Fun fact! Scientists believe rattlesnakes may have evolved their “rattles” to reduce the risk of being stepped on and crushed by bison! The rattle is formed of modified scales that create a series of hollow, interlocked keratin segments that vibrate against each other when special “shaker” muscles in the tail are contracted, producing the characteristic rattling sound. The muscles that cause the rattle to shake fire around 50 times per second!

Rattlesnakes do not seek out humans and will normally flee when approached or give a warning rattle is they are unable to find shelter. Although they are highly venomous, on average less than one person per year in the US dies from a rattlesnake bite – compared with over 50 people who die annually as a result of an allergic reaction to a bee sting.

Rattlesnakes live in a wide variety of habitats but tend to avoid developed areas and wide open spaces where they cannot hide from predators. Mass killings during events like rattlesnake round-ups, deliberate extermination campaigns, and habitat loss all pose severe threats to rattlesnake populations in many areas, and several species including the timber rattlesnake, massasauga, and canebrake rattlesnake are listed as threatened or endangered in many U.S. states. https://www.facebook.com/photo.php?fbid=...
