Elkhorn is an intricate, relatively thin branching coral with an army green background and white growth tips and highlights on the coral body. Unfortunately, it has recently suffered a similar fate and is also critically endangered. I want to see pics of it in a closed tank/system. Low genetic diversity makes coral populations more susceptible to being decimated by disease. We have already protected nearly 4 million square miles of ocean and innumerable sea life - but there is still more to be done. 9 Colonies of Elkhorn Coral (Acropora palmata). Coral is destroyed by white pox disease more quickly in late summer, when seawater is the warmest. Having said that, Acropora are one of the most difficult corals to keep. The elkhorn coral is named for the antler-like shape of its colonies. It, along with staghorn coral and star corals (boulder, lobed, and mountainous), built Caribbean coral reefs over the last 5,000 years. Species name: Acropora palmata. It was formerly one of the most common corals on reefs throughout its range. ELKHORN CORAL, ABACO BAHAMAS (DORIAN UPDATE) Elkhorn coral (Acropora palmata) is a widespread reef coral, an unmistakeable species with large branches that resemble elk antlers. Like most shallow-water corals, elkhorn corals have symbiotic algae living within their cells, providing the corals with excess energy that they make via photosynthesis (the use of sunlight to convert carbon dioxide into food/energy). to the colony. In the United States, the Center for Biological Diversity petitioned the National Marine Fisheries Service to put 83 species of coral on the Threatened and Endangered lists; as of 2015, 22 had been added as threatened—including reef-building Elkhorn coral (although the petition requested endangered status)—and three had been added as endangered. Elkhorn colonies typically grow in water depths of less than 20 feet but may be present down to a depth of about 65 feet. Bottlebrush corals: Bottlebrush acroporas have short side branches. Apparently they are thriving here Colonies of elkhorn coral are relatively fast growing, with branch length increasing about 2 to 4 inches per year. Elkhorn coral grows into thick, robust branches and is the most important reef-building species in the Caribbean. Elkhorn coral primarily reproduces asexually; however, they are capable of producing sexually. Present-day atmospheric CO 2 (pCO 2) levels are estimated at 387 ppm, 30% higher than the natural range over the last 650,000 y . Acropora are very sensitive to quick changes in water quality, lighting, and flow. 3. These colonies can reproduce both sexually and asexually, and they are hermaphroditic – each animal produces both eggs and sperm. Cluster corals: Clustering acropora grows in various sized clusters that resemble cauliflower and is sometimes bumpy. Relatives of the sea anemone and every bit as splashy, corals display hues ranging from brilliant orange and deep salmon to pale pink and subtle violet. Elkhorn corals used to form dense zones on Caribbean reefs that harbored many diverse creatures but since the 1980’s, 90-95% of these majestic creatures have been lost to disease and coral bleaching. Placement. A Colony of Elkhorn Coral (Acropora palmata) Grows on a Healthy Reef in The Caribbean Sea. Specimens of elkhorn coral living in water with excess carbon dioxide have been studied for fertilization rates, ability of larvae to settle on reef substrate (where they produce new corals), and subsequent growth and survival. These provide important habitat for other reef animals, especially fish. Fact: All animals and plants are given a species name based on a technical term in biological taxnomy. Today, it is very rare and is considered critically endangered by reef scientists. During just a few days surrounding full moons in the fall, elkhorn corals release bundles of eggs and sperm that float to the surface, break apart, and mix. These provide important habitat for other reef animals, especially fish. Its genus name, Trachyphyllia, comes from the Greek trachys (rough) plus phyllon (leaf) because it resembles a rough leaf lying on the sandy bed. Throughout its range, it has become more and more rare, and scientists now consider it to be critically endangered (very highly vulnerable to extinction). As this coral grows, it forms a gnarling form like a branch from a tree growing on the windward side of a mountain. White pox is wiping out the elkhorn coral. Elkhorn is an intricate, relatively thin branching coral with an army green background and white growth tips and highlights on the coral body. Elkhorn coral can form dense groups called thickets in very shallow water. Elkhorn Coral colonies have suffered heavily from a variety