What kingdom is Gorgonia Ventalina in?
What is the classification of a sea anemone?
Sea anemones and corals
Sea anemone, any member of the invertebrate order Actiniaria (class Anthozoa, phylum Cnidaria), soft-bodied, primarily sedentary marine animals resembling flowers.
What class do sea fans belong to?
Sea fan, (genus Gorgonia), any member of a genus of invertebrate marine animals of the suborder Holaxonia (class Anthozoa, phylum Cnidaria). It is a variety of coral composed of numerous polyps—cylindrical sessile (attached) forms—that grow together in a flat fanlike pattern.
What is the phylum of Meandrina?
Why Gorgonia is called sea fan?
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. Many of the smaller branches are compressed in the plane of the fan, which distinguishes this species from the Venus sea fan (Gorgonia flabellum).
What is the common name of Meandrina?
Meandrina meandrites, commonly known as maze coral, is a species of colonial stony coral in the family Meandrinidae.
How are cnidarians classified?
Cnidarians are classified into four main groups: non-moving (sessile) Anthozoa (sea anemones, corals, sea pens); Cubozoa (box jellies);swimming Scyphozoa (jellyfish); and Hydrozoa, a broad group that includes all the freshwater cnidarians as well as many marine forms. Cnidaria have no organs like hearts or lungs.
What is a group of anemones called?
Cnidaria – the nettle animals. Corals, sea anemones and jellyfish belong to a group of animals called cnidarians (pronounced ‘nid-air-e-ans’).
Is a sea fan living?
The basic shape of a Common Sea Fan is the common slender base that branches out to a single, flat plane layer. This allows living tissues to form a layer over the sea fan skeleton’s surface. More than a million microscopic alga called zooxanthellae are found in a square centimeter of coral tissue.

Is Meandrina a Coelenterate?
Description. Meandrina meandrites forms massive hemispherical heads or develops into substantial flat plates and can grow to nearly 1 metre (3 ft 3 in) in diameter.
What is the scientific name for brain coral?
Species Diploria labyrinthiformis Grooved brain coral.
How big does a Gorgonia ventalina flower get?
The spicules are small and fusiform. The polyps of the G. ventalina protrude from the spicules as tiny fragile white flowers. It is these individual polyps that form the sea fan. Gorgonia ventalina can be up to 180 cm tall and 150 cm wide, with anastomose branches, which form uniplanar, reticulate, fan-shaped colonies.
What kind of Defense does Gorgonia ventalina have?
Gorgonia ventalina contains secondary metabolites and calcified sclerites that act as anti-predator defenses. These anti-predator defenses act as successful feeding deterrents to the Cyphoma gibbosum, a common predator of the G. ventalina. Cyphoma gibbosum feeds on gorgonian polyps by crawling slowly over the skeleton.
How does a Gorgonia ventalina coral reproduce?
Gorgonian corals reproduce asexually by cloning or fragmentation, with external fertilization. The larvae typically spend several days as plankton before settling on a hard surface to begin formation of a colony. ( Druffel, August 5, 1997; Gotelli, April 1991) There are several potential causes of death for G. ventalina.
Can a gorgonian colony die from old age?
According to Cary, there is no evidence that gorgonian colonies ever die from old age. ( Cary, May 15, 1915; Morse, et al., 1977) Gorgonia ventalina will orient according so that the “fan” is perpendicular to the motion of the waves. This orientation only occurs in the adult sea fans.
