 The International Union for Conservation of Nature has therefore listed the finetooth shark under Least Concern, though no fishery data are available for this species off South America.This shark is not known to pose a danger to humans, though it snaps vigorously when captured and should be handled with caution.The finetooth shark was originally described as "Carcharias (Aprionodon) isodon" by French zoologist Achille Valenciennes, in Müller and Henle's 1839 "Systematische Beschreibung der Plagiostomen".
