Wikipedia Abstract

The shortspine thornyhead (Sebastolobus alascanus) is a species of fish in the Sebastidae family. It is sometimes referred to as the "idiot fish" or "idiot cod" due to its large oversize head/eyes. It is found in Canada, Russia, and the United States. 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 is
