Scientific Name: Briareum sp (used to be classified as Clavularia viridis) Common Name: Star Polyps. This article will provide an overview of zooxanthellae biology, and how these dinoflagellates are isolated for scientific study. Biology [bi-ol-uh-jee] A natural science concerned with the study of life and living organisms. Scientific Name: Zoanthidae Common Name: Zoa Type of Coral: Soft Coral Lighting: middle to high Placement : middle to top Flow: Moderate to high Care Level: moderate Temperament: Gentle Feeding : Zooplanton , Phytoplankton Premium Coral food and Rotifer Approximate Size : S : 1-2 inch M : 2-3 ; L >3 to 4 inch on live rock Cold-water Corals [kohld–wah-tur kohr-ls] The polyp is related to the anemone, and consists of a stomach with a mouth at one end. There are occasional coral species whose polyps don't fit the norm of their group, being too large or too small. To improve our understanding of zooxanthellae biology, scientists isolate these symbionts from the coral host under a variety of environmental conditions. Cnidarian species are found throughout the world and are quite diverse, but they share many similar characteristics. Large Polyp Branching Corals Euphyllia. A group of the Great Star corals may form a dome like shape when each species cluster together. Polyps are colonial corals, and most of them are extremely hardy, making them ideal candidates for the beginner reef aquarist. The term 'soft coral' is the name given to the coral group with the scientific name of Alcyonacea. Classification: Though a coral polyp looks like a plant, it’s really an animal, or rather, a colony of animals, and is classified into the Phylum Cnidaria (also called Phylum Coelenterata). The taxonomy of the Zoanthids has been very difficult and though some species are described, it is still largely speculative. The upper, or free, end of the body, which is hollow and cylindrical, typically Most corals are colonies of thousands of polyps (clones) which form the familiar "coral head". photo by … Most living stony corals are yellowish, brownish, or olive, depending on the colour of the algae living on the coral. Image: Dr. Paul Muir, QM. Coral polyps are at the basis of the coral reef food web, different types of polyps living in symbiotic relationships or just providing shelter for various species of marine creatures. About 600 different types of coral can be found in the Great Barrier Reef Marine Park, and all of them come in a variety of shapes, sizes and colours. With some of the less demanding inhabitants you can hone your skills. Like its name suggests, staghorn coral is a species of coral that looks a bit like the antlers of a male deer. Type of Coral: Softie. Lighting: Moderate and Moderate to Low. The tentacles can end in little hammer-shaped polyps or tentacles with short knobby branches that look like frogspawn. If an internal link led you here, you may wish to change the link to point directly to the intended article. Within these two tentacle types there are some which grow in a branching form. Euphyllia is a hard coral which has long flowing tentacles. Distribution / Background Protopalythoa Coral Information: The Protopalythoa genus was described by Verrill in 1900. Despite looking like plants, these corals are actually colonies of very small animals called coral polyps which are closely related to jellyfish. The skeletons, however, are always white. The taxonomy of the Zoanthids has been very difficult and though some species are described, it is still largely speculative. When the polyps are retracted, the skeleton has corallites that twist and turn throughout the colony, giving it a maze-like appearance. Sinularia dura is an octocoral, meaning that each polyp has 8 tentacles. Types of Coral The following genera are those corals usually referred to as Small Polyp Stony (SPS) Corals: Most of these are referred to by these names since the resemble a giant lettuce head or other leafy structures. Other common names. Corallorhiza odontorhiza is the scientific, Latin or binomial name of the Autumn Coral Root.Specifically, a scientific name includes at least two names. Some Polyps, such as button polyps, will also benefit from meaty food such as brine shrimp or plankton. is the phylum of animals that contains corals, jellyfish (sea jellies), sea anemones, sea pens, and hydrozoans. There are around 49 species in this genus. A solitary coral individual is called a corallum (plural = coralla), while an individual within a colony is called a corallite.Rugose corals made their skeletons from calcite; this is a significant difference relative to hexacorals, which make their skeletons out of aragonite. The Atlantic Palythoa include P. caribaeorum and P. mammillosa and some Pacific Palythoa are P. caesia, P. psammophila, and P. tuberculosa. The polyp may be solitary, as in the sea anemone, or colonial, as in coral, and is sessile (attached to a surface). The second time the scientific name is written, abbreviate the genus by using the first letter, capitalize it, and use a period. Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals.Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton.The basic unit of the adult is the polyp; this consists of a cylindrical column topped by a disc with a central mouth surrounded by tentacles. Staghorn Coral. Each polyp has a saclike body and a mouth that is encircled by stinging tentacles. Polyp (cartoonist) This disambiguation page lists articles associated with the title Polyp. There are two main types of corals — hard and soft. The first is a gastrovascular cavity that opens at only one end. Scientific name Family: Zoanthidae Species: Protopalythoa mutuki. Care Level: Easy. The mouth is surrounded by a number of tentacles. As each generation of polyps dies and their exoskeleton remains, the coral grows a bit larger and because each polyp is so small, hard corals grow at a very very slow rate. Soft corals also live in colonies, that often resemble brightly coloured plants or trees, and are easy to tell apart from hard corals as their polyps have tentacles that occur in numerals of 8, and have a distinctive feathery appearance. The tissue that connects colonial coral polyps and contains structures that allows corals to share nutrients. b. Other Common Names: Starburst Polyps, Eight Tentacle Polyps, Mat Polyps, Daisy Polyps Description: Star Polyps are a favorite coral for beginners and advanced hobbyists alike.

Distribution / Background Palythoa Coral Information: The Palythoa genus was described by Lamouroux in 1816. All coral polyps share two basic structural features with other members of their phylum. Corals receive their distinctive colors from algae cells called zooxanthellae embedded within the animals' transparent flesh. The branch or mound that we often call “a coral” is actually made up of thousands of tiny animals called polyps. The grooved brain coral appears tan, yellow-brown, or brownish gray. Soft corals are found in oceans from the equator to the north and south poles, generally in caves or ledges. The scientific name for the cabbage leather coral is Sinularia dura. Temperament: Peaceful . The waving polyps flowing in the current add movement and texture to the aquarium. Distribution / Background Protopalythoa Coral Information: The Protopalythoa genus was described by Verrill in 1900. The polyps of colonial forms are 1 to 30 mm (0.04 to 1.2 inches) in diameter. Coral polyps live on the calcium carbonate exoskeletons of their ancestors, adding their own exoskeleton to the existing coral structure. 13. Forming round boulders, colonies have deep interconnected valleys that contain polyps along with broad ridges that have wide, trough-like grooves running down the middle. Stony corals occur in all oceans from the tidal zone to depths of nearly 6,000 metres (about 20,000 feet). Appearance. An easy beginner coral, can spread quickly. Rugose corals may be either solitary or colonial. When damaged, some cnidarians can regenerate their body parts, making them effectively immortal.
