In the past, soft corals were thought to be unable to lay new foundations for future corals, but recent findings suggest that colonies of the leather-coral genus Sinularia are able to cement sclerites and consolidate them at their base into alcyonarian spiculite, [10] thus making them reef builders.
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.
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]
Variable soft corals grow in small colonies of up to 7 cm. They are mushroom-shaped, having a short stalk with a round head covered with feeding polyps. The stalk is of variable height and may also be absent. The colour is extremely variable and may be red, purple, orange, white, yellow or pink and often varies between the colony and the polyps.
Cladiella is a genus of soft corals native to the Indo-Pacific region. These corals are commonly known as colt corals or finger leather corals and are often kept in reef aquaria. They grow fast, have short rounded or conical lobes and are sticky to the touch owing to the production of much mucus. They are creamy or pale grey in colour.
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 ...
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]
