Life in the estuary is always changing. Ocean tides of salt water flow in and out of the estuary and mix with the fresh water that flows from rivers and streams. The animals that swim or wade in the waters or make the mudflats their homes must have physical or social adaptations that allow them to live in the salty mix. Discover how and why animals survive and thrive in these sheltered biomes!

This nonfiction book explores the wildlife found in brackish estuary biomes--part of the Fauna del bioma series.
