In geographic ranges, it is found in the southeastern part of the of the nearctic region and the northwestern part of the neotropical region. Colin, ; Kester, ; Sterrer, Most nerve cells allow impulses to travel in either direction. In other words, Central and South America. Recently, mortality has also been attributed to tumor growth.
The skeleton of G. This coral is sometimes attacked by the fungus Aspergillus sydowii which causes aspergillosis. As the polyp grows upward, the base’s ventalna also turns upward, forming a cup called the epitheca, which contains daily growth bands.
This needs close -up observation to distinguish; otherwise, the presence of side growths on G.
Gorgonia ventalina, Common Sea Fan
Common sea fan Gorgonia bentalina Linnaeus, Description: There have been studies into the role that sea fans, including G. Marine Invertebrates of Bermuda. Because they depend on symbiotic photosynthetic algae, zooxanthellae, they cannot live where light does not penetrate.
Brusca and Brusca, Gorgonia ventalina Linnaeus. They are often difficult to distinguish. These and other sturctures called septa form the skeletal boundaries found at the ventaljna of the coral goggonia, which are left behind as a result of the upward growth of the polyp.
ADW doesn’t cover all species in the world, nor does it include all the latest scientific information about organisms we describe. The main branches are often purple and the fan is orientated at right angles to the current. Photo 1 of The skeleton is composed of calcite and gorgonion, a collagen -like compound. The calyces in which the polyps are embedded are in two rows along the branches.
According to Cary, there is no evidence that gorgonian colonies ever die from gorgonua age. Many of the smaller branches are compressed in the plane of the fan, which distinguishes this species from the Venus sea fan Gorgonia flabellum.
Druffel, August 5, ; Gotelli, April The two large species of borgonia genus, G. These anti-predator defenses act as successful feeding deterrents to the Cyphoma gibbosuma common predator of the G.
Cary, May 15, ; Colin, It is found in the western Atlantic Ocean and the Caribbean Sea. The larvae typically spend several days as plankton before settling on a hard surface to begin formation of a colony. They form the basis for rich communities of other invertebrates, plants, fish, and protists.
The Alcyonaria as a factor in reef limestone formation. The spicules are small and fusiform. The cause of death is attributed to the lack of food and oxygen to the polyp. Since the color of the fan varies, the shape of the spicules is the only positive identifier of G.
Cyphoma gibbosum feeds on gorgonian polyps by crawling slowly over the skeleton. In Anthozoans, specialized sensory organs are absent and nerves are arranged in nerve nets.
Each polyp extends its eight tentacles to catch plankton drifting past on the current.
