AbstractIn 2016, two adult male sperm whales beached off of Yangkou Port in Nantong City, Jiangsu Province, China. The local government planned to preserve them as specimens, one was entrusted to Dalian Hoffen Biological Co., Ltd., and thus became the first sperm whale to be preserved by plastination.

The Journal of the Acoustical Society of America, 1977
Short series of 3 to 40 or more clicks are produced by sperm whales, Physeter catodon, in stereotyped repetitive sequences or codas. The temporal click patterns in codas appear to be unique to individual whales over at least a few hours. It is suggested that sperm whale codas serve as a means of individual acoustic identification.

Bioacoustics, 2005
ABSTRACT Sperm whale Physeter macrocephalus L. clicks have been studied for nearly fifty years, during which time great efforts have been made to understand the functions and production mechanisms of this sound. Other than clicks, sperm whales may also produce low intensity sounds arranged in short sequences, named trumpets, which have been recorded ...

Chromosomes of the Sperm Whale
Nature, 1965THIS report describes the results of a chromosomal analysis of the sperm whale by the method of leucocyte tissue culture. During July and August, 1964, fresh sterile blood was obtained at sea for various research purposes from sperm, finback, and sei whales (Physeter catodon, Balaenoptera physalus and B.

Sperm whale clicks: Directionality and source level revisited
The Journal of the Acoustical Society of America, 2000In sperm whales (Physeter catodon L. 1758) the nose is vastly hypertrophied, accounting for about one-third of the length or weight of an adult male. Norris and Harvey [in Animal Orientation and Navigation, NASA SP-262 (1972), pp. 397–417] ascribed a sound-generating function to this organ complex.

GENITAL PAPILLOMATOSIS IN SPERM WHALE BULLS
Journal of Wildlife Diseases, 1987Examination of 31 male sperm whales (Physeter catodon) caught off the western coast of Iceland revealed three cases of genital papillomatosis involving the unsheathed penis. One subadult and two sexually mature bulls were affected. Gross lesions resembled papillomas common in terrestrial mammalian species.

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).

Self-association of sperm whale metmyoglobin
Archives of Biochemistry and Biophysics, 1984The solution behavior of sperm whale metmyoglobin in 0.15 I phosphate-chloride buffer, pH 7.2, has been examined by sedimentation equilibrium, frontal gel chromatography, and sedimentation velocity. Results obtained from all three studies are shown to be consistent with a self-association model in which dimerization of the myoglobin is governed by an ...

The International Whaling Commission (IWC) is holding a special meeting in Japan next week. Two major tasks for the meeting will be to set catch limits for sperm whale stocks in the North Pacific and to review the status and catch limits of sperm whales in the Southern Hemisphere.
