As a soft coral, it does not produce a hard shell of calcium carbonate. However, the Venus sea fan coral can hold itself upright in the current, growing to a height of about 6.6 ft (2 m) with relative ease. They are usually found in the western hemisphere, particularly near Bermuda, the Bahamas, and other parts of the Caribbean. Zooxanthellae...What's That?". NOAA Ocean Service Education.

While most people think of medicine as something that’s artificially created in a lab somewhere, most medicine is actually derived from natural compounds. One of the more common corals of the Atlantic Ocean and the Caribbean, lettuce coral is, as you might’ve guessed, a type of coral with a distinctive lettuce-like appearance. The polyps of stony corals have six-fold symmetry. In stony corals, the tentacles are cylindrical and taper to a point, but in soft corals they are pinnate with side branches known as pinnules. In some tropical species, these are reduced to mere stubs and in some, they are fused to give a paddle-like appearance. [26]
Corals are shallow, colonial organisms that integrate oxygen and trace elements into their skeletal aragonite ( polymorph of calcite) crystalline structures as they grow. Geochemical anomalies within the crystalline structures of corals represent functions of temperature, salinity and oxygen isotopic composition. Such geochemical analysis can help with climate modeling. [119] The ratio of oxygen-18 to oxygen-16 (δ 18O), for example, is a proxy for temperature. One of the smaller species of coral in our list, the clubbed finger coral is found in the Caribbean and in some parts of western Africa.

Chemicals in sunscreen used to combat sunburns are now known to be harmful to corals. Even the small amount that washes off of swimmers' skin can cause a reef damage, especially in areas that are popular for swimming or diving. These corals are naturally found in a wide range of different locations in the Indo-Pacific oceans, though they tend to prefer sandy and muddy seafloors. In particular, they are mostly found from New Caledonia to the Red Sea and they prefer water that’s less than 130 ft (40 m) deep.

Corals predominantly reproduce sexually. About 25% of hermatypic corals (reef-building stony corals) form single-sex ( gonochoristic) colonies, while the rest are hermaphroditic. [ citation needed] It is estimated more than 67% of coral are simultaneous hermaphrodites. [42] Broadcasters [ edit ] External videos
Whether you’re a keen scuba diver or simply an ocean lover, chances are pretty high that you’ve marveled at the wonders of the world’s colorful coral reefs at some point in your life.
Coral Blue Plaid Pattern
Coral blue works well with several different colors. For a more feminine space, pair coral blue with peach, soft pink, muted green and pale yellow. Incorporate accents in deep brown to soften out the colors and create a sense of cohesion. You can use hues in the same family but more saturated versions of each to create a space that brings to mind the sea, the sunset or the sunset at sea. Coral is also a source of natural compounds used in medical treatments, making it an important resource for human health. A popular source of coral material for jewelry and other manufactured goods, precious coral refers to the species within the genus Corallium.
Leaf corals are widely distributed throughout the Indo-Pacific, however, relatively little is known about its overall population. Most leaf corals live no further than about 50 ft (15 m) in depth and they prefer to live on sloping surfaces. W. W. Toller; R. Rowan; N. Knowlton (2001).

Most commonly known as the boulder star coral, this species of coral is found in the western Atlantic, particularly around the Caribbean. It is one of the more abundant reef-building corals within its range and it can be found throughout the region down to a depth of about 260 ft (80 m). Fancy yourself as a veritable coral expert?

Squires, D.F. (1959). "Deep sea corals collected by the Lamont Geological Observatory. 1. Atlantic corals" (PDF). American Museum Novitates (1965): 23. To assess the threat level of coral, scientists developed a coral imbalance ratio, Log (Average abundance of disease-associated taxa / Average abundance of healthy associated taxa). The lower the ratio the healthier the microbial community is. This ratio was developed after the microbial mucus of coral was collected and studied.

Presently, corals are classified as species of animals within the sub-classes Hexacorallia and Octocorallia of the class Anthozoa in the phylum Cnidaria. [8] Hexacorallia includes the stony corals and these groups have polyps that generally have a 6-fold symmetry. Octocorallia includes blue coral and soft corals and species of Octocorallia have polyps with an eightfold symmetry, each polyp having eight tentacles and eight mesenteries. The group of corals is paraphyletic because the sea anemones are also in the sub-class Hexacorallia. Corals have multiple reproductive strategies – they can be male or female or both, and can reproduce either asexually or sexually. Asexual reproduction is important for increasing the size of the colony, and sexual reproduction increases genetic diversity and starts new colonies that can be far from the parents.