of threats, notably white-band disease, bleaching and sedimentation. Sperm do not fertilize eggs from the same colony, so several colonies release their gametes at the same time, in a process known as broadcast spawning. When a storm or some other disturbance breaks apart a colony, each piece is able to reattach to the reef surface and begin growing again. Elkhorn is an intricate, relatively thin branching coral with an army green background and white growth tips and highlights on the coral body. While a colony can persist for centuries, individual coral polyps usually live for 2 to 3 years. Colonies reach maximum size in about 10 to 12 years. The species name consists of two words and is based on Latin. http://ow.ly/HoEaH, Cephalopods, Crustaceans, & Other Shellfish, Fishing pressure can surge before marine reserves are created, new study finds, Ted Danson and Katharine McPhee Headline Oceana's SeaChange Summer Party, Oceana Celebrates Belize's Removal from UNESCO's Sites in Danger List, Fishery council safeguards 16,000 square miles off California, More than 362,000 Square Miles of Fragile Seafloor Habitats Protected from Destructive Bottom Trawling off U.S. Pacific Coast. Due to their tree-like growth form, elkhorn corals provide complex habitat for fish and other coral ree… Within four years after the white pox was found, the population of elkhorn coral in that reef had decreased by 82 percent. Many steps have been taken within the Dutch Caribbean to protect this and other valuable coral species. Unfortunately, some newer, relatively less-experienced aquarium-keepers have had trouble getting them to open up and accept foods. Types of Coral The following are some of the best known Acropora corals Temperament / Behavior: As with most SPS coral, for c ontinued good health, this coral will require the addition of calcium, strontium, and other trace elements to the water. Elkhorn coral produce hard antler-like structures composed of calcium carbonate. Although millions of eggs and sperm, called gametes, are released, few coral larvae survive to settle and grow into new colonies. Staghorn coral is one of the most important corals in the Caribbean. During asexual reproduction, or asexual fragmentation, branches of coral break off and attach to the ocean floor. Enter your Saltwater Aquarium Enter parameters for your Saltwater Aquarium to get compatibility information while browsing. Sun coral care. New colonies form when branches break off of a colony and reattach themselves to the substrate. The ORA Elkhorn produces very little to no polyp extension and generates a thick slime when bothered. White pox is wiping out the elkhorn coral. We have a wide variety of corals all grown in our facility. Elkhorn coral’s branches can increase in length as fast as 2-4 inches per year. It is a fast growing species and is one of the most important reef-building species in the Caribbean. The two corals are sometimes found interspersed together, though elkhorn coral lives in shallow water of 1 to 5 meters in depth, while staghorn coral lives in deeper water, of 5 to 20 meters. Once the most common coral in the Caribbean and known as the “giant redwoods of the reef,” today it is more common to see rubble fields made up of dead elkhorn coral and only a few isolated living colonies. Research continues today in an effort to understand why intestinal bacteria attack coral and how water temperature and other factors contribute to coral diseases. How to Take Care of Elkhorn Ferns. Nope, that is a nice Montipora hirsuta , not the critically endangered Acropora palmata (Elkhorn Coral) This is the coral I'm talking about. Not all plate corals grab your attention the way fancy ones can, but they’re still neat looking and easy to care for corals, nonetheless. more White pox is wiping out the elkhorn coral.

This shallow water coral is vital to the construction of Caribbean reefs and is known to live to over 7,000 years old. Oceana joined forces with Sailors for the Sea, an ocean conservation organization dedicated to educating and engaging the world’s boating community. The Blue/Green Black-axil Chromis is easy to care for, beautiful, and peaceful. Coral age can be determined by counting coral growth rings the same way that tree rings are counted to determine tree age. Bleaching occurs when seawater temperatures rise, triggering corals to expel the colorful algae cells that typically provide them with food. And the disease may be coming from people. Numerous species (including caribbean spiny lobsters, parrotfishes, tube blennies, and others) directly rely on elkhorn coral as their primary habitat. The newest line is designed from the most endangered coral in the world, Fused Elkhorn.
