What causes branching corals?

What causes branching corals?

Coral reefs begin to form when free-swimming coral larvae attach to submerged rocks or other hard surfaces along the edges of islands or continents. If a fringing reef forms around a volcanic island that sinks completely below sea level while the coral continues to grow upward, an atoll forms.

What are coral branches called?

Branching corals (also called arborescent, arboreal or ramose corals) branch like a tree. They grow from a base or trunk and their branches have projections of their own. Branching corals are very diverse but generally the term branching describes colonies that have secondary branches coming off the first branch.

What is Foliaceous coral?

Foliose corals have a coral growth-form that is highly variable. Foliaceous corals form horizontally flattened, unifacial plates or lobes that are attached to the reef substrate from the basal (ventral) surface. The plates may form tiers, whorls or vases, which can stacked in a complex, multi-layered arrangement.

What is Digitate coral?

Digitate corals: this category of corals resembles fingers or large clumps of cigars, that have no other branches. They grow vertically and are generally not as common as most other types of corals. Mushroom corals: as their name would suggest, these resemble the cup of a mushroom.

Where are branching coral found?

The branch coral (Acropora florida) is a species of acroporid coral found in the southwest and northern Indian Ocean, the central Indo-Pacific, Australia, Southeast Asia, Japan and the East China Sea, Cook Islands and the oceanic west Pacific Ocean.

How is a barrier reef formed?

Coral reefs form when pre-existing reefs release a burst of larva into the water. The larva will drift until they hit a hard surface such as submerged rocks, or edges of islands. As the coral develops, it takes the form of one of the three main reef structures; fringing, barrier or atoll.

Where are branching corals found?

What is an individual coral called?

Almost all corals are colonial organisms. This means that they are composed of hundreds to hundreds of thousands of individual animals, called polyps. Each polyp has a stomach that opens at only one end.

What are polyps coral reef?

Coral reefs are built by and made up of thousands of tiny animals—coral “polyps”—that are related to anemones and jellyfish. The polyp uses calcium and carbonate ions from seawater to build itself a hard, cup-shaped skeleton made of calcium carbonate (limestone).

What is free living coral?

The free-living Heterocyathus and Heteropsammia corals include two species that are commonly called walking corals. These corals are able to move across the sand at lightning speed (for a coral, anyways), covering a few meters of territory in a day.

What are 5 types of coral?

Are LPS corals hard to keep?

Much information says that hard corals are more difficult to keep in a reef tank than soft corals — and, of the hard corals, LPS are easier to keep or less difficult than SPS. Of the hard corals LPS are next, with species like Bubble corals, Plerogyra spp., being hardier than others.

What kind of coral has smooth branch tips?

Seriatopora is a small, branching coral that has fuzzy polyps. The branches can have smooth branch tips or pointed branch tips. Identify this coral by looking at the placement of each polyp: in Seriatopora coral, all the polyps line up in a neat row or series.

What kind of coral looks like fish eggs?

Overview. The Frogspawn Coral is a large polyp stony coral (LPS) often referred to as the Wall, Octopus, Grape, or Honey Coral. Its polyps remain visible throughout both the day and night, resembling a mass of fish eggs or frog eggs, hence one of its common names Frogspawn. Its coloration is green or brown to tan in color.

Are there branching corals in the Indo Pacific?

Corals grow in several unique forms, but none are more recognizable than branching species. Here’s our introduction to the branching corals of the Indo-Pacific. Corals grow in several unique forms, but none are more recognizable than branching species.

How can you tell if a Montipora coral is branching?

Montipora can be branching, encrusting, or form thin plates. At times you can even find branches going out of plates. You can identify Montipora via its small corallites, which are embedded in the surface of the coral. You’ll often find them between ridges, although they lack a distinct corallite wall.
