 Millepora alcicornis is found in the Caribbean Sea, the Gulf of Mexico, Florida, the Cape Verde Islands and along the coast of Central and South America as far south as Brazil. It has also been found in Bermuda, but the morphology at that location is so different from that in the rest of its range that it may be a distinct species. It grows at depths of up to 40 metres (130 ft) and is the only fire coral that often grows at depths greater than 10 metres (33 ft).
