A sucker rod is a steel rod, typically between 7 and 9 metres (25 and 30 ft) in length, and threaded at both ends, used in the oil industry to join together the surface and downhole components of a reciprocating piston pump installed in an oil well.
The polished rod is connected to a long string of rods called sucker rods, which run through the tubing to the down-hole pump, usually positioned near the bottom of the well. Picture of a pump jack used to mechanically lift liquid out of the well if there is not enough bottom hole pressure for the liquid to flow all the way to the surface.

Like most other members of the sucker family, Catostomidae, detritus and algae are also staples of the golden redhorse's diet. It is a bottom-feeding species that is ...
Sometimes it competes with other sucker species and redhorse for breeding habitat. During the egg-laying process, daces, minnows, and chubs will sometimes forage on the freshly expelled eggs. [3] Spawning takes place in shallow water riffles usually during May, when the water temperature is about 15 °C (59 °F).
The bigmouth buffalo's native distribution is confined to the countries of Canada and the United States of America. [18] It is native to the Red River of the North and Mississippi River drainage basins, from Manitoba, Canada, and North Dakota, United States, to the Ohio River and south in the Mississippi River system to Texas and Alabama.
The sucker has a small black skull and two air-bladders, although the air-bladders are reduced in size. The fish is small in size, and generally does not exceed seven inches.

The spotted sucker (Minytrema melanops) is a species of sucker (fish) that is native to eastern North America. The spotted sucker inhabits deep pools of small to medium rivers over clay, sand or gravel. They are occasionally found in creeks and large rivers. Through its life stages, the spotted sucker goes from a mid-depth predator to a bottom ...
