common name for the Cyprinidae, a large family of freshwater fish which includes the carp (Cyprinus carpio), and of which there are some 2,400 species. Minnows have soft-rayed fins and teeth in the throat only.

They have fleshy, sucking mouths and are sluggish bottom feeders, eating small aquatic animals and plants. The white, or common, sucker, found throughout North America, is an important food fish with firm, sweet (though bony) flesh. Buffalo fish are large suckers whose coarse, bony, nutritious flesh is also much used as food in the central states. The bigmouth buffalo fish reaches 4 ft (120 cm) in length and 65 lb (29 kg) in weight, the smallmouth buffalo fish sometimes attains 20 lb (9 kg), and the black, or mongrel, buffalo fish is intermediate in size. Other suckers are known as red horses, carp suckers, and freshwater mullets. Suckers are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

(also, watershoot or water sprout), a shoot on the trunk or a thick branch of a tree that develops from dormant buds. Its leaves are larger than those of other shoots. Suckers are formed when a tree freezes, is pruned, or is given better lighting (for example, when neighboring trees are cut down). They are found frequently on oaks, maples, elms, black pop-lars, and Lombardy poplars. In fruit-bearing trees the suckers are usually destroyed because their growth decreases the number of flower buds, thereby decreasing also the fruit yield.
