Hoarseness is generally caused by irritation of, or injury to, the vocal cords. The larynx (also referred to as the voice box), is the portion of the respiratory (breathing) tract containing the vocal cords. The vocal cords are two bands of muscle that form a V inside the larynx.
In some species babies are born alive. Other species lay eggs. In a strange combination of the two, some snakes have eggs that stay in their bodies until the eggs hatch and then the babies are born. Snakes can have anywhere from one to 150 baby snakes at a time.
Life Cycle of Rattlesnakes: While some types of snakes lay eggs, a rattlesnake's young are born alive. The rattlesnake does have eggs, but the eggs are carried inside the female's body. Once the eggs are fertilized, they are carried for approximately 90 days.
