It is found in the Indo-Pacific Ocean. In its specific name Christian Gottfried Ehrenberg honoured his late partner the Prussian naturalist Wilhelm Hemprich; they were among the first to study the marine life of the Red Sea. DescriptionLobophyllia hemprichii is a colonial species of coral that may form hemispherical or flattened mounds up to {{convert|5|m|0|abbr=on}} in diameter. Several adjacent colonies, sometimes of different colours, may grow together to form a composite colony.[4] The corralites (skeletal cups) may be phaceloid (having a tubular form and growing from a common base) or flabello-meandroid (arranged in valleys with the neighbouring valleys each having a ridge, with the valleys dividing irregularly). Each corallite has a number of septa (vertical blades inside the corallite cup) which taper in thickness and have tall sharp teeth. This coral is some shade of grey, pink, violet or yellowish-brown, sometimes a uniform colour or sometimes with contrasting regions. L. hemprichii is a zooxanthellate coral, having single-celled photosynthesizing organisms known as dinoflagellates living within the tissues. Photosynthesis of these protists provides the coral with nutrients. The thick, fleshy polyps can retract back into the corallite cups in which they sit or extend their tentacles to feed.[3]DistributionLobophyllia hemprichii is native to the tropical and subtropical Indo-Pacific. Its range extends from the Red Sea, the Gulf of Aden and the east coast of Africa through the Indian Ocean and the Bay of Bengal to Japan, Indonesia, New Guinea and Australia. It is most common at depths between {{convert|9|and|15|m|0|abbr=on}} but can occur down to about {{convert|50|m|0|abbr=on}}.[1] It is found on upper reef slopes, where it is often the dominant species of coral and sometimes the only species.[3]StatusThe International Union for Conservation of Nature lists this species as being of "least concern", on the basis that it has a wide range and is common in most of that range. Although susceptible to bleaching and to other damage caused to corals by a rise in sea temperature and ocean acidification, it is thought to be more resilient than many other species because of its large population size and wide genetic variability. It is collected for the aquarium trade, Indonesia being the main exporter. It is included in CITES Appendix II as are all stony corals.[1] References1. ^1 2 {{Cite journal | author = Turak, E. | author2 = Sheppard, C. | author3 = Wood, E. | title = Lobophyllia hemprichii | journal = The IUCN Red List of Threatened Species | volume = 2014 | page = e.T133419A54257594 | publisher = IUCN | date = 2014 | url = http://www.iucnredlist.org/details/133419/0 | doi = 10.2305/IUCN.UK.2014-1.RLTS.T133419A54257594.en | access-date = 10 January 2018}} {{Taxonbar|from=Q1867091}}2. ^1 {{cite WoRMS | author=Hoeksema, Bert |year=2018 |title=Lobophyllia hemprichii (Ehrenberg, 1834) |id=207392 |accessdate= 2018-07-31}} 3. ^1 2 {{cite web |url=http://coral.aims.gov.au/factsheet.jsp?speciesCode=0236 |title=Lobophyllia hemprichii |year=2013 |work=Coral Fact Sheets |publisher= Australian Institute of Marine Science |accessdate=2015-01-02}} 12 : Lobophylliidae|Cnidarians of the Indian Ocean|Cnidarians of the Pacific Ocean|Fauna of the Red Sea|Marine fauna of Africa|Marine fauna of Asia|Marine fauna of Oceania|Marine fauna of Southeast Asia|Marine fauna of Western Asia|Anthozoa of Australia|Corals described in 1834|Taxa named by Christian Gottfried Ehrenberg |
