The line of sucker rods is represented in this diagram by the solid black line in the center of the well. 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.
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 smallmouth buffalo's diet is primarily that of a detritivore, using its ventral sucker mouth to pick up vegetation and other organic matter from the bottom of its habitat, often scraping algae off of rocks. It is also quite the invertivore, consuming zooplankton, insect larvae, mollusk larvae, and small crustaceans.

Bacterial cellular morphologies are the shapes that are characteristic of various types of bacteria and often key to their identification. Their direct examination under a light microscope enables the classification of these bacteria (and archaea). Generally, the basic morphologies are spheres (coccus) and round-ended cylinders or rod shaped ...
Catostomus from different species of the genus are known to readily hybridize with each other. [3] The fish was used as a study object by biologists, revealing that fish hybridization can vary greatly from place to place.
Phenacobius, the suckermouth minnows, is a genus of cyprinid fishes endemic to the United States.Historically the suckermouth minnow was not found as far eastward as Ohio, now they seem to be a stable species living throughout the Midwest and parts of southern states such as Texas, New Mexico, and Alabama.
