Radianthus Magnifica
''Radianthus magnifica'', also known by as magnificent sea anemone or Ritteri anemone, is a species of sea anemone in the family Stichodactylidae that is native to the Hawaii, USA, Indo-Pacific. Description The magnificent sea anemone is characterized by a flared oral disc, which reaches between 20 and 50 cm in diameter, but in some specimens, this can reach 1 m. The oral disc, the base of the tentacles, and the oral orifice have the same color, going from light beige to white. The numerous tentacles exceed 8 cm long. The sea anemone, being a member of the Hexacorallia, usually carries tentacles in multiples of six that are positioned in concentric circles. Their tips are fingered and often lighter in coloration than the tentacle body and are sometimes vividly colored. Its specific scientific name, ''magnifica'', and its vernacular name come from the bright color of the column, which is the visible outer structure when the animal retracts, and these range from electri ...

Pink Skunk Clownfish
The pink skunk clownfish (''Amphiprion perideraion''), also known as the pink anemonefish, is a species of anemonefish that is widespread from northern Australia through the Malay Archipelago and Melanesia. Like all anemonefishes, it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host. It is a sequential hermaphrodite with a strict size-based dominance hierarchy; the female is largest, the breeding male is second largest, and the male nonbreeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male changes to female if the sole breeding female dies, with the largest nonbreeder becoming the breeding male. Description The body of ''A. perideraion'' is pink to peach. It has the white stripe along the dorsal ridge that is common to all members of the skunk complex and a white head bar running vertically just behind the eye. While the largest species of anemonefish can reach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Reproduction
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete ( haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes ( diploid). This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes. In placental mammals, sperm cells exit the penis through the male urethra and enter the vagina during copulation, while egg cells enter the uterus through the oviduct. Other vertebrates of both sexes possess a cloaca for the release of sperm or egg cells. Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. Sexual reproduction also occurs in some unicellular eukaryotes. Sexual reproduction does not occur in pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphiprion Chrysopterus
The orange-fin anemonefish (''Amphiprion chrysopterus'') is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes, found in the Western Pacific north of the Great Barrier Reef from the surface to 20 m, to include the Pacific Ocean between Queensland, Australia, and New Guinea to the Marshall and Tuamotus Islands.

Amphiprion Akindynos
''Amphiprion akindynos'', the Barrier Reef anemonefish, is a species of anemonefish that is principally found in the Great Barrier Reef of Australia, but also in nearby locations in the Western Pacific. The species name 'akindynos' is Greek, meaning 'safe' or 'without danger' in reference to the safety afforded amongst the tentacles of its host anemone. Like all anemonefishes it forms a symbiotic mutualism with sea anemones and is unaffected by the stinging tentacles of the host anemone. It is a sequential hermaphrodite with a strict size-based dominance hierarchy: the female is largest, the breeding male is second largest, and the male non-breeders get progressively smaller as the hierarchy descends. They exhibit protandry, meaning the breeding male will change to female if the sole breeding female dies, with the largest non-breeder becomes the breeding male. The fish's natural diet includes zooplankton. Description Adults are an orange-brown colour with two white bars with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphiprion Akallopisos
The nosestripe clownfish or nosestripe anemonefish, skunk clownfish, ''Amphiprion akallopisos'', is an anemonefish (also called clownfish) that lives in association with sea anemones. ''A. akallopisos'' is found in the Indian Ocean. It resides in shallow inshore reefs as deep as 15 m with a moderate to strong current. The skunk clownfish can also be kept in captivity by aquarists. Description The skunk clownfish is identified by a light orange color, with a single, narrow, white stripe running from the mouth to the caudal peduncle, and can grow as large as 11 cm in lengtLike other anemonefish, the skunk clownfish is a Hermaphrodite, protandrous hermaphrodite, and maintains a hierarchy within the host anemone that consists of a mating pair, of which the female is the largest, and non-mating males which get progressively smaller in size.

Nestedness
Nestedness is a measure of structure in an ecological system, usually applied to species-sites systems (describing the distribution of species across locations), or species-species interaction networks (describing the interactions between species, usually as bipartite networks such as hosts-parasites, plants-pollinators, etc.). A system (usually represented as a matrix) is said to be nested when the elements that have a few items in them (locations with few species, species with few interactions) have a subset of the items of elements with more items. Imagine a series of islands that are ordered by their distance from the mainland. If the mainland has all species, the first island has a subset of mainland's species, the second island has a subset of the first island's species, and so forth, then this system is perfectly nested. Measures of nestedness One measurement unit for nestedness is a system's 'temperature Temperature is a physical quantity that quantitatively expresses ...

Anemonefish
Clownfishes or anemonefishes (genus ''Amphiprion'') are saltwater fishes found in the warm and tropical waters of the Indo-Pacific. They inhabit mainly coral reefs and have a distinctive colouration typically consisting of white vertical bars on a red, orange, yellow, brown or black background. Clownfish developed a Mutualism (biology), mutually beneficial relationship with sea anemones, which they rely on for shelter and protection from predators. In turn, clownfish will protect the anemone from anemone-eating fish, as well as clean and fan them, and attract zooxanthellae, beneficial microorganisms with their waste. Clownfish are omnivorous and mostly feed on plankton. They live in groups consisting of a breeding female and male, along with some non-breeding individuals. Clownfish have a size-based dominance hierarchy with the female ranking at the top, followed by the male and then the largest non-breeder and so on. When the female disappears, the male sequential hermaphroditis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Analyses
Genetic analysis is the overall process of studying and researching in fields of science that involve genetics and molecular biology. There are a number of applications that are developed from this research, and these are also considered parts of the process. The base system of analysis revolves around general genetics. Basic studies include identification of genes and inherited disorders. This research has been conducted for centuries on both a large-scale physical observation basis and on a more microscopic scale. Genetic analysis can be used generally to describe methods both used in and resulting from the sciences of genetics and molecular biology, or to applications resulting from this research. Genetic analysis may be done to identify genetic/inherited disorders and also to make a differential diagnosis in certain somatic diseases such as cancer. Genetic analyses of cancer include detection of mutations, fusion genes, and DNA copy number changes. History Much of the r ...
