Ras Muhammad National Park
Ras Mohammad ( arz, راس محمد ', ; ar, رأس محمد ') is a national park in Egypt at the southern extreme of the Sinai Peninsula, overlooking the Gulf of Suez on the west and the Gulf of Aqaba to the east. History When the Sinai Peninsula was returned to Egypt, Ras Muhammad was declared for protection from fishing and other human activities. Some of the fishing methods, such as using dynamite and knives were also impacting on the coral reef and the fish populations. In 1983, the Egyptian Environmental Affairs Agency (EEAA) established the area as a marine reserve for the protection of marine and terrestrial wildlife. The park was also established to protect against urban sprawl from Sharm El Sheikh and other coastal development. The name literally means "Mohammad's Head", where "head" in this instance means " headland". It is said in the area that the name arose because in side view the contour of the cliff looks like the profile of a bearded man's face, with horizo ...

Sanafir Island
Sanafir Island ( ar, جزيرة صنافر, Geziret Ṣanafir, ) is a Saudi island in the Straits of Tiran east of Tiran Island. It is about it is located at the entrance to the Straits of Tiran, which separates the Gulf of Aqaba from the Red Sea. The island is about 2.5 km from Tiran Island. The island are characterized by floating coral reefs. The island was under Egyptian control in the past but now it is returned back under Saudi Arabia sovereignty since the 8 April 2016, after the completion of transfer procedures. On 17 June 2017, Egyptian President Abdel Fattah el-Sisi ratified the maritime demarcation agreement between the two countries. It was adopted on maps and official documents on 17 August 2017 and approved by the Egyptian House of Representatives on 14 June 2017, which approved the transfer of the island and its neighbor to Saudi Arabia. The United Nations was notified in accordance with the Charter of Article 102 of the provisions of subsidiarity and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Thistlegorm
SS ''Thistlegorm'' was a British cargo steamship that was built in North East England in 1940 and sunk by German bomber aircraft in the Red Sea in 1941. Her wreck near Ras Muhammad is now a well-known diving site. Building J.L. Thompson and Sons built ''Thistlegorm'' in Sunderland, County Durham, as yard number 599. She was launched on 9 April 1940 and completed on 24 June. Her registered length was , her beam was and her depth was . Her tonnages were and . The North Eastern Marine Engineering built her engine, which was a three-cylinder triple-expansion engine rated at 365 NHP or 1,850 IHP. ''Thistlegorm'' was built for Albyn Line, who registered her at Sunderland. Her UK official number was 163052 and her wireless telegraphy call sign was GLWQ. The Ministry of War Transport partly funded ''Thistlegorm''. She was a defensively equipped merchant ship (DEMS) with a mounted on her stern and a heavy-calibre machine gun for anti-aircraft cover. The ship completed three s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many 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 planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermatypic
Hermatypic corals are those corals in the order Scleractinia which build reefs by depositing hard calcareous material for their skeletons, forming the stony framework of the reef. Corals that do not contribute to coral reef development are referred to as ahermatypic (non-reef-building) species. Many reef-forming corals contain symbiotic photosynthetic zooxanthella Zooxanthellae is a colloquial term for single-celled dinoflagellates that are able to live in symbiosis with diverse marine invertebrates including demosponges, corals, jellyfish, and nudibranchs. Most known zooxanthellae are in the genus '' Sym ...e, which contribute to their nutritional needs. The term "hermatypic" is sometimes misused, being assumed to apply to all zooxanthellate corals. However, there are zooxanthellae in many non reef-forming corals; and not all hermatypic corals in shallow water contain zooxanthellae. Further, some hermatypic corals live at depths to which light cannot penetrate; they form dee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fringing Reef
A fringing reef is one of the three main types of coral reef. It is distinguished from the other main types, barrier reefs and atolls, in that it has either an entirely shallow backreef zone (lagoon) or none at all. If a fringing reef grows directly from the shoreline, then the reef flat extends to the beach and there is no backreef. In other cases (e.g., most of the Bahamas), fringing reefs may grow hundreds of yards from shore and contain extensive backreef areas within which it contains food and water, examples are Philippines, Indonesia, Timor-Leste, the western coast of Australia, the Caribbean, East Africa, and Red Sea. Charles Darwin believed that fringing reefs are the first kind of reefs to form around a landmass in a long-term reef growth process.Kennedy, D.M. and Woodroffe, C.D. 2002.Fringing reef growth and morphology: a review. ''Earth-Science Reviews''. 57:255-277. The largest fringing coral reef in the world is the Ningaloo Reef, stretching to around along the coas ...

Bird Migration
Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs in predation and mortality, including from hunting by humans, and is driven primarily by the availability of food. It occurs mainly in the northern hemisphere, where birds are funneled onto specific routes by natural barriers such as the Mediterranean Sea or the Caribbean Sea. Migration of species such as storks, turtle doves, and swallows was recorded as many as 3,000 years ago by Ancient Greek authors, including Homer and Aristotle, and in the Book of Job. More recently, Johannes Leche began recording dates of arrivals of spring migrants in Finland in 1749, and modern scientific studies have used techniques including bird ringing and satellite tracking to trace migrants. Threats to migratory birds have grown with habitat destruction, especially of stopover and wintering sites, as wel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wadis
Wadi ( ar, وَادِي, wādī), alternatively ''wād'' ( ar, وَاد), North African Arabic Oued, is the Arabic term traditionally referring to a valley. In some instances, it may refer to a wet (ephemeral) riverbed that contains water only when heavy rain occurs. Etymology The term ' is very widely found in Arabic toponyms. Some Spanish toponyms are derived from Andalusian Arabic where ' was used to mean a permanent river, for example: Guadalcanal from ''wādī al-qanāl'' ( ar, وَادِي الْقَنَال, "river of refreshment stalls"), Guadalajara from ''wādī al-ḥijārah'' ( ar, وَادِي الْحِجَارَة, "river of stones"), or Guadalquivir, from ''al-wādī al-kabīr'' ( ar, اَلْوَادِي الْكَبِير, "the great river"). General morphology and processes Wadis are located on gently sloping, nearly flat parts of deserts; commonly they begin on the distal portions of alluvial fans and extend to inland sabkhas or dry lakes.

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
