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.
1 Garter snakes, rubber boas, and Western rattlesnakes bear live young from eggs retained in the body until hatching. 2  All other Washington snakes lay eggs in protected areas where the eggs receive enough external heat to hatch. 3  Young are born from July through September, and fend for themselves after hatching.
