Just under 3% of Texas' land area is covered in surface water, but don't let that fool you. Texas' waterways are full of life - from fish, to salamanders, to turtles and sharks, and even humans. In the spring and summer, you can find Texans passing the time on our state's waterways through activities like fishing, swimming, kayaking, and photography. Texas has many different waterways like streams and rivers, swamps and marshes, bayous and lakes, and even the deep open water of the Gulf of Mexico. No matter how big or small, each water body has different features and characteristics that make up an ecosystem for different plants and wildlife. The critters that live in these waters have certain adaptations that allow them to survive in their environments.
