Whitetail Dascyllus
''Dascyllus aruanus'', known commonly as the whitetail dascyllus or humbug damselfish among other vernacular names, is a species of marine fish in the family Pomacentridae. Description Whitetail dascyllus is up to in length but its common size is and is white with three black vertical bars. It appears very similar to the closely related '' D. abudafur''. It may also be mistaken for '' D. melanurus'', which has four black stripes instead of three. They have a small mouth, a flat spine, a black and white body with a large white spot between the eyes. In the first year of life, the damselfish grows to be about 6 centimeters. However, it is fully grown by the end of its second year and remains at around 10 centimeters for another three to four years until it dies. The colors remain the same throughout their lives and serve multiple purposes. It has been hypothesized that the bold contrast of black and white attract fish of the same species, yet display as a sign of their host coral ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dascyllus Abudafur
''Dascyllus abudafur'', the Indian Ocean humbug, is a species of ray-finned fish from the family Pomacentridae, the clownfishes and damselfishes. Distribution It is found in the Red Sea, along the coasts of eastern Africa to South Africa, the Seychelles, Comoros, Madagascar and Mascarene Islands east to the Sunda Islands. Taxonomy It has previously been classified as synonymous with the Pacific humbug (''Dascyllus aruanus'') but mitochondrial and nuclear DNA analysis shows that the two species were are genetically and morphologically different, with different geographic ranges. Due to its close relation with ''D. aruanus'', it is part of the ''D. aruanus'' species complex (''D. aruanus'', ''D. abudafur'', ''D. melanurus''). Etymology The specific name is derived from the Arabic Arabic (, , or , ) is a Central Semitic languages, Central Semitic language of the Afroasiatic languages, Afroasiatic language family spoken primarily in the Arab world.

Dascyllus Marginatus
''Dascyllus marginatus'' (marginate dascyllus or Red Sea dascyllus) is a damselfish endemic to the Western Indian Ocean. It is a site attached fish that lives in corals, usually '' Stylophora pistillata'' and species of Acropora. In these corals it hides at a moment of danger and sleeps at night. It feeds on zooplankton that drifts with the current, and grows to a size of 6 cm in length. ''Dascyllus marginatus'' lives in groups of 2-25 individuals, and while foraging Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. Foraging theory is a branch of behavioral ecology that studies the foraging behavi ... for food around their home coral, group members keep separated and stable foraging spaces.

Sunda Shelf
Geology, Geologically, the Sunda Shelf () is a south-eastern extension of the continental shelf of Mainland Southeast Asia. Major landmasses on the shelf include the Indonesia, Indonesian islands of Bali, Borneo, Java, Madura Island, Madura, and Sumatra, as well as their surrounding smaller islands. It covers an area of approximately 1.85 million km2.va Bemmelen, R.W. (1949). ''The Geology of Indonesia.'' Vol. IA'': General Geology of Indonesia and Adjacent Archipelagoes.'' Matinus Nithoff, The Hague, 723 pp. Sea depths over the shelf rarely exceed 50 metres and extensive areas are less than 20 metres resulting in strong bottom friction and strong tidal friction. Steep undersea gradients separate the Sunda Shelf from the Philippines, Sulawesi, and the Lesser Sunda Islands (not including Bali).

Planktivore
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton. Planktivory can be an important mechanism of top-down control that contributes to trophic cascades in aquatic and marine systems. There is a tremendous diversity of feeding strategies and behaviors that planktivores utilize to capture prey. Some planktivores utilize tides and currents to migrate between estuaries and coastal waters; other aquatic planktivores reside in lakes or reservoirs where diverse assemblages of plankton are present, or migrate vertically in the water column searching for prey. Planktivore populations can impact the abundance and community composition of planktonic species through th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral
Corals are colonial marine invertebrates within the subphylum Anthozoa of the phylum Cnidaria. They typically form compact Colony (biology), colonies of many identical individual polyp (zoology), polyps. Coral species include the important Coral reef, reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many cloning, genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form ...

Acropora
''Acropora'' is a genus of small polyp stony coral in the phylum Cnidaria. Some of its species are known as table coral, elkhorn coral, and staghorn coral. Over 149 species are described. ''Acropora'' species are some of the major reef corals responsible for building the immense calcium carbonate substructure that supports the thin living skin of a reef. Anatomy and distribution Depending on the species and location, ''Acropora'' species may grow as plates or slender or broad branches. Like other corals, ''Acropora'' corals are colonies of individual polyps, which are about 2 mm across and share tissue and a nerve net. The polyps can withdraw back into the coral in response to movement or disturbance by potential predators, but when undisturbed, they protrude slightly. The polyps typically extend further at night to help capture plankton and organic matter from the water. The species are distributed in the Indo-Pacific (over 100 species) and Caribbean (3 species). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, ...
