The Eastern Diamondback Rattlesnake is the largest and most dangerous of Florida’s native snakes, and is one of the most poisonous snakes of the world. It is large in size, has a high quantity of venom, aggressive defensive tactics and tremendous striking speed, thus making this snake one to be treated with extreme caution. Although it may attain a body length of over eight feet, it is rare to find an Eastern Diamondback over seven feet long. Rattlesnakes feed on small warm-blooded animals, mainly rabbits, squirrels, rats, mice, and sometimes birds. When disturbed, rattlesnakes assume a defensive position with the body coiled around and the head and neck raised in an S-position. From this stance, the rattler can deliver the venomous strike. It almost always gives a warning rattle of the tail first. The Eastern Diamondback occurs in every Florida county and prefers rural scrub pine areas. Average adult size is 36-72 inches, and the record is 96 inches.
