Predators of The Sea

Here are my thoughts on predators of the sea

Tiger sharks are one of the most fascinating species of sharks, with a distinctive appearance and properties, and the alarming threat to humans. This beautiful aquatic creatures that live primarily in tropical, temperate climates, and are considered sacred in Hawaii. To protect species of shark conservation projects specifically focused on tiger sharks in use, and these creatures of the ocean are often the volunteer center for marine conservation.

Tiger sharks are a species very large shark, which grows at a frightening about 4 m long and weighing up to 635 kg. With this scale, it is not surprising that they constitute a threat to humans, especially because they like shallow water tropical disturbance. For the brave, however, those interested in the experience of marine conservation biology of these animals up close, free of cages or glass separates.

Hunt for Prey

Besides their assessment of a human will tasty tiger sharks eat almost anything, the conservation of sharks and workers do not focus on a lack of food for these mammals. As predators, their daily diet consists of small sharks, turtles, seals and other fish, and as hunters, they are excellent, they have the choice of the ocean. They are also excellent hunters and their ability to find and catch prey is impeccable. Their heightened senses mean that they can catch their prey with comparative ease. With their excellent eyesight, they can spot prey a mile away, even in troubled waters. And their sense of smell means that even a small amount of blood can feel very remote and are able to trace the unsuspecting victim. They also have the remarkable ability to collect frequency waves to low pressure, so they know when something moves and lives in nearby waters.

But they are also known for their inability to distinguish between what food and what is undesirable, and a number of elements of human waste were found in their stomachs. From plates to car wheel bike, these animals will eat almost anything. Thus, while lack of food in May did not include environmentalists tiger shark, is the pollution of the sea with garbage more disturbing.

Attacks on humans

Since the hunting abilities of large tiger sharks, they form a certain degree of risk to humans. In fact, they are responsible for a large percentage of fatal attacks on humans, one of the great white shark. While environmentalists and marine biology Hawaiians who believe that the tiger shark is too sacred to pursue the animal, bathers and tourists have a different opinion to keep! But it is important to keep in mind that tourist activities, such as Shark Cage Diving is also responsible for attracting sharks in shallow waters over populated, yet another problem for conservationists to address sharks

The Tsunami Warning Systen In Indonesia

Here are my thoughts on the tsunami warning system in Indonesia

Nobody in the current period will remember the 200,000 victims of the Indonesian tsunami, caused by the earthquake in Sumatra on Christmas Eve. But what is done in the region while still maintaining high seismic active volcanoes and earthquakes? The Pacific region needs to fire warning system, with the Indian Ocean, there are also seismic activity in the Caribbean and we consider here systems.

Indeed, there are some good things being done to save lives in another 200,000 people die, the next time there is not a tsunami or major earthquake, which triggered. Like the Japanese, Americans and some other countries are installing warning systems for tsunamis in the world, time is also important, most systems in place, the safer of the civilizations of the man by the water and there are problems now with volcanoes and some people will not leave because they believe that the volcano is safe passage for the final journey in life? And the volcanoes are an environmental nightmare for people and nature. Although some might say it's just cleaning up the earth so that it can start a new project and part of the cycle?

There are two hundred years of the 4 major earthquakes over 6 and 7 also. The region is very active seismic and tsunami alarm helps warn people of impending tsunami wave so that all people living in the time zone near the coast to evacuate. Consider this in 2006.

Cyclone Nargis

Here are my thoughts on the Cyclone Nargis.

Nargis formed into a tropical cyclone on April 27, 2008, in the central bay of Bengal about 360 miles off the southeast coast of India. Cyclone Nargis was, when they landed at the mouth of the Ayeyawaddy (Irrawaddy) River, about 220 km south-west of Rangoon, a category four storm on the Saffir-Simpson scale of hurricane, with sustained winds of 132 mph. Nargis is the deadliest cyclone to hit Asia since 1991, when 143,000 people died in Bangladesh from a cyclone in the country this year. The formation of Nargis in the Bay of Bengal coincides with the start of hurricane season in the northern Indian Ocean, which generally runs from April to December.

Burma hit by Nargis, is undergoing a natural disaster and human. As Nargis swept the Irrawaddy River delta, hitting the region with winds, storm surges and heavy rains, tens of thousands of lives lost. Burma is isolated from the rest of the world against the best times. The nature of the disaster, the vast area involved and the secrecy and mistrust of the Burmese government, it is impossible for an accurate account of the tragic loss of rights to obtain, but some are treasures of life lost in the hundreds of thousands, instead of dozens. This brings the disaster of Nargis on equal terms with the tsunami of Boxing Day 2004 killed 300,000 people.

Tropical storms are among the systems most powerful and destructive weather events on earth. They are a product of the interaction between the atmosphere and oceans. The pressure recorded in the centers of tropical cyclones are among the lowest that occur on the surface of the earth at sea level

Despite the long season, region, Bay of Bengal and the Arabian Sea, has averaged a little over five such storms per year, with only two full tropical cyclones. Tropical cyclones are compact, round of storms, generally some 320 km (200 miles) in diameter, whose winds revolve around a central area of low pressure. The winds are driven by the nucleus at low pressure and the rotation of the Earth, which deflects the path of the wind through a phenomenon known as the Coriolis force. As a result, tropical cyclones rotate in an anti-clock (or cyclones) direction in the northern hemisphere and a clockwise (or anticyclonic) direction in the Southern Hemisphere.

In the world's tropical cyclones were informally second given names of women in the Army U. S. Air Corp and Navy meteorologists (after their girlfriends or women) who were monitoring and forecasting of hurricanes on the Pacific Ocean. From 1950 to 1952, tropical cyclones of the North Atlantic Ocean were identified by the phonetic alphabet (Able-Baker-Charlie-etc. While a hurricane can generate strong winds and heavy rains, they are also able to produce high waves and storm surges harmful. Although their effects on human populations can be devastating, tropical cyclones can also relieve drought.

