Elephant seals stay at sea for between 2 and 8 months and dive continuously, spending 90% of their time underwater and averaging 20 minutes per dive with less than 3 minutes at the surface between dives. Their maximum dive duration is about 2 hours and they routinely feed at depths between 300 and 600 m, though they can exceed depths of 1600 m.
If you experience difficulty breathing, develop a severe cough, notice thick green or yellow mucus, run a fever, and/or feel extremely fatigued If your symptoms worsen instead of improve over time
The diver's exhaled breath at 29 to 32 °C (84 to 90 °F), does not have enough heat to compensate for the cooling effect of the expanding incoming air once the water temperature is much below 4 °C (39 °F), and once the water temperature drops below 4 °C (39 °F) there is not enough heat in the water to rewarm the regulator components fast ...
The oxygen affinity of the blood is related to lung volume. Where the lungs do not represent an oxygen store, the oxygen affinity is low to maximise the unloading of oxygen and to maintain a high tissue oxygen tension. Where the lungs are utilised as an oxygen store, the affinity is high and maximises uptake of oxygen from the alveolar volume. [13]
Recreational scuba diver The undersea kelp forest of Ana Capa off of the coast of Oxnard, California Diver looking at a shipwreck in the Caribbean Sea. Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance.

The ideal temperature for sleep is typically between 60°F and 67°F for most adults, says Martina Vendrame, M.D., neurologist and sleep medicine specialist at Lehigh Valley Health Network.
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ in bony fish (but not cartilaginous fish [1]) that functions to modulate buoyancy, and thus allowing the fish to stay at desired water depth without having to maintain lift via swimming, which expends more energy.
