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.
The sperm either fertilize the eggs directly or go to a storage receptacle. Some female snakes can store viable sperm for months to years, and don't need to mate each time they produce fertile eggs. Most snakes lay eggs, but some species keep the developing embryos in the oviduct and release living young.
