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.
After young snakes or born or hatched, their parents do not take care of them, they are left to fend for themselves. Ovoviviparous snakes hold their eggs inside of their stomachs until the eggs are ready to hatch. This helps protect them fully from predators.
