This richness and uniqueness make the reef …The most important group within Phylum Cnidaria are the corals. Corals are multicellular animals that have a similar life habit to sea anemones. They are anchored to the ocean floor and precipitate a mineral framework around themselves which raises them up off the sea floor to more efficiently collect food. Each coral animal is known as a polyp. Petoskey stones are a fossil rock made from the coral Hexagonaria percarinata. It is thought that these corals lived during a time before the dinosaurs, when the Lake Huron area was covered by sea. The stone itself is covered in six-sided coralites that are enhanced when wet or polished. When dry, however, the stone resembles limestone.
