Galeocerdo cuvier[2] est species selachimorphorum ordinis Carcharhiniformium et sola generis Galeocerdinis species exstans. Magnus macropraedator usque ad 5 metra longus crescere potest.[3] Multitudines in multis aquis tropicis temperatisque inveniuntur, praecipue circa insulas medii Oceani Pacifici.

Galeocerdo cuvier iuvenis in Insulis Bahamensibus.

Galeocerdo cuvier est venator solitarius et plerumque nocturnus. Variissimam omnium selachimorphorum diaetam insigniter habet, nam crustaceis, piscibus, pinnipediis, avibus, dodecapodiformibus, testudinibus, hydrophiinis, odontocetis,[4] atque adeo minoribus selachimorphis vescitur. Fama est etiam quisquilias comedit,[5] varias res ab hominibus factas consumens, quae in eius stomacho manent. Galeocerdines cuvier, quamquam praedatores apicales, aliquando a gregibus orcorum capiuntur. Haec species in discrimen adducta habetur propter pinnationem selachimorphorum et piscationem ab hominibus effecta.

De impetibus exitialibus in homines, Galeocerdino cuvier est secundus solum a Carcharodonte carchariate.
