drainage. Both state agencies are involved in massive eradication efforts to prevent snakeheads from reaching the main rivers of these drainage basins. Snakehead fish have a diet very similar to that of a Largemouth Bass. Their diet consists of crayfish, other native fish, snakes, small mammals, frogs, turtles, etc. The reason that snakeheads are bad is because they eat native fish that will not eat them.

Conservation Theory and Management | Cave Formation and the Ecosystem Within | By: Robert Luncsford | | The formation of a cave begins when rainwater falling through the atmosphere absorbs carbon dioxide causing it to become acidic. The rainwater then passes through the soil collecting more carbon dioxide from dead plant life and animals. The acidity allows the rainwater to chemically react to limestone or dolomite rock which starts the formation of caves through a process called chemical
