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.
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 ...
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 ...
Bartholomea annulata is a species of sea anemone in the family Aiptasiidae, commonly known as the ringed anemone or corkscrew anemone. [2] It is one of the most common anemones found on reefs in the Caribbean Sea.
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]).
Cochliomyia is a genus in the family Calliphoridae, known as blowflies, in the order Diptera. Cochliomyia is commonly referred to as the New World screwworm flies, as distinct from Old World screwworm flies.
Introduced in the late 1800s, this invention combined the corkscrew and mechanical advantage in one device. In most examples the worm was attached to a stem, with a crank, inserted through a frame with a lever. In most examples the worm was cranked into the cork, and then a lever was pressed or pulled to extract the cork.
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 ...
