EASTERN MASSASAUGA RATTLESNAKES HAVE HEAT-SENSITIVE PITS NEAR THEIR EYES THAT ALLOW THEM TO SENSE THEIR PREY

  Otherwise called the "marsh rattler," the eastern massasauga diamondback is a subspecies of the massasauga, which ranges from north Mexico to south Canada. The subspecies' range is to some degree more restricted: south Ontario to eastern Missouri. "Massasauga" is gotten from the Chippewa dialect and interprets as "incredible waterway mouth," probably alluding to the snake's inclination for wet environments. Eastern massasaugas sleep through winter and late-winter in marshes, bogs and wet prairie situations, heading out up to 1.6 miles to drier summer territories. They regularly winter in crawfish gaps, which habitually surge, resting with their head over the water and body submerged. They likewise rest under logs, tree establishes and in little warm blooded creature tunnels. Not at all like different diamondbacks, they rest alone. 

A pit snake, eastern massasauga diamondbacks have warm delicate pits close to their eyes that let them sense the nearness of prey. They can likewise track prey by sight, vibration and warmth. Eating for the most part little warm blooded animals like voles, deer mice and vixens, the poisonous snake frequently strikes, infuses its venom, at that point withdraws and sits tight for the creature to kick the bucket or be quelled before eating it. Its venom is profoundly poisonous, yet conveyed in little dosages. In people, chomps will deliver swelling, queasiness and extraordinary agony. 

A contender for the government Endangered Species List, the eastern massasauga is recorded as Endangered, Threatened or a Species of Concern in each state and area in its range. The principle risk to the subspecies is misfortune and fracture of natural surroundings.
