Atriolum Robustum
''Atriolum robustum'' is a colonial tunicate or sea squirt in the family ''Didemnidae''. It is native to the western and central Indo-Pacific where it is usually found anchored to a hard surface in shallow water. Description A colony of ''Atriolum robustum'' consists of a number of hollow, urn-shaped zooids up to long, each with a large circular terminal hole, the atrial siphon, and connected by an encrusting base. The tunic (body wall) is firm to the touch and is perforated by a number of pore-like buccal siphons, each raised on a slight elevation, giving the zooid a pine cone-like appearance. The tunic contains a red pigment but the colour of this is often masked by the presence of yellowish-green cyanobacteria (''Prochloron'' sp.) and may only be visible in the interior and at the rim of the atrial syphon. This sea squirt is sometimes confused with ''Didemnum molle'' but that species has a network of internal channels and exudes mucus, making it sticky to the touch. Distribu ...

Siphonogorgia Godeffroyi
''Siphonogorgia godeffroyi'', the cherry blossom coral or Godeffroy's Soft Coral, is a species of soft coral in the family Nidaliidae. It is native to the central Indo-Pacific region. Its range includes Indonesia, the Philippines and Papua New Guinea. This species was first described in 1874 by the Swiss biologist Albert von Kölliker Albert von Kölliker (born Rudolf Albert Kölliker'';'' 6 July 18172 November 1905) was a Swiss anatomist, physiologist, and histologist. Biography Albert Kölliker was born in Zurich, Switzerland. His early education was carried on in Zurich, .... Description ''Siphonogorgia godeffroyi'' is an arborescent coral with red or pink bare branches. The polyps are white and star-like and are concentrated on the tips of small branches. This species feeds on plankton. It is found at depths between and grows on both rocky and coral reefs, on rock ledges, on reef slopes and under overhangs.

Phytoplankton
Phytoplankton () are the autotrophic (self-feeding) components of the plankton community and a key part of ocean and freshwater ecosystems. The name comes from the Greek words (), meaning 'plant', and (), meaning 'wanderer' or 'drifter'. Phytoplankton obtain their energy through photosynthesis, as do trees and other plants on land. This means phytoplankton must have light from the sun, so they live in the well-lit surface layers (euphotic zone) of oceans and lakes. In comparison with terrestrial plants, phytoplankton are distributed over a larger surface area, are exposed to less seasonal variation and have markedly faster turnover rates than trees (days versus decades). As a result, phytoplankton respond rapidly on a global scale to climate variations. Phytoplankton form the base of marine and freshwater food webs and are key players in the global carbon cycle. They account for about half of global photosynthetic activity and at least half of the oxygen production, despite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polycarpa Aurata
''Polycarpa aurata'', also known as the ox heart ascidian, the gold-mouth sea squirt or the ink-spot sea squirt, is a species of tunicate in the family Styelidae. Description ''Polycarpa aurata'' grows to a height of . It has an urn-shaped, hollow body with two siphons, one at the top and the other on the side. The body colour of this tunicate is white with purple and orange patches and purple lines. The inside is yellow or orange and this is visible around the rim of the siphons. Distribution This species is found in the tropical eastern Indian Ocean and the western Pacific Ocean. Its range includes the Philippines, Indonesia and northern Australia. Its depth range is . Biology Tunicates feed by drawing water in through the branchial siphon at the top, filtering out phytoplankton, bacteria and other food particles, before expelling the water through the atrial siphon at the side. Sometimes hydroids and algae grow on the outside of the tunicate and nudibranchs such as ''Nem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Komodo National Park
Komodo National Park (Indonesian: ''Taman Nasional Komodo'') is a national park in Indonesia located within the Lesser Sunda Islands in the border region between the provinces of East Nusa Tenggara and West Nusa Tenggara. The park includes the three larger islands Komodo, Padar and Rinca, and 26 smaller ones, with a total area of 1,733 km2 (603 km2 of it land). The national park was founded in 1980 to protect the Komodo dragon, the world's largest lizard. Later it was dedicated to protecting other species, including marine species. In 1991 the national park was declared a UNESCO World Heritage Site. Komodo National Park has been selected as one of the New7Wonders of Nature. The waters surrounding Komodo island contain rich marine biodiversity. Komodo islands is also a part of the Coral Triangle, which contains some of the richest marine biodiversity on Earth.

Soft Coral
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are Sessility (zoology), sessile colony (biology), colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyp (zoology), polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan (implement), fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, r ...

Predation
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inv ...

Detritus
In biology, detritus () is dead particulate organic material, as distinguished from dissolved organic material. Detritus typically includes the bodies or fragments of bodies of dead organisms, and fecal material. Detritus typically hosts communities of microorganisms that colonize and decompose (i.e. remineralize) it. In terrestrial ecosystems it is present as leaf litter and other organic matter that is intermixed with soil, which is denominated " soil organic matter". The detritus of aquatic ecosystems is organic material that is suspended in the water and accumulates in depositions on the floor of the body of water; when this floor is a seabed, such a deposition is denominated "marine snow". Theory The corpses of dead plants or animals, material derived from animal tissues (e.g. molted skin), and fecal matter gradually lose their form due to physical processes and the action of decomposers, including grazers, bacteria, and fungi. Decomposition, the process by which or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zooplankton
Zooplankton are the animal component of the planktonic community ("zoo" comes from the Greek word for ''animal''). Plankton are aquatic organisms that are unable to swim effectively against currents, and consequently drift or are carried along by currents in the ocean, or by currents in seas, lakes or rivers. Zooplankton can be contrasted with phytoplankton, which are the plant component of the plankton community ("phyto" comes from the Greek word for ''plant''). Zooplankton are heterotrophic (other-feeding), whereas phytoplankton are autotrophic (self-feeding). This means zooplankton cannot manufacture their own food but must eat other plants or animals instead — in particular they eat phytoplankton. Zooplankton are generally larger than phytoplankton, most are microscopic, but some (such as jellyfish) are macroscopic and can be seen with the naked eye. Many protozoans (single-celled protists that prey on other microscopic life) are zooplankton, including zooflagellates, fo ...
