Millepora

Fire corals (Millepora) are a genus of colonial marine organisms that exhibit physical characteristics similar to that of stony coral. While coral is in the name, fire corals are not true (stony) corals but are instead more closely related to Hydra and other hydrozoans, making them a part of the organism known as hydrocorals. Fire Corals make up the only genus in the monotypic family Milleporidae.
