    during a dive, limits the absorption of nitrogen and decreases the probability of decompression sickness in these organisms. The lack of gas exchange during a dive reduces the amount of nitrogen the blood absorbs (McDonald and Ponganis, 2012). Surfactants are also produced in the lungs to keep them from adhering together and allows the organism to refill its lungs at the surface (Miller et al., 2004). Decompression sickness is unusual in diving mammals, but may occur under specific circumstances
