There are four species of rattlesnake with the black and white bands on the tail - the eastern diamondback, the western diamondback, the red diamondback and the Mojave rattlesnake. The bands indicate nothing about the age of the snake. They have the same number of bands as adults that they had when newborn.
The diamondback rattlesnake got its name from the diamond shaped pattern on its back.
Male and female rattlesnakes look very similar. Only a snake keeper with a lot of experience would be able to tell the difference in gender without probing the snake. The length, width and taper of the tail would give a trained keeper a good idea of gender.
Rattlesnakes originated in the Americas, primarily along the West Coast where the landscape is drier. There are several prominent rattlesnake types, including Timber Rattlesnakes which are found in the Northeastern region of America, Diamondback Rattlesnakes from the Mid-South and Southwestern regions of America, and the Cane Break Rattlesnake from the Mid-South and Southeastern regions of America.
The Eastern Hognose snake is known to mimic rattlesnakes by flattening their head, hissing, and even vibrating their tail when threatened. However, they are non-venomous and mostly rely on bluffing to deter predators.
Some other snakes that rattle their tails to warn off potential predators include the Massasauga rattlesnake, the Western diamondback rattlesnake, and the Timber rattlesnake. These snakes use their tail rattle as a form of defense when feeling threatened.

There is no single snake that fits this description. There is the Arizona black rattlesnake but it is a heavy-bodied snake as are most rattlesnakes. (See image above.) There is, however, the black rat snake which is long and slender. It does not have a rattle. However, when frightened it will vibrate its tail much like a rattlesnake, and this can sound like a real rattler if the snake happens to be on some dry leaves.
