Baleen and Sperm Whales

2019
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, 1990
This 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 ...

Self-association of sperm whale metmyoglobin

Archives of Biochemistry and Biophysics, 1984
The 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 ...

Ligand Migration in Sperm Whale Myoglobin

Biochemistry, 1997
Geminate 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).

The Sperm Whale’s Teeth Revisited

2016
Let 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

Whale Worm Sperm Factories [PDF]

Science, 2007
SOCIETY FOR INTEGRATIVE AND COMPARATIVE BIOLOGY MEETINGPHOENIX, ARIZONA-- At the Society for Integrative and Comparative Biology meeting, held here from 3 to 7 January, researchers described male tubeworms with a distinctly odd but highly targeted development: They fail to mature, except with respect to their ability to produce sperm. ([Read more][1].)

Binding of Cyclopropane to Sperm Whale Myoglobin

Nature, 1967
THIS article follows reports of the binding of xenon, an anaesthetic agent, to sperm whale met and deoxymyoglobin1,2. X-ray diffraction analysis showed that a single xenon atom binds to the same specific site in both derivatives. This site is located at a cavity in the interior of the molecule, about equidistant from the haem linked histidine and one ...
