Sloughs, or free-flowing channels of water, develop in between sawgrass prairies. Sloughs are about deeper than sawgrass marshes, and may stay flooded for at least 11 months out of the year and sometimes multiple years in a row. Aquatic animals such as turtles, alligators, snakes, and fish thrive in sloughs; they usually feed on aquatic invertebrates. Submerged and floating plants grow here, such as bladderwort ("Utricularia"), waterlily ("Nymphaeaceae"), and spatterdock ("Nuphar lutea"). Major sloughs in the Everglades system include the Shark River Slough flowing out to Florida Bay, Lostmans River Slough bordering The Big Cypress, and Taylor Slough in the eastern Everglades.
