Swamp swimmers are two of the most common animals found in wetlands, such as swamps, marshes, and bogs. The two animals are crocs (5 letters) and gators (6 letters). Crocs are large reptiles with long snouts and powerful jaws, while gators are similar to crocs but have shorter, broader snouts. Both animals are well adapted to their wetland habitats, and can be found in many parts of the world.
