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.

Sperm whales generate multi-pulsed clicks for echolocation and communication with an inter-pulse interval (IPI) determined by the size of their hypertrophied sound producing nose.

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 ...

During the night of 13 to 14 March, the Nautilus continued on its route southwards. I thought that once at Cape Horn it would set sail for the west, in order to head for the seas of the Pacific and thus complete...

Aerial behaviour in sperm whales
Canadian Journal of Zoology, 1990This paper examines the nature and context of breaching (leaping from the water) and lobtailing (thrashing of flukes onto the water surface) in sperm whales (Physeter macrocephalus) using data principally collected off the Galápagos Islands. Animals generally breached on their sides at an angle of 30–50° to the water surface and with about 50–100% of ...

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 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
