Long-term subae lal survival has been anecdotally noted
in the staghorn sculpin, Leptocottus armatus. In this study,
I quantified this phenomenon physiologically by examining the
following parameters: standard metabolic rate and indications
of reduced standard metabolic rate during subaerial exposure;
capacity for and mechanism(s) of oxygen consumption in air;
capacity for anaerobic production of lactate and/or ethanol;
and blood pH. The staghorn sculpin appears well-suited for
the subaerial exposure it experiences in nature. Mean
subaerial survival time was 6 hours which would enable fish to
survive intertidal stranding. Staghorns breathe air through
well-supported gills and supplement depressed rates of
subaerial aerobiosis by anaerobic production of lactic acid.
Most remarkably, the staghorn sculpin may also substantially
reduce minimal energy expenditure requirements during periods
of hypoxia by reducing resting metabolic rate. / Graduation date: 1991
