What the sources say
Venom: “Nebraska is home to nearly 30 different snakes, 25 that are non-venomous and four that are venomous. … Massasauga (Sistrurus catenatus)” (Nebraska Game and Parks Commission)
Habitat: This snake prefers wet areas such as prairies and grasslands. One key feature that needs to be in any habitat these animals are found is crayfish burrows. Massasaugas will use them for hibernation during the winter months. Many of this snake’s natural habitat has been converted to agricultural lands so they have been reduced to live around artificial ponds and lakes. (Nebraska Game and Parks Commission)

Snakes people confuse
Black Racer or Timber rattlesnake?
Photo: Everglades NPS from Homestead, Florida, United States · Public domain · Wikimedia Commons
The copperhead's head is coppery with no marks; the milksnake's head is light with brownish marks (Pennsylvania). Tennessee: copperhead has a copper-colored, unmarked head and triangular shapes on the side of the body. Pennsylvania says the eastern milksnake is the snake most often killed by mistake for a copperhead. Belly colour is not used here: Pennsylvania's own pages describe the copperhead belly two different ways (uniform cream in one account, mottled white to gray in another).
TWRA: the racer lacks the coachwhip's reddish tint along the sides of the tail; an all-black coachwhip is distinctly lighter or reddish toward the rear. Oklahoma: the coachwhip is much larger.
Gopher snake (gophersnake) or Rattlesnakes?
Photo: National Park Service from USA · Public domain · Wikimedia Commons
WDFW: gopher snakes lack a rattle and facial pits and have smaller, square back spots. NPS Cabrillo: the gopher snake's tail is long, skinny and pointed with no rattle, its head is about as slender as its neck (rattlesnakes have large spade- or triangle-shaped heads), and its back pattern is a rectangular chain rather than the circles or diamonds of a rattlesnake. Caution: a defensive gopher snake flattens its head into a triangle and vibrates its tail, so do not rely on head shape or sound alone.
