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.
Some species give birth to live young, while others lay eggs. Oviparous: Most snakes (about 70% of them) are oviparous, which means they lay eggs. The eggs must then be incubated, or kept warm, until the hatchlings are ready to emerge from the shell. Nearly all members of the Colubridae family lay eggs.
