Residents such as lobster, eel, and tropical fish can be seen around the ship's rotting timbers. Excellent areas for bay snorkeling are south of Billy's Point and east of Long Arsenicker Key. The water is clear and the currents are very manageable. Wading Birds and Waterfowl Biscayne National Park is a sanctuary for birds. They are drawn to the bay year-round, as each follows its own instincts for survival.
Brown pelicans patrol the surface of the bay, diving to catch their prey.
White ibis meander across exposed mudflats, probing for small fish and crustaceans. Large colonies of little blue herons, snowy egrets, and other wading birds nest seasonally in the protected refuge of the Arsenicker Keys. The extremely shallow waters surrounding these mangrove islands in the south bay are especially well suited for foraging. Any place along the mangrove harbors offer excellent bird-watching. You can see numerous species of wading birds, including eight that nest within the park.
