Thor Amboinensis
''Thor amboinensis'', commonly known as the squat shrimp or sexy shrimp, is a species of shrimp found across the Indo-West Pacific and in parts of the Atlantic Ocean. It lives symbiotically on corals, sea anemones and other marine invertebrates in shallow reef communities. Description ''Thor amboinensis'' is a small shrimp growing to a length of about . It is an olive brown colour with symmetrically placed white patches edged with thin blue lines. It characteristically carries its abdomen curved upwards with its tail fan above its head. Distribution Though it is named for Ambon or Amboyna Island, one of the Maluku Islands in Indonesia, ''Thor amboinensis'' has a pantropical distribution being found in the Red Sea, the Indian Ocean, the Pacific Ocean, the Caribbean Sea, the Gulf of Mexico, Madeira and the Canary Islands. Ecology ''Thor amboinensis'' forms a commensal relationship with another invertebrate, usually a shallow water sea anemone or mushroom coral. The species mos ...

Johannes Govertus De Man
Johannes Govertus de Man (2 May 1850 in Middelburg – 9 January 1930 in Middelburg), was a Dutch biologist. He was assistant curator at the (Dutch for ''national natural history museum'') in Leiden, where he specialised in free-living nematodes and decapod crustaceans, although he also wrote papers on flatworms, sipunculids and, in his dissertation only, vertebrates. His change away from vertebrates disappointed the director of the museum, and de Man left his job there after eleven years. For the rest of his life, de Man worked at his parents' house in Middelburg and later at a house near the shore at Yerseke in the Oosterschelde estuary, relying on his family's private income.

Lebrunia Danae
''Lebrunia neglecta'' is a species of sea anemone in the family Aliciidae. It is found in the Caribbean Sea and Gulf of Mexico. Description ''Lebrunia neglecta'' is an unusual sea anemone in that its tentacles are almost hidden by the ring of six much branching large frond-like pseudotentacles that grow up from the rim of the oral disc. These are some shade of pale or darker brown and have densely branched tips. Below these, on the side of the frond are small, whitish spherical vesicles containing nematocysts that are powerful enough to sting a human. After contact with a prey item, the pseudotentacles retract and the tentacles, which are also armed with nematocysts, grasp the prey and draw it into the mouth. The column of the anemone is usually invisible, being anchored in a crevice. This species can grow to a diameter of . It is very similar in appearance to the closely related '' Lebrunia coralligens'', but the pseudotentacles of that species are much less branched, and often ...

Nano Reef
A reef aquarium or reef tank is a marine aquarium that prominently displays live corals and other marine invertebrates as well as fish that play a role in maintaining the tropical coral reef environment. A reef aquarium requires appropriately intense lighting, turbulent water movement, and more stable water chemistry than fish-only marine aquaria, and careful consideration is given to which reef animals are appropriate and compatible with each other. Components Reef aquariums consist of a number of components, in addition to the livestock, including: *Display tank: The primary tank in which the livestock are kept and shown. *Stand: A stand allows for placement of the display tank at eye level and provides space for storage of the accessory components. *Sump: An accessory tank in which mechanical equipment is kept. A remote sump allows for a clutter-free display tank. *Refugium: An accessory tank dedicated to the cultivation of beneficial macroalgae and microflora/fauna. The re ...

Marine Aquaria
A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Marine aquaria are further subdivided by hobbyists into fish only (FO), fish only with live rock (FOWLR), and reef aquaria. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. FOWLR and reef tanks use live rock, a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration. Marine fishkeeping is different from its freshwater counterpart because of the fundamental differences in the constitution of saltwater and the resulting differences in the adaptation of its inhabitants. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring. The inhabitants of a marine aquarium are often difficult to acquire and are usually more expensive than freshwater aqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis ("hemimetaboly"), or no metamorphosis (" ametaboly"). Scientific usage of the term is technically precise, and it is not applied to general aspects of cell growth, including rapid growth spurts. Generally organisms with a larva stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. References to "metamorphosis" in mammals are imprecise and only colloquial, but historically idealist ideas of transformation ...

Zoea
Crustaceans may pass through a number of larval and immature stages between hatching from their eggs and reaching their adult form. Each of the stages is separated by a moult, in which the hard exoskeleton is shed to allow the animal to grow. The larvae of crustaceans often bear little resemblance to the adult, and there are still cases where it is not known what larvae will grow into what adults. This is especially true of crustaceans which live as benthic adults (on the sea bed), more-so than where the larvae are planktonic, and thereby easily caught. Many crustacean larvae were not immediately recognised as larvae when they were discovered, and were described as new genera and species. The names of these genera have become generalised to cover specific larval stages across wide groups of crustaceans, such as ''zoea'' and ''nauplius''. Other terms described forms which are only found in particular groups, such as the ''glaucothoe'' of hermit crabs, or the ''phyllosoma'' of slippe ...

Brittle Star
Brittle stars, serpent stars, or ophiuroids (; ; referring to the serpent-like arms of the brittle star) are echinoderms in the class Ophiuroidea, closely related to starfish. They crawl across the sea floor using their flexible arms for locomotion. The ophiuroids generally have five long, slender, whip-like arms which may reach up to in length on the largest specimens. The Ophiuroidea contain two large clades, Ophiurida (brittle stars) and Euryalida (basket stars). Over 2,000 species of brittle stars live today. More than 1,200 of these species are found in deep waters, greater than 200 m deep. Range The ophiuroids diverged in the Early Ordovician, about 500 million years ago. Ophiuroids can be found today in all of the major marine provinces, from the poles to the tropics. Basket stars are usually confined to the deeper parts of this range; Ophiuroids are known even from abyssal (>6,000 m) depths. However, brittle stars are also common members of reef communities, where t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bahamas
The Bahamas (), officially the Commonwealth of The Bahamas, is an island country within the Lucayan Archipelago of the West Indies in the Atlantic Ocean, North Atlantic. It takes up 97% of the Lucayan Archipelago's land area and is home to 88% of the archipelago's population. The archipelagic state consists of more than 3,000 islands, cays, and islets in the Atlantic Ocean, and is located north of Cuba and northwest of the island of Hispaniola (split between the Dominican Republic and Haiti) and the Turks and Caicos Islands, southeast of the U.S. state of Florida, and east of the Florida Keys. The capital is Nassau, Bahamas, Nassau on the island of New Providence. The Royal Bahamas Defence Force describes The Bahamas' territory as encompassing of ocean space. The Bahama Islands were inhabited by the Lucayan people, Lucayans, a branch of the Arawakan-Taino language, speaking Taíno, for many centuries.
