Compare salt marshes with mangrove swamps

Mangrove swamps are coastal wetlands found in areas such as the Gulf of Mexico and the southern tip of Florida. They form in tropical and subtropical areas where salt water and fresh water meet. Salt marshes are usually composed of deep mud and peat. They can occur all over the world, but are more prevalent in middle to high latitude areas. They are coastal wetlands which are flooded by the salt water the tides bring in.
