Radianthus Crispa
The sebae anemone (''Radianthus crispa''), also known as leathery sea anemone, long tentacle anemone, or purple tip anemone, is a species of sea anemone in the family Stichodactylidae and native to the Indo-Pacific. It was first described in 1834 by Wilhelm Hemprich and Christian Gottfried Ehrenberg as ''Actinia crispa''. Description The sebae anemone is characterized by a flared oral disc that reaches between 20 and 50 cm in diameter and with multiple and long tentacles measuring 10 to 15 cm. These tentacles have rounded tip and the end is often colored with a purple or blue spot. The column, external structure of an anemone visible when the animal is closed, is gray in color and dotted with sticky whitish "warts". The sea anemone, being member of the Hexacorallia, usually carries a number of tentacles multiple of six and they are positioned in concentric circles. These are light beige to purple. Distribution and habitat The sebae anemone is widespread throughout the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red Sea Clownfish
The Red Sea Clownfish (''Amphiprion bicinctus'', meaning "both sawlike with two stripes"), commonly known as the Red Sea or two-banded anemonefish is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes. Like other species of the genus, the fish feeds on algae and zooplankton in the wild. Characteristics of Anemonefish Clownfish or anemonefish are fishes that, in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see . The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators, and parasites. Clownfish are small-sized, , and depending on species, they are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. Within species there may be color variations, most commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Amphiprion Leucokranos
''Amphiprion leucokranos'', the white bonnet anemonefish, is a naturally occurring hybrid anemonefish found in the western central Pacific Ocean. 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 dominance hierarchy, features which are critical to the direction of gene flow. Description The body of ''A. leucokranosis'' is orange or light brown and with a white head bar and a white mark on the top of its head, giving rise to its common name of white bonnet anemonefish. The head band may be continuous or not. They have 9 dorsal spines, 2 anal spines, 18-19 dorsal soft rays and 13-14 anal soft rays. They reach a maximum length of . Hybridisation There has been a long-standing theory that ''A. leucokranosis'' was a naturally occurring hybrid between ''A. chrysopterus'' and ''A. sandaracinos'', with the fish being experimentally created in captiv ...

Amphiprion Barberi
''Amphiprion barberi'' is a species of anemonefish that is found in the western Pacific Ocean. It was previously considered a geographic color variation of other anemonefish, initially ''Amphiprion rubrocinctus'' from 1972 and then '' Amphiprion melanopus'' from 1980 however further study and DNA sequencing resulted in ''A. barberi'' being described as a new species in 2008. 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 sized 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 The body of adults are generall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...

Amphiprion Sebae
''Amphiprion sebae'', also known as the sebae clownfish, is an anemonefish found in the northern Indian Ocean, from Java to the Arabian Peninsula. Like all anemonefish it is usually found living in association with sea anemones. While the common name of ''Heteractis crispa'', the sebae anemone, suggests an association, it is normally found with the Stichodactyla haddoni or saddle anemone. ''A. sebae'', like all anemonefish, lives in a symbiotic relationship with the host anemone where the fish is unaffected by the stinging tentacles of the anemone. In a group of clownfish, Only two clownfish, a male and a female, in a group reproduce through external fertilization. Clownfish are sequential hermaphrodites, changing from male to female, with a strict dominance hierarchy and only the largest fish being female. Description The body of ''A. sebae'' is blackish or dark brown with a yellow snout, breast and belly. It has two broad white bars., with the mid-body bar angled backwards. ...
