known distribution to the south of the Gulf by approximately 400 km. This report is based in one specimen (712 mm total length, 593 mm standard length, and 7,500 g in weight) captured off the coast of Veracruz. We present the morphometric and meristic data of the specimen and compare it with those previously published.
