Lace Coral

P. damicornis is a colonial coral and can grow into clumps up to 30 cm (12 in) high. It is distinguishable from other members of the genus by the verrucae (wart-like growths) on its surface being more irregularly arranged. It is more branched than the otherwise similar P. verrucosa. Its form varies according to its habitat and is more open and branched in calm positions and more compact on the upper parts of reefs where water movement is greater. Its colour varies and may be greenish, pink, yellowish-brown or pale brown.

Cauliflower coral is native to the tropical and subtropical parts of the Indian and Pacific Oceans. Its wide range extends from East Africa and the Red Sea to Japan, Indonesia, Australia, Hawaii, Easter Island, and the western coast of Central America. It is found at depths to about 40 m (131 ft), but is most common between 5 and 20 m (16 and 66 ft), often forming dense patches. It is equally found on reef slopes and in lagoons, among mangroves and on wharves, but not in areas with strong water movement. With such a wide range, it is one of the most abundant of corals.

In general, coral reefs around the world are being destroyed and although this coral is common and relatively resilient, populations likely are in decline along with their habitat. This coral is collected for the aquarium trade and in some regions, it is mined for conversion into cement. The IUCN has listed it as being endangered, as it susceptible to reef degradation. Like all corals, it is listed on CITES Appendix II.
