Phyllospora Comosa
''Phyllospora comosa'', known as crayweed, is a species of brown algae in the Seirococcaceae family that is a type of temperate seaweed forest important as habitat for many marine species and also for producing oxygen and capturing atmospheric carbon. It is found in the oceans around Australia and New Zealand. Crayweed grows up to in length and forms dense, shallow forests. It is abundant in cooler waters along the south-eastern coastline of Australia, around Tasmania and in South Australia and occurs to a depth of around on the east coast and farther south to about . On some Tasmanian coasts it can occur depths of at . It used to occur around Sydney but has disappeared from metropolitan areas under pressure from human activities during the 1970s and 1980s. The algae have a central main axis, usually up to long, which bear many branches along their length, with closely arranged, leaf-like laterals. Some laterals have conceptacles, in which develop cells which produce sperm a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Alga
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, ''Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is ''Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,500 ...

Q21522202
Q, or q, is the seventeenth letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is pronounced , most commonly spelled ''cue'', but also ''kew'', ''kue'' and ''que''. History The Semitic sound value of Qôp was (voiceless uvular stop), and the form of the letter could have been based on the eye of a needle, a knot, or even a monkey with its tail hanging down. is a sound common to Semitic languages, but not found in many European languages. Some have even suggested that the form of the letter Q is even more ancient: it could have originated from Egyptian hieroglyphics. In an early form of Ancient Greek, qoppa (Ϙ) probably came to represent several labialized velar stops, among them and . As a result of later sound shifts, these sounds in Greek changed to and respectively. Therefore, qoppa was transformed into two letters: qoppa, which stood for the number 9 ...
