Eilat's Underwater Observatory Marine Park
Eilat's Coral World Underwater Observatory is a public aquarium, Public park, park and conservation center located in Eilat, Israel. It is the biggest public aquarium in Israel, and it hosts over 800 species. It was founded in 1974 and was the first of its kind. The park and aquarium is located to the south of Eilat's Coral Beach nature reserve. History The park was founded in 1974 by the zoologist and marine biologist David Friedman (zoologist), David Friedman. The idea of the observatory was planned in 1972, it took careful planning to create the observatory without harming the natural environment. The observatory was built completely on land, which was then flooded with water from the Red Sea using armory parts and other metals. The base of the observatory was connected to large iron chains, and after the observatory was placed many corals were planted on and around the observatory in order to repair the damage that was done during the making of the observatory. The coral re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass-bottom Boat
A glass-bottom boat is a boat with sections of glass, panoramic bottom glass or other suitable transparency (optics), transparent material, below the waterline allowing passengers to observe the underwater environment from within the boat. The view through the glass bottom is better than simply looking into the water from above, because one does not have to look through optics, optically erratic surface disturbances. The effect is similar to that achieved by a diving mask, while the passengers are able to stay dry and out of the water. Use Glass-bottom boats are used for giving tours, as they are usually designed to allow the maximum number of tourists to view out the glass floor, glass bottom. Glass-bottom boats are in use in many seaside tourist destinations as well as lake towns. Typical tours in these boats include views of underwater flora and fauna, reefs, shipwrecks, and other underwater sights. History The glass-bottom boat was invented in 1878 by two men, Hullam Jo ...

Biological Contamination
Biology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, origin, evolution, and distribution of life. Central to biology are five fundamental themes: the cell as the basic unit of life, genes and heredity as the basis of inheritance, evolution as the driver of biological diversity, energy transformation for sustaining life processes, and the maintenance of internal stability ( homeostasis). Biology examines life across multiple levels of organization, from molecules and cells to organisms, populations, and ecosystems. Subdisciplines include molecular biology, physiology, ecology, evolutionary biology, developmental biology, and systematics, among others. Each of these fields applies a range of methods to investigate biological phenomena, including observation, experimentation, and mathematical modeling. Modern biology is ...

Red Sea Clownfish
The Red Sea Clownfish (''Amphiprion bicinctus'', meaning "both sawlike with two stripes"), commonly known as the Red Sea or two-banded anemonefish is a marine fish belonging to the family Pomacentridae, the clownfishes and damselfishes. Like other species of the genus, the fish feeds on algae and zooplankton in the wild. Characteristics of Anemonefish Clownfish or anemonefish are fishes that, in the wild, form symbiotic mutualisms with sea anemones and are unaffected by the stinging tentacles of the host anemone, see . The sea anemone protects the clownfish from predators, as well as providing food through the scraps left from the anemone's meals and occasional dead anemone tentacles. In return, the clownfish defends the anemone from its predators, and parasites. Clownfish are small-sized, , and depending on species, they are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. Within species there may be color variations, most commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lionfish
''Pterois'' is a genus of venomous fish, venomous marine fish, commonly known as the lionfish, native to the Indo-Pacific. It is characterized by conspicuous aposematism, warning coloration with red or black bands and ostentatious dorsal fins tipped with venomous Spine (zoology), spines. ''Pterois radiata'', ''Pterois volitans'', and ''Pterois miles'' are the most commonly studied species in the genus. ''Pterois'' species are popular aquarium fish. ''P. volitans'' and ''P. miles'' are recent and significant invasive species in the west Atlantic, Caribbean Sea, and Mediterranean Sea. Taxonomy ''Pterois'' was described as a genus in 1817 by German natural history, naturalist, botany, botanist, biologist, and ornithology, ornithologist Lorenz Oken. In 1856, French naturalist Eugène Anselme Sébastien Léon Desmarest designated ''Scorpaena volitans'', which had been named by Marcus Elieser Bloch, Bloch in 1787 and which was the same as Linnaeus's 1758 ''Gasterosteus volitans'', as th ...

