... as an adaptation to aquatic hypoxia in the burrows. The acquisition of the novel respiratory capacity enables this species to stay in the burrows during low tide and extends the resident time in the mudflat, thereby increasing its chances of tapping the rich resources of the area. Specimens of Odontamblyopus...

... respiration in normoxic (air-saturated) water but when exposed to progressive aquatic hypoxia it becomes a metabolic O 2 conformer until facultative air breathing is initiated. The threshold (aquatic O 2 tension or partial pressure in mmHg) that elicits air breathing in S. marmoratus is higher in larger fish...
