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 mud flats, 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.
Reefs are in fact host to the ocean's most spectacular galaxies of fish.
Along Biscayne's reefs more than 200 types of fish can be spotted. Each holds its own fascination for us. Some are impressive in size, others in color. Many behave in bizarre, unexplainable ways, at least to humans. Few places on earth can match the diversity of life that inhabits the reefs' underwater wilderness.
