The Sperm Whale’s Teeth Revisited
2016Let me return briefly to the crime scene of the prologue. I went back later that December Friday to see the whale’s body again. Hurrying with trepidation and excitement, I came up to the bank of sand dunes that overlooked its sandy open grave where I had stood, awestruck, that morning. This wretched, ransacked body, so lifeless a few hours earlier, was

Ligand Migration in Sperm Whale Myoglobin
Biochemistry, 1997Geminate oxygen rebinding to myoglobin was followed from a few nanoseconds to a few microseconds after photolysis for more than 25 different oxymyoglobin point mutants in the presence and absence of 12 atm of xenon. In all cases, two relaxations were observed: an initial fast phase (half-time 20 ns) and a slower, smaller phase (half-time 0.5-2 micros).

Function of the Spermaceti Organ of the Sperm Whale
Nature, 1970THE structure of the head of the sperm whale (Physeter catodon) was described in outline by Pouchet and Beauregard1–3 and by Raven and Gregory4, but the function of the large, wax filled spermaceti organ and related structures is not known although several theories4–6 have been advanced.

The Sounds of Sperm Whale Calves
1988The development of the click sounds of sperm whales (Physeter catodon) has been investigated through comparisons of these vocalizations from calves of different sizes. The observations include sounds from four small stranded calves held for short periods in aquaria at Miami, Florida, and Seattle, Washington, and in a bay on Long Island, New York. These

Acoustics and the Behavior of Sperm Whales
1980The first good recordings of underwater sperm whale sounds that we have were made 27 years ago (22 April 1952, R/V Caryn at 38°29′N, 69°29′W) and five years later the sounds were identified definitely and described (Worthington and Schevill 1957). At every opportunity since then, we have stopped with these whales and listened underwater (Watkins 1977).
