As an asides, this is interesting:

Liggins carried out research and made discoveries in many other areas, including early work on fertility as well as studying the placenta and the mechanisms involved in fetal breathing. In the late 1970s he worked with others in the Antarctic to try to work out how seals could hold their breath for so long, and how pregnant female seals provided their fetuses with sufficient oxygen. He found that the seals had higher levels of cortisol, and that those that dived the deepest had the highest levels – suggesting that the hormone helps them withstand the pressure at depth. He gained numerous awards and honours, becoming a Fellow of the Royal Society in 1980 and being knighted in 1991. In 2001 the University of Auckland named its new biomedical and clinical research centre the Liggins Institute. He died in the summer of 2010 at the age of 84.
