The color of the fish greatly varies—the color of its back and upper sides can be dark green, grey, coppery brown, or even black, while the lower sides are lighter and give way to the white underbelly. When spawning, these colors darken and intensify. Spawning males develop distinctly colored bands along the sides of their body as well as coarse bumps (tubercles) on the head and their anal and caudal fins. Young white suckers are lighter in overall color and have three very distinct dark spots on their sides.
Typically, white suckers grow to be 12 to 18 inches in length, but they can get as big as 25 inches long. They weigh anywhere from 2 to 6 pounds. White suckers have 55-85 lateral line scales and 10-13 dorsal rays.
Habitat
For the most part, the white sucker inhabits the upper Midwest and Northeast of North America, but it has been found as far west as New Mexico and as far south as Georgia.
