Soft corals contain minute, spiny skeletal elements called sclerites, useful in species identification.Sclerites give these corals some degree of support and give their flesh a spiky, grainy texture that deters predators.
Nephtheidae is a family of soft corals in the phylum Cnidaria. Members of this family are known as carnation corals, tree corals or colt soft corals. They are very attractive and show a wide range of rich and pastel colours including reds, pinks, yellows and purples. They are popular with reef aquarium hobbyists. [2]
Octocorallia (also known as Alcyonaria) is a class of Anthozoa comprising over 3,000 species [1] of marine organisms formed of colonial polyps with 8-fold symmetry. It includes the blue coral, soft corals, sea pens, and gorgonians (sea fans and sea whips) within three orders: Alcyonacea, Helioporacea, and Pennatulacea. [2]
Dendronephthya hemprichi is a common soft coral found from Red Sea to Western Pacific.In may 2023 on the Mediterranean coast of Israel exactly on the coasts of the city of Sdot Yam many specimens were filmed, subsequently it was also photographed in Lebanon In Byblos.It is usually pink or orange with transparent trunk and it grows up to 70 cm. [1] [2] [3] It exists at 30° N latitude. [4]
Capnella are arborescent, some species are lobed. Generally they are grey with brown polyps. Colour intensity is dependent on light intensity, the higher the intensity of light, the lighter colour of the coral. They form thick trunks with branches that closely resemble trees. In stronger currents they form flatter colonies with shorter branches.
In the Red Sea, S. glaucum is one of the most prevalent soft corals of the family Alcyoniidae. [2] The Red Sea is the native home to 40% of the known 180 species of soft corals. [2] Soft corals like S. glaucum of the family Alcyonniidae do not have a hard exoskeleton. They are sedentary and taxonomically identified by calcareous sclerites on ...
Litophyton arboreum, also known as broccoli coral, is a common soft coral found from the Red Sea to the Western Pacific. It grows up to 80 cm, usually on seaward reef slopes or hard bottoms. The color of L. arboreum varies from pale olive-green to yellow or grey. L. arboreum are anthozoans in the order Alcyonacea in the family Nephtheidae.
The axis is made up of scleroprotein with non-spicular crystalline calcium carbonate arranged in concentric layers. Polyps of these types of corals are connected by a sheet of tissue called coenosarc. These polyps range in size from 1–3 mm in diameter. Soft coral is categorized by slow growth, late maturity, and longevity.
