  If you somehow got stuck in the middle of an oceanic abyss, the deepest part of the ocean, you'd have a few things to worry about. The lack of breathable oxygen, freezing cold, and these charming creatures, to name a few, but the huge amount of water pressure pressing down on you would definitely be the immediate threat. Since your body's internal pressure is so much less than the ambient pressure, your lungs would not have the strength to push back against the water pressure.
Paper Context: We show numerous projections from these neurons (see Ref. and FIGURE 3D3) to areas of the medulla regulating cardiorespiratory behavior. These small neurons also probably have very small axons see (FIGURE 3D4); if they are below 1 m in diameter, they are beyond the resolution of the light microscope, which implies their identify must be obtained by other means.
