Sebastolobus alascanus là một loài cá thuộc họ Scorpaenidae. Nó được tìm thấy ở Canada, Nga, and Hoa Kỳ. Adult S. alascanus live predominantly in the oxygen minimum zone (OMZ), and thus require specific adaptations/exaptations in order to overcome the problems posed by the extremely low levels of oxygen saturation. Allowing for an increased ventilation frequency during exposure to progressively hypoxic conditions, as compared to its more shallow relative Scorpaena guttata, enables S. alascanus to compensate for the inherent low concentrations of oxygen in the OMZ. Further, heightened levels of lactate dehydrogenase, specifically the anaerobic isoform- LDH-A in the heart and muscles of S. alascanus, suggests an adaptive mechanism for ATP production during low oxygen availability.
