Amphiprion Ephippium
The red saddleback anemonefish, ''Amphiprion ephippium'', also known as the saddle anemonefish, is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes. 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 commonly according to distribution, but also based on sex, age and host anemone. Clownfish are found in warmer waters of the Indian and Pa ...

Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyology, ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfurt (Oder), Frankfort on the Oder with a treatise on skin dis ...

External Fertilization
External fertilization is a mode of reproduction in which a male organism's sperm fertilizes a female organism's egg outside of the female's body. It is contrasted with internal fertilization, in which sperm are introduced via insemination and then combine with an egg inside the body of a female organism. External fertilization typically occurs in water or a moist area to facilitate the movement of sperm to the egg. The release of eggs and sperm into the water is known as spawning. In motile species, spawning females often travel to a suitable location to release their eggs. However, sessile species are less able to move to spawning locations and must release gametes locally. Among vertebrates, external fertilization is most common in amphibians and fish. Invertebrates utilizing external fertilization are mostly benthic, sessile, or both, including animals such as coral, sea anemones, and tube-dwelling polychaetes. Benthic marine plants also use external fertilization to reproduce. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Australian Museum
The Western Australian Museum is a statutory authority within the Culture and the Arts Portfolio, established under the ''Museum Act 1969''. The museum has six main sites. The state museum, now known as WA Museum Boola Bardip, officially re-opened on 21 November 2020 in the Perth Cultural Centre. The other sites are: the WA Maritime Museum and WA Shipwrecks Museum in Fremantle, the Museum of the Great Southern in Albany, the Museum of Geraldton in Geraldton, and the Museum of the Goldfields in Kalgoorlie-Boulder. History Established in 1891 in the Old Perth Gaol, it was known as the Geological Museum and consisted of geological collections. In 1892, ethnological and biological exhibits were added, and in 1897, the museum officially became the Western Australian Museum and Art Gallery. The museum employed collectors to obtain series of specimens; Tunney ventured across the state from 1895 to 1909 obtaining animals and, later, the tools and artefacts of the indigenous inhabi ...

Sebae Anemone
The sebae anemone (''Heteractis crispa''), also known as leathery sea anemone, long tentacle anemone, or purple tip anemone, is a species of sea anemone belonging to the family Stichodactylidae and native to the Indo-Pacific area. It was first described in 1834 by Wilhelm Hemprich and Christian Gottfried Ehrenberg as ''Actinia crispa''. The name accepted by the World Register of Marine Species is ''Radianthus crispa''. Description The sebae anemone is characterized by a flared oral disc which 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. The ...

Bubble-tip Anemone
Bubble-tip anemone (''Entacmaea quadricolor'') is a species of sea anemone in the family Actiniidae. Like several anemone species, ''E. quadricolor'' can support several anemonefish species, and displays two growth types based on where they live in the water column, one of which gives it the common name, due to the bulbous tips on its tentacles. Distribution ''Entacmaea quadricolor'' is widespread throughout the tropical waters of the Indo-Pacific area, including the Red Sea. ''E. quadricolor'' anemones appear in a variety of morphs, including rose, orange, red, and standard green. This sea anemone can grow to be up to in diameter, and obtains the majority of its energy from solar radiation via its symbiotic zooxanthellae. A characteristic of ''E. quadricolor'' is its ability to maintain a symbiotic relationship with the anemonefish, which can be "hosted" by the anemone by providing it with defence against predators and also providing some nourishment. In turn, the anemon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tranquebar
Tharangambadi (), formerly Tranquebar ( da, Trankebar, ), is a town in the Mayiladuthurai district of the Indian state of Tamil Nadu on the Coromandel Coast.

Amphiprion Rubrocinctus
''Amphiprion rubrocinctus'', also known as the Australian clownfish or red anemonefish, is a species of anemonefish that is endemic to north west Australia. 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 side of ''A. rubrocinctus'' has blackish or dark brown sides with red snout, breast, belly and fins. it has a single white head bar that is often poorly developed and lacking a pronounced black margin. Color variations Some anemonefish species have co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
