The coastal waters of Nassau and Duval county are host to a wide range of habitats, both in the water and on land. Aquatic grasses, saltmarsh, mud flats, and oysters are four habitats that are important to animals within Nassau and Duval county's waters. Aquatic grasses, both fresh and salt water, provide shelter for many small fish, crabs, and worms. They also help stabilize shifting sands on the bottom of the St. Johns and other coastal rivers and improve water clarity by trapping fine sediments and particles. Salt marshes provide habitat for small fish and crabs and help protect the shoreline from wave action. Mud flats are home to clams, crabs, and burrowing worms, which serve as food for many wading birds and fish. Lastly, oysters, located mostly near rivers, are a popular habitat for sport fish that feed on crustaceans or small fish.

Additional information about these habitats can be found under Native Habitats.

With its wide ranging habitats, the coast waters of Nassau and Duval counties are also home to wide variety of animals. These animals can range in size from a fraction of an inch-long (many invertebrates and small fish), to weighing 50 tons (100,000 pounds) and 55 feet in length (the North Atlantic right whale). Some of the area's animals are unusual, like the batfish or horseshoe crab. Most live here year-round, while others briefly stop by (white pelican). Residents and visitors to the area will often stop and spend some time watching a wading bird chase fish along a shoreline or a dolphin swim by. There is always something to see in Nassau and Duval counties.

Animals of the Coast provides information about a few of coast's residents: birds of the coast, North Atlantic right whale, sea turtles, and Florida manatee.
