Given their resilience and adaptability, these snakes can live up to 20 years in the wild. Viviparity is a fascinating process that allows for reproduction. where the female keeps the growing embryos inside her body and cares for them until they are born alive. This special method of reproduction guarantees the survival of the progeny, giving them an advantage in the dangerous journey through life.

In Fayetteville, NC, during some downtown revitalization some years ago, a row of very older houses on Person St. were demolished by the city for the new fire station that was relocated a 1/4 mile from in town to it's current location. In the process of removing these antiquated structures, the city workers came across a 10 ft. eastern diamond back that they killed & the city newspaper entitled Fayetteville Observer invetigated & took photographs of the 3 workers standing beside each other holding at least a 3 ft. section of the dead snake. No one one believed the story at 1st, until it was displayed in the local newspaper, & then everyone was paranoid as to how such a large snake could have been living so close to the downtown area without anyone seeing it. According the account, there was a healthy rat/mice population that emerged during demolition.

My m-i-law drove her mother to a remote field to check the crop in the 1960's in W Hickman Co, TN. Returning to the car, they observed the tall hay moving almost flat in a very long serpentine pattern. Terrified m-i-l crawled over the car thru an open car window on the opposite side. Both died convinced it was an E Diam Rattlesnake @ least 8 ft of huge girth, based on damage to hay field & movement pattern. Given remoteness & ideal resources, & that both had been born & raised around plentiful snakes, fam believes it was prob an undocumented E Diam world record. Timbers were very common, an occas pygmy, but E Diams were present but rarely seen & greatly feared. My bro-i-law & I are prob the only living fam who heard this discussed many times over the yrs.
