Sea Fans (Gorgonians)

Sea Fans are magnificent sea life creatures that enhance the beauty of the sea. They live deep inside the sea or underwater that exhibits a special place in the world's ocean. However, Sea fan corals are equally similar to soft corals that are most wide-spread underwater. They are also known as Gorgonians with the scientific name Alcyonacea. Sea Fan dwells in the tropics and subtropics region of the sea. However, these are kinds of corals that do not exhibit calcium carbonate skeletons. Therefore, if you love sea life, you have to love sea fans of sea life to a great extent. However, the specialty of sea fans corals that they hold themselves tightly in the sea mud or sand rather than on any sea's rigid substrates.

In some cases, few sea fan corals take about 8 inches of sand underwater to hold themselves up. In addition to this, sea fan corals are sometimes nocturnal that extends their polyps, especially at night. They are also known as night-time predators. For example, cardinalfish and squirrelfish are predators that only come out during night time and hide in the daytime. 

Features of Sea Fans 

Sea fan corals have large polyps and are not always fan-shaped. They can be like a bottle brush that exhibits in different direction underwater. They are also a wide-spread creature that lives or dwells throughout the world's sea. 

Sea fans or corals mostly live or dwell on shallow water, especially in the sea's tropics and subtropics region. 

They live in great covering larger areas holding prominent areas along with sea walls. They live, especially in the Caribbean Sea. Underwater you might discover a forest of sea fans that looks magnificent and mesmerizing when you opt for scuba diving or a glass-bottom boat ride. 

Gorgonians come in different forms, such as Venus fans, sea whips, and sea fans in large numbers. 

Gorgonians corals are widely different from other sea life as they consist of a considerable number of tentacles. 

Sea Fan coral does not live in single. However, they live in cluster form spreading in all directions from a central axis. It is wise to say Gorgonians highly occupy the Caribbean. Also, the sea fan consists of a cluster of small coral polyps. 

The sea where it has flow-rich area gorgonians dwells there.

The sea fans consist of tiny polyps that come in millimeters in size, comprising delicate branches going in all directions. The specialty of the polyps that they form nutrients by connecting tissue. 

When the sea is undergoing current, they allow their inbuilt fan to spread or open up along with the current. The fan shape of the sea fans largely depends on the place they mostly dwell upon. However, the sea where it is calm and extensive the sea fans extent into thinner, rigid, and taller. 

The sea fans consist of tiny polyp that makes up an ocean fan with numerous stinging tentacles. During the night time, every polyp spreads out these arms to get tiny fish. This, combined with the fans' spread shape, implies these magnificent underwater creatures viably turns into sea predators, capturing its prey as they move through on the current.

The submerged world is brimming with colorful ocean fans who are no exemption. They form various tones of great colors of purple, pink, red, yellow, orange, or even white. They get their brilliant tones of colors from the algae that carry on within every coral polyp's tissue. There can be more than 1,000,000 algae for every square centimeter of coral polyp tissue. Just as giving the fan their incredible colors, these photosynthesizing sea creatures use daylight and waste-products from the polyp to create oxygen and overabundance supplements, which the polyps can utilize.

Sea Fan Care

Sea fan anchor themselves in mud or sand instead of attaching themselves to hard substrates. Some Sea Fans require up to 8 inches of sand. Most Sea Fan Care are nocturnal, only extending their polyps during the nighttime hours. They consume plankton and require strong currents to carry their food.

Sea Fan Care, Moderate to strong water flow helps some shed a thin membrane layer, much like leather corals, every few days to help rid their tissue of bacteria, algae and other irritants. Sufficient water flow helps blow off the mucus membrane ensuring better overall health and longer polyp extension. Sea fan care always prefer to be placed upright, standing tall, secured to a rock with marine epoxy. If they are leaning up against the aquarium wall or against another hard surface, it impedes the water flow and harms the tissue. Gorgonian Sea Fan Care. Gorgonians are often associated with the vision of graceful sea fans on the floor of the Caribbean.

