A large variety of animals live in estuaries, including different species of fish and birds. Estuaries are defined as the mouth of the river where the river's tide meets a stream.
Estuaries are an important part of the ecosystem due to the amount of organic matter they produce on a continuous basis. Due to the different habitats that make up a estuary, the environment supports a wide range of animal and plant life. Along with birds and fish, estuaries are home to other aquatic creatures such as turtles and rays. The land that surrounds estuaries supports a variety of insects and reptiles depending on the exact features it contains. For instance, a mangrove forest surrounding a estuary is home to large array of lizards, spiders and caterpillars.
Estuaries provide an abundance of resources and are important for fisheries and commercial fishermen. They are also popular tourist attractions and recreational outlets due to their beauty, unique features and water availability. Estuaries are also commonly used as transportation routes for shipping products to different parts of the world.
According to the United States Environmental Protection Agency, the human population of areas around estuaries is continuously growing which can have a detrimental impact on the organisms that inhabit the waterways.
