South American lungfish are dependent on being able to breathe air through their lungs from time to time, otherwise they will suffocate. As a result they can also survive in water which is very low in oxygen and, like their African cousins, survive periods of drought buried in mud. However, if the waters they live in dry out completely they are unable to survive. Parental care is carried out by the male of the species, which during this period grows tufted attachments which are well supplied with blood on its ventral fins. These absorb carbon dioxide and emit oxygen which improves the flow of oxygen to the nest.
