Alligator Eats An Alligator

Anatomy
Alligators, much like birds, have been shown to exhibit unidirectional movement of air through their lungs. All other amniotes are believed to exhibit bidirectional, or tidal breathing. For a tidal breathing animal, such as a mammal, air flows into and out of the lungs through branching bronchi which terminate in small dead-end chambers called alveoli. As the alveoli represent dead-ends to flow, the inspired air must move back out the same way that it came in. In contrast air in alligator lungs makes a circuit moving in only one direction through the parabronchi. The air first enters the outer branch, moves through the parabronchi, and exits the lung through the inner branch. Extensive vasculature around the parabronchi are where oxygen exchange takes place.
They have muscular flat tails that propel them while swimming.
There are two kinds of white alligators, albino and leucistic. These alligators are practically impossible to find in the wild. They could survive only in captivity and are few in number. The Aquarium of the Americas in New Orleans has leucistic alligators found in a Louisiana swamp in 1987.