Vaccination
Vaccination is the administration of a vaccine to help the immune system develop immunity from a disease. Vaccines contain a microorganism or virus in a weakened, live or killed state, or proteins or toxins from the organism. In stimulating the body's Adaptive immune system, adaptive immunity, they help prevent sickness from an infectious disease. When a sufficiently large percentage of a population has been vaccinated, herd immunity results. Herd immunity protects those who may be immunocompromised and cannot get a vaccine because even a weakened version would harm them. The effectiveness of vaccination has been widely studied and verified. Vaccination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the Eradication of infectious diseases, worldwide eradication of smallpox and the elimination of diseases such as polio and tetanus from much of the world.

Spotted Eagle Ray
The spotted eagle ray (''Aetobatus narinari'') is a cartilaginous fish of the eagle ray family, Aetobatidae. As traditionally recognized, it is found globally in tropical regions, including the Atlantic, Pacific and Indian Oceans. Recent authorities have restricted it to the Atlantic (including the Caribbean and Gulf of Mexico) with other populations recognized as the ocellated eagle ray (''A. ocellatus'') and Pacific white-spotted eagle ray (''A. laticeps''). Spotted eagle rays are most commonly seen alone, but occasionally swim in groups. They are ovoviviparous, the female retaining the eggs then releasing the young as miniature versions of the parent. This ray can be identified by its dark dorsal surface covered in white spots or rings. Near the base of the ray's relatively long tail, just behind the pelvic fins, are several venomous, barbed stingers. Spotted eagle rays commonly feed on small fish and crustaceans, and will sometimes dig with their snouts to look for food bu ...

Green Sea Turtles
The green sea turtle (''Chelonia mydas''), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus ''Chelonia''. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, due to its diet strictly being seagrass, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of ''C. mydas'' is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, ''C. mydas'' is mostly herbivorous. The adults usually inhabit shal ...

Hawksbill Sea Turtle
The hawksbill sea turtle (''Eretmochelys imbricata'') is a critically endangered sea turtle belonging to the family Cheloniidae. It is the only extant species in the genus ''Eretmochelys''. The species has a global distribution that is largely limited to tropical and subtropical marine and estuary ecosystems. The appearance of the hawksbill is similar to that of other marine turtles. In general, it has a flattened body shape, a protective carapace, and flipper-like limbs, adapted for swimming in the open ocean. ''E. imbricata'' is easily distinguished from other sea turtles by its sharp, curving beak with prominent tomium, and the saw-like appearance of its shell margins. Hawksbill shells slightly change colors, depending on water temperature. While this turtle lives part of its life in the open ocean, it spends more time in shallow lagoons and coral reefs. The World Conservation Union, primarily as a result of human fishing practices, classifies ''E. imbricata'' as crit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrimp
A shrimp (: shrimp (American English, US) or shrimps (British English, UK)) is a crustacean with an elongated body and a primarily Aquatic locomotion, swimming mode of locomotion – typically Decapods belonging to the Caridea or Dendrobranchiata, although some Shrimp#Non-decapods, crustaceans outside of this order are also referred to as "shrimp". Any small crustacean may also be referred to as "shrimp", regardless of resemblance. More narrow definitions may be restricted to Caridea, to smaller species of either of the aforementioned groups, or only the Marine life, marine species. Under a broader definition, ''shrimp'' may be synonymous with prawn, covering stalk-eyed swimming crustaceans with long, narrow muscular tails (Abdomen#Arthropoda, abdomens), long whiskers (Antenna (biology), antennae), and slender, Biramous, biramous legs. They swim forward by paddling the swimmerets on the underside of their abdomens, although their escape response is typically repeated flicks wit ...

Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...
