Anna Maria Island, sometimes called Anna Maria Key, is a barrier island on the coast of Manatee County. It was originally discovered by the local Timucan and Caloosan American Indian tribes. Tampa Mayor Madison Post named the island for his sister-in-law Anna and his wife Maria. Anna Maria is home to plenty of wildlife, especially in its waters. Not only does it draw locals and tourists, but it brings scholars to its shores to study and protect the marine life.
