Rattlesnake Biology. Rattlesnake Biology. Rattlesnakes are usually identified by their warning rattle (a hiss or buzz) made by the rattles at the tip of their tails. A rattlesnake is born with a button, or rattler, and acquires a new rattle section each time it molts. Rattlesnakes also are distinguished by having rather flattened, triangular heads.
The sidewinder rattlesnake gives birth to up to 60 offspring. During the mating season, usually in the spring, males fight for the right to mate. The rivals raise up to 1 m (3.3 ft) over the ground, effectuating some undulatory movements, until one of the rival cedes. This is not really a fight, but rather a showoff. Births usually take place in August to October. Southern rattlesnake breed annually, but northern types, once in two years, and they give birth in June-July. 11. 29 species of rattlesnakes are known, differentiated through their colors and bony plates of the head.
