What is the difference between elkhorn and staghorn coral?
What is the difference between elkhorn and staghorn coral?
Elkhorn coral is the largest acroporid coral. It has brown to tan branches that spread like flat fans with white on the outer growing margins. Staghorn is quite different, golden yellow to medium brown, and again with white edges, but its form is a thicket of branching rods of up to 5 cm (2 inches) in diameter.

What does staghorn coral look like?
Colors range from dark gray and brown to more vibrant pinks, purples, and blues. Acropora muricata was formerly known as Acropora formosa. It should also be noted that there are other species commonly referred to as “staghorn coral,” including Acropora cervicornis, which is native to Florida and the Caribbean.
What animals eat staghorn coral?
Are Staghorn Corals preyed upon? Staghorn Corals are fed on by nudibranchs and are also prey for butterflyfish, which target polyps as well as worms and other small invertebrates. It’s also not uncommon for certain species of fish, such as parrotfish, to bite off parts of the coral to reach prey hiding within.
Is elkhorn coral hard or soft coral?
There are two main types of corals: hard corals and soft corals. Hard corals, like elkhorn coral and staghorn coral, grow in colonies and are often referred to as “reef-building corals.” Hard corals create skeletons out of calcium carbonate, a hard substance that eventually becomes rock.
How fast do elkhorn coral grow?
about 2 to 4 inches per year
Like staghorn coral, elkhorn coral has been listed as federally threatened under the Endangered Species Act. Colonies of elkhorn coral are relatively fast growing, with branch length increasing about 2 to 4 inches per year. Colonies reach maximum size in about 10 to 12 years.
How long does elkhorn coral live?
Elkhorn coral colonies live for centuries. These colonies grow 5-10 cm (2-4 inches) each year, reaching maximum size in 10 to 12 years.
Why is staghorn coral so important?
Due to their bush-like growth form, staghorn corals provide complex habitat for fish and other coral reef organisms. When staghorn corals are abundant, they provide shoreline protections from large waves and storms.
How big do staghorn corals get?
Like its name suggests, staghorn coral is a species of coral that looks a bit like the antlers of a male deer. Capable of growing into thickets up to five feet high and more than 30 feet across, staghorn corals produce long, cylindrical branches out of bases anchored to the ocean floor.
Why are staghorn corals are so vulnerable?
Staghorn Coral is listed as Critically Endangered on The IUCN Red List of Threatened Species. Climate change and the associated rise in sea temperature is the biggest threat to Staghorn Corals as changes in temperature can cause bleaching – when corals expel their zooxanthellae into the water column.
Does staghorn coral eat algae?
What do Staghorn Corals eat? Like many corals, Staghorn Corals have a symbiotic relationship with single-celled algae called zooxanthellae, which live in the polyp tissues. They produce nutrients through photosynthesis which they then pass to the corals.
What eats the staghorn coral?
Staghorn Corals are fed on by nudibranchs and are also prey for butterflyfish, which target polyps as well as worms and other small invertebrates. It’s also not uncommon for certain species of fish, such as parrotfish, to bite off parts of the coral to reach prey hiding within.
How fast does staghorn coral grow?
It is the fastest growing species of coral in western Atlantic waters, growing at a rate of four to eight inches (10.2-20.3 centimeters) every year (National Park Service, n.d.).

Why do we need staghorn coral?
Where are Elkhorn and staghorn corals found?
Both species are found in the Caribbean Sea and the Gulf of Mexico. In general, branching corals (to which Elkhorn and Staghorn belong), are found in all coral reef areas. Coral reefs are important ocean habitats and are home to around a quarter of all marine species, making them one of the most biodiverse habitats in the world.
Why are Elkhorn corals important?
When elkhorn corals are abundant, they provide shoreline protection from large waves and storms. Elkhorn coral is found typically in clear, shallow water (1 to 15 feet) on coral reefs throughout the Bahamas, Florida, and the Caribbean.
What is wrong with the staghorn coral?
In the early 1980s, a severe disease event caused major mortality throughout its range and now the population is less than 3 percent of its former abundance. The greatest threat to staghorn coral is ocean warming, which causes the corals to release the algae that live in their tissue and provide them food, usually causing death.
Is elkhorn coral a hermaphrodite?
Elkhorn coral is a simultaneous hermaphrodite, meaning each colony produces both eggs and sperm, but usually does not self-fertilize. Elkhorn coral sexually reproduces once per year after the full moon in late summer by “broadcast spawning” eggs and sperm into the water column.
