Estuaries form where rivers containing freshwater flow into the salty waters of an ocean. The mixture of freshwater and salt water stays balanced as long as both the river and the ocean tides continue to mix at the river's mouth. Estuaries are usually calm and often contain many food sources. Because of this, many species of fish and other organisms breed and raise their offspring in estuaries. These organisms are adapted to life in brackish estuary waters.