Types of Sea Fan Corals

Bottle Brush Sea fan corals are not always meant to be fan-shaped. They are quite similar to bottle brush, branch in various headings from a central axis. Bottle brushes will have little polyps, while different types of delicate corals and ocean fans will have a lot bigger polyps. Bubblegum coral, for instance, growing up to 20 feet tall, appears to be unique than bottle brushes. Regularly pink, bubblegum corals are shrouded in knobs that look like chunks of bubblegum. Ocean fans are also exceptional among corals in that they plant themselves in sea mud or sandy bottoms rather than rigid substrate like most types of coral need to build up.

Bamboo Coral Sea Fans

Bamboo corals have a unique structure: they have a joint skeleton. Polyps develop on calcareous bits of the skeleton, which are separated by protein hubs. Found as profound as 15,000 feet, bamboo coral is cosmopolitan - occupying various seas at various profundities. Bamboo corals skeleton is also being discovered for use in bone transferring for people.

Ship Whips Sea Fans

Ship Whips or Ocean whips are a gathering of corals portrayed by long, whip-like branches, brilliantly colored. The polyps of ocean whips develop on top of one another and are given structure; however, the spicules inside the polyps' tissue. Ocean whips have somewhere in the range of one a couple of branches, up to many branches.

Multi color Sea Fans

Multicolor sea fans come in varied colors and varied forms. They are also a type of sea fan that comprises a cylindrical-shaped fan in bushy and tiny structures. The cylindrical branches go up to 30 cm tall that grows in colony or cluster form. They are also often joined or intertwine together. They come in multicolor, exhibiting a beautiful landscape underwater. They come in a wide range of colors ranging from yellow, red, pink, and white, spreading in all directions. They are often found in parts of South Africa 10-30 m underwater.

Blueberry Gorgonian Sea Fan

Blueberry Gorgonian is also known as the blue tree coral, which is widely famous and popular underwater. As the name suggests, this coral comes in blue color, a great showpiece of water life. They are positively peaceful and can be a great centerpiece of a reef aquarium. They require stronger water-flow and supplemental feeding numerous times every week. This blue tree coral feed on baby shrimp, micro-plankton, and others.

Purple Bush Gorgonian Sea Fan

The purple bush gorgonian is widely famous underwater. They come with long branches purple in color that exhibits feather-like colonies. They come with a maximum height of 12 inches approximately. However, they are commonly found in the Caribbean. They are made of tall colonies with point-up round branches. Therefore, they exhibit feather-like branches extending in all direction underwater. Also, their pointed branches come in a thicker form.

Gorgonia Vent Alina Sea Fan

This Sea Fan coral can be commonly found in the walls of reefs in the form of patches. The regions of the reefs ordinarily up to 30 meters underwater. They will also flourish in regions where the water stream is at a steady speed. Gorgonia vent alina is an invertebrate marine animal that dwells in salty water. However, they can be recognized by their purple tissue and fan shape structure or form. The speed of the water is significant because of the way that all ocean fans are filter feeders. Filter feeders are creatures (naturally spineless creatures) that rely upon the progression of water to carry significant natural materials and supplements to the creature to utilize development and breath.

Reproduction of Sea Fan Corals

The reproduction system of the ocean fan is highly intriguing. The Common Sea Fan (like other delicate corals) is sexually very active and is proficient for accomplishing results in several ways. Most ocean fans reproduce by hatching vast amounts of eggs and sperm into the water. Since the sperm and eggs are released into the water and are not ensured by the mother or father, there is an incredible chance that the young can be circulated a long way from the parents and establishing new colonies of ocean fans. Therefore, the sea fans coral are capable of delivering both eggs and sperms at the very same time. This means they are highly fertile, both internally and externally.


Essentially all gorgonians make them think in like manner. They are exceptionally delicate. A light touch can cost the gorgonian their arms or tentacles. Additionally, too tall specimens can be handily removed from the ground by a supported driver in terms of their weight, which would mean this specimen's demise. However, not just clumsy driver or trophy hunters are among the foes of the gorgonian coral. These lovely and extraordinary creatures are exceptionally subject to a picturesque environment. The steady increase of the water temperature or the ocean's pollution may decrease the number of these delicate sea creatures to a great extent. Therefore, sea fan corals are a beautiful and magnificent creature that brightens the world of sea with its colorful tones, pattern, and structure.
