Mammalian diving reflex: "The mammalian diving reflex is a reflex in mammals which optimizes respiration to allow staying underwater for extended periods of time. It is exhibited strongly in aquatic mammals (seals, otters, dolphins, etc.), but exists in weaker versions in other mammals, including humans, including babies up to 12 months old (see Infant swimming)."
