Cochliomyia hominivorax, the New World screwworm fly, or simply screwworm or screw-worm, is a species of parasitic fly that is well known for the way in which its larvae (maggots) eat the living tissue of warm-blooded animals.
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
A worm is a device used to remove unspent powder bag remnants from a cannon or other piece of muzzle-loading field artillery. [1] It usually took the form of a double or triple [ 2 ] corkscrew-shaped piece of iron on the end of a long pole that could be twisted down the barrel to pick up any debris left over from the previous firing of the ...
Henshall was awarded on 24 August 1795 the first patent for a corkscrew. It had a fixed disc or button between the worm and the shank, so that the worm would not advance further when the button reached the top of the bottle. [2] [3] [4] It is known as the Henshall Button Corkscrew, and was manufactured by Matthew Boulton. [5]
A corkscrew is a tool for drawing corks from wine bottles and other household bottles that may be sealed with corks. In its traditional form, a corkscrew simply consists of a pointed metallic helix (often called the "worm") attached to a handle, which the user screws into the cork and pulls to extract it. Corkscrews are necessary because corks ...

[1] [2]At first glance, this fire worm looks like a centipede with its elongated and flattened appearance, multiple segments, white silks, and parapodia and gills located on the side of its body.

Zoophycos occurs in two forms, one planar, and one which resembles a corkscrew. [2] In the latter helicoidal form, successive turns have larger or smaller radii. A marginal tube surrounds the perimeter of the corkscrew, linked to the vertical shaft that connects the burrow to the surface. Spreiten occur between the marginal tube and the ...
