How do king cobras remove waste from their system?

King cobras, like other snakes, have small openings horizontally on the underside of their bodies, near thee base of their tails. These openings are called cloaca, and are covered by a half-moon-shaped scale that is called the anal plate. When the king cobra is ready to excrete, it releases uric acid through the cloaca, which is liquid waste and a more efficient form of solid waste that helps reduce water loss and prevent dehydration.
