First, there’s a stark difference between hard and soft coral. Inside the corals’ clear outer tissues live microscopic algae, which transform sunlight into sugars through Photosynthesis. Staghorn coral is a significant part of the Caribbean since they built the reefs in the area during the last 5,000 years. Soft corals also need plenty of light (5 watts of light per gallon), and also mineral supplementation, but significantly less than the hard corals. It occurs in back reef and fore reef environments from 0 to 30 m (0 to 98 ft) depth. Use features like bookmarks, note taking and highlighting while reading Staghorn Corals … Staghorn corals form various shapes, from staghorn or upright branches to flat, plate-like structures and round, mounded clumps. More spineless and fabulous animals. However, it makes recovery from disease or bleaching episodes (where entire colonies or even entire stands are killed) very difficult. The upper limit is defined by wave forces, and the lower limit is controlled by suspended sediments and light availability. It occurs in back reef and fore reef environments from 0 to 30 m (0 to 98 ft) depth. ... SPS corals: Staghorn coral, Table coral, Cluster, Bottlebrush, Acropora spp. Not only are these reef-building hard corals one of the fastest growing, they also provide a sheltered home to a vast array of marine animals. Inside the corals’ clear outer tissues live microscopic algae, which transform sunlight into sugars through Photosynthesis. The hosts help themselves to some of the sugars and gain some colour through the process. Common types of hard coral on the Reef include brain coral and staghorn coral. Learn hard and soft corals with free interactive flashcards. The BRT completed the status review March 3, 2005. ("dendrogyra cylindricus") grows up from the sea floor, but wi…. Examples are Brain and Staghorn coral. This coral occurs in the western Gulf of Mexico, but is absent from U.S. waters in the Gulf of Mexico, as well as Bermuda and the west coast of South America. Explore below to learn more about these animals. Best Corals for Reef Tanks It's a fast grower and an easy coral to propagate, which contributes to their predominating numbers in the ocean, but also means that it needs plenty of room in the reef aquarium. Noble Staghorn Coral Acropora nobilis. One way to tell the difference between soft corals and hard (stony) corals is that the polyps of hard corals have six tentacles, which are not feathery. Staghorn corals form various shapes, from staghorn or upright branches to flat, plate-like structures and round, mounded clumps. As is typical for stony corals, staghorn coral consists of tiny polypswhich secrete a hard skeleton and live together in a colony. Staghorn coral forms antler-like branches growing in tangled dense thickets. The polyps of soft corals have eight feathery tentacles, which is why they are also known as octocorals. As examples, some of the more prominent Caribbean species are called staghorn, elkhorn, finger, brain, pillar, star, plate and lettuce coral. Staghorn corals come in many shapes and sizes and can be highly variable in colour and form, even within the same species. Like its name suggests, staghorn coral is a species of coral that looks a bit like the antlers of a male deer. Staghorn corals are perhaps the best known and most easily recognised of all corals. The staghorn coral (Acropora cervicornis) is a branching, stony coral with cylindrical branches ranging from a few centimetres to over two metres in length and height. This means that when our coral reefs are flourishing then our oceans are in good condition which contributes to a healthy planet. Common types of hard coral on the Great Barrier Reef include brain coral and staghorn coral. Maze coral, Merulinidae: Platygyra, Raffles Lighthouse, February 1992.Most merulinids (previously Faviidae) are typically found growing in a boulder shape. Brain coral can live for 1,000 years and grows almost half an inch (1 cm) every year. The preponderance of asexual reproduction in this species raises the possibility that genetic diversity in the remnant populations may be very low. The upper limit is defined by wave forces, and the lower limit is controlled by suspended sediments and light availability. When the polyps are retracted, the skeleton has corallites that twist and turn throughout the colony, giving it a maze-like appearance. Maze coral, Merulinidae: Platygyra, Raffles Lighthouse, February 1992.Most merulinids (previously Faviidae) are typically found growing in a boulder shape. For the whole family known as staghorn corals, see, 10.2305/IUCN.UK.2008.RLTS.T133381A3716457.en, "Survivorship and growth in staghorn coral (Acropora cervicornis) outplanting projects in the Florida Keys National Marine Sanctuary", NOAA Fisheries Species Directory - Staghorn Coral (, Critical habitat under the Endangered Species Act, The Structure and Distribution of Coral Reefs, https://en.wikipedia.org/w/index.php?title=Staghorn_coral&oldid=984860698, IUCN Red List critically endangered species, Creative Commons Attribution-ShareAlike License, This page was last edited on 22 October 2020, at 15:08. If a piece falls off, it's able to reattach to the substrate and start a new colony. These uncertainties as to recruitment/recovery potential and genetic status are the bases for increased demographic concerns for this species. Staghorn coral is one of the most important corals in the Caribbean. Colours and colony formation can depend on the growing conditions of the coral, depth, clarity of water, currents, and so on. The remains of reef-building hard corals provide the foundation for coral reefs, making these corals, along with the help of algae that live inside the corals, the natural architects of coral reefs. The park is home to about 30 species of coral. They are fragile and easily broken, and thus are responsible for most coral cuts amongst reef walkers. Elkhorn coral is known to grow quickly with an average growth rate of 5 to 10 cm (2.0 to 3.9 in) per year.
