Lamellibrachia Donwalshi
''Lamellibrachia'' is a genus of tube worms related to the giant tube worm, ''Riftia pachyptila''. They live at deep-sea cold seeps where hydrocarbons (oil and methane) leak out of the seafloor, and are entirely reliant on internal, sulfide-oxidizing bacterial symbionts for their nutrition. The symbionts, gammaproteobacteria, require sulfide and inorganic carbon (carbon dioxide). The tube worms extract dissolved oxygen and hydrogen sulfide from the sea water with the crown of plumes. Species living near seeps can also obtain sulfide through their "roots", posterior extensions of their body and tube. Several sorts of hemoglobin are present in the blood and coelomic fluid to bind to the different components and transport them to the symbionts. ''L. luymesi'' provides the bacteria with hydrogen sulfide and oxygen by taking them up from the environment and binding them to a specialized hemoglobin molecule. Unlike the tube worms that live at hydrothermal vents, ''L. luymesi'' uses a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamellibrachia Luymesi
''Lamellibrachia luymesi'' is a species of tube worms in the family Siboglinidae. It lives at deep-sea cold seeps where hydrocarbons (oil and methane) are leaking out of the seafloor. It is entirely reliant on internal, sulfide-oxidizing bacterial symbionts for its nutrition. These are located in a centrally located "trophosome". ''Lamellibrachia luymesi'' provides the bacteria with hydrogen sulfide and oxygen by taking them up from the environment and binding them to a specialized hemoglobin molecule. Unlike the tube worms ''Riftia pachyptila'' that live at hydrothermal vents, ''L. luymesi'' uses a posterior extension of its body called the root to take up hydrogen sulfide from the seep sediments. ''L. luymesi'' may also help fuel the generation of sulfide by excreting sulfate through their roots into the sediments below the aggregations. To support the carbon fixation they need for maintenance and growth, ''L. luymesi'' needs to extract sulfide, oxygen, and inorganic carbon ...

Vestimentiferan
Siboglinidae is a family of polychaete annelid worms whose members made up the former phyla Pogonophora and Vestimentifera (the giant tube worms). The family is composed of about 100 species of vermiform creatures which live in thin tubes buried in sediments (Pogonophora) or in tubes attached to hard substratum (Vestimentifera) at ocean depths ranging from . They can also be found in association with hydrothermal vents, methane seeps, sunken plant material, and whale carcasses. The first specimen was dredged from the waters of what is now Indonesia in 1900. These specimens were given to French zoologist Maurice Caullery, who studied them for nearly 50 years. Anatomy Most siboglinids are less than in diameter, but in length. They inhabit tubular structures composed of chitin and fixed to rocks or substrate. The tubes are often clustered together in large colonies. Their bodies are divided into four regions. The anterior end is called the cephalic lobe, which bears from one to ...

Marina F
A marina (from Spanish , Portuguese and Italian : ''marina'', "coast" or "shore") is a dock or basin with moorings and supplies for yachts and small boats. A marina differs from a port in that a marina does not handle large passenger ships or cargo from freighters. The word ''marina'' may also refer to an inland wharf on a river or canal that is used exclusively by non-industrial pleasure craft such as canal narrowboats. Emplacement Marinas may be located along the banks of rivers connecting to lakes or seas and may be inland. They are also located on coastal harbors (natural or man made) or coastal lagoons, either as stand alone facilities or within a port complex. History In the 19th century, the few existing pleasure craft shared the same facilities as trading and fishing vessels. The marina appeared in the 20th century with the popularization of yachting. Facilities and services A marina may have refuelling, washing and repair facilities, marine and boat chandle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eve C
Eve (; ; ar, حَوَّاء, Ḥawwāʾ; el, Εὕα, Heúa; la, Eva, Heva; Syriac: romanized: ) is a figure in the Book of Genesis in the Hebrew Bible. According to the origin story, "Creation myths are symbolic stories describing how the universe and its inhabitants came to be. Creation myths develop through oral traditions and therefore typically have multiple versions." of the Abrahamic religions, she was the first woman, yet some debate within Judaism has also given that position to Lilith. Eve is known also as Adam's wife. According to the second chapter of Genesis, Eve was created by God (Yahweh) by taking her from the rib of Adam, to be Adam's companion. Adam is charged with guarding and keeping the garden before her creation; she is not present when God commands Adam not to eat the forbidden fruit – although it is clear that she was aware of the command. She decides to eat the forbidden fruit from the tree of the knowledge of good and evil after she hears t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
