William Healey Dall
William Healey Dall (August 21, 1845 – March 27, 1927) was an American naturalist, a prominent malacologist, and one of the earliest scientific explorers of interior Alaska. He described many mollusks of the Pacific Northwest of America, and was for many years America's preeminent authority on living and fossil mollusks. Dall also made substantial contributions to ornithology, zoology, physical and cultural anthropology, oceanography and paleontology. In addition he carried out meteorological observations in Alaska for the Smithsonian Institution. Biography Early life Dall was born in Boston, Massachusetts. His father Charles Henry Appleton Dall, (1816–86), a Unitarian minister, moved in 1855 to India as a missionary. His family however stayed in Massachusetts, where Dall's mother Caroline Wells Healey was a teacher, transcendentalist, reformer, and pioneer feminist. In 1862, Dall's father, on one of his few brief visits home, brought his son in contact with some na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whorl (mollusc)
A whorl is a single, complete 360° revolution or turn in the spiral growth of a mollusc shell. A spiral configuration of the shell is found in numerous gastropods, but it is also found in shelled cephalopods including '' Nautilus'', '' Spirula'' and the large extinct subclass of cephalopods known as the ammonites. A spiral shell can be visualized as consisting of a long conical tube, the growth of which is coiled into an overall helical or planispiral shape, for reasons of both strength and compactness. The number of whorls which exist in an adult shell of a particular species depends on mathematical factors in the geometric growth, as described in D'Arcy Wentworth Thompson's classic 1917 book '' On Growth and Form'', and by David Raup. The main factor is how rapidly the conical tube expands (or flares-out) over time. When the rate of expansion is low, such that each subsequent whorl is not that much wider than the previous one, then the adult shell has numerous whorl ...
