Патагонский морской ангел[1], или аргентинская скватина[2] (лат. Squatina argentina) — вид рода плоскотелых акул одноимённого семейства отряда скватинообразных. Эти акулы встречаются в западной части Атлантического океана на глубине до 400 м. Максимальная зарегистрированная длина 170 см. У них уплощённые голова и тело, внешне они похожи на скатов, но в отличие от последних жабры скватин расположены по бокам туловища, рот находится в передней части рыла, а не на вентральной поверхности. Эти акулы размножаются путём яйцеживорождения. Рацион состоит из небольших рыб и беспозвоночных. Не представляют интереса для коммерческого рыбного промысла[3].
