Oxygen minimum laye: vertical distribution and respiration of the mysid Gnathophausia ingens.

The large mysid crustacean Gnathophausia ingens (between 35 and 125 millimeters long) lives at oxygen concentrations between 1.25 and 0.20 milliliter per liter along the coast of California. It lives aerobically at these low oxygen concentrations by regulating its rate of oxygen consumption in water having down to and below 0.26 milliliter of oxygen per liter.