Tropical cyclones are known by different names in different parts of the world. In the Atlantic Ocean and North Pacific Ocean, north-east, they are called hurricanes, and the Pacific Northwest around the Philippines, Japan and China the storms are called typhoons. In the Western Pacific and Indian Oceans are alternately referred to as tropical cyclones, typhoons or simply cyclones. All these different names refer to the same type of storm.

With rising global temperatures adding energy to the weather systems on Earth there is a chance that storms across Nargis May be greater, once again the huge impact of the huge population of vulnerable coastal areas and Delta in the world.

Sea Pollution

Here are my thoughts about sea pollution.

Many wastes are disposed in the sea can cause a variety of acute and chronic health conditions. The concentration, biological form, chemical form, fitness and survival of these pollutants are all aspects of whether humans would be exposed to them. There are two ways in which humans can be contaminated by such pollution. The first is direct contact or through the skin, lungs, or to be consumed, swimming in contaminated seawater would be a good way to be infected by direct contact method. The second way is an indirect way, as the consumption of plants or animals coming from the infected area.

Indirect infection is an important way in which humans are exposed to toxic organic chemicals and metals because they can be built in bio plants and animals that humans consume. Direct contamination is a less important area where people can be exposed to toxic organic chemicals and metals because they tend to the low concentration in seawater.

Persistent 'conservative' and 'pollutants such as toxic metals and PCBs break down slowly in any case, while "not conservative' and 'labile' pollutants such as biodegradable or volatile organic compounds are rapidly degraded and removed from the area. The" conservative 'and' persistent 'pollutants are the most problematic because of its persistence in the environment increases their chances of reaching and affect humans.

There are three main categories of pollutants into the sea and that can have adverse effects on human health. Early toxic metals like arsenic, cadmium, lead and mercury, synthetic organic chemicals as polycyclic aromatic hydrocarbons (PAHs), chlorinated hydrocarbons, pesticides (PCBs), specialty chemicals biphynyls biphenyls (PCBs) and the third human pathogens such as viruses, bacteria, fungi and parasites.

Metals are chemical elements and can not be destroyed, broken or degenerated in the environment. Toxic metals are deposited on the sea have impacts on human health, especially arsenic, cadmium, lead and mercury. These four metals are of particular interest because they are known to be toxic to human health and are found in high concentrations in the estuaries of rivers and the sea. Chromium, selenium and copper were found in concentrations of less, but still worrying because in areas in contact with people. Consumption of contaminated fish is the main route of indirect exposure to toxic metals. Marine organisms such as fish, crabs and shellfish bio accumulate these toxic metals through their gills to swim and feed on the infected subject. Arsenic, cadmium, lead and mercury can cause acute and chronic illnesses such as gastro-intestinal bleeding, Comas, liver and nerve damage, skin and lung cancer, emphysema, anemia, kidney, liver, pancreas damage, damage to bones, blood disorders, reproductive disorders, eye damage, respiratory and skin lesions.

Organic chemicals used in industry, these chemicals used in pesticides, cosmetics, pharmaceuticals and food additives. The behavior of these chemicals in natural environments ranging from accumulation of organisms that decomposes rapidly when exposed to light, heat or water to be very resilient and are metabolized by other organisms in more or less toxic compounds to the resistance against bio - degradation. Like toxic metals, organic chemicals have direct and indirect routes to human health from direct contact with organic chemicals and indirectly by ingestion of infected animals and plants. The route of direct contact is rare at sea, only organic chemicals in low concentrations, this method is not a bad effect on human health due to low concentrations. Again, as with toxic metals the indirect route of consuming contaminated seafood could be most harmful to human health. Chlorobenzenes, chlorinated pesticides, chlorinated hydrocarbons and aromatic hydrocarbons are found in seafood. These chemicals all adverse effects on human health, including causing cancer, skin and liver disorders.

Human pathogens are micro-organisms capable of inducing human diseases. Human pathogens enter the sea from the discharge of wastewater, sewage and wastewater treatment plant effluent. Pathogens are also found in commercial food waste and animal waste and organic household waste from hospitals and laboratories. Many of these pathogens are discharged to surface water or wastewater treatment plants. In rural areas, bacterial contamination from animal waste, runoff and poorly treated sewage discharge. De zee zelf is een bron van ziektekiemen die zich voordoen en verspreiden van nature in mariene wateren. Viruses and bacteria are the main waste-borne agents of human disease with respect to the concentration in the waste and the environment and the diseases they cause. Both direct and indirect exposure of humans are important aspects of human health effects. This is because only a small number of agencies are needed to cause illness. Evidence has shown that some bacteria, including known human pathogens can survive at sea for up to three months. Many parasites and viruses are very resistant to environmental destruction. Many human pathogens seem better in coastal or estuary areas of open sea survival. Large parts of the coastal waters and estuaries in the U.S. are closed shell fishing because of pollution by sewage micro-organisms. Seafood-borne bacterial diseases have been responsible for typhoid, paratyphoid, cholera and viral gastroenteritis outbreaks in the U.S.. Some diseases such as typhoid bacteria contracted by swimming or surfing in water that is contaminated with sewage. Many divers are affected by conditions such as dermatitis, wound infections and enteric diseases.

Basic Info About Octopus

Here are my thoughts about octopus.

The octopus is a mollusk. He belongs to the same group as chitons, abalone, snails, barnacles, mussels, oysters, clams and mussels. The octopus belongs to a sub-species of cephalopod molluscs, as known. This means head to toe and is used as the name for an octopus "feet" to be attached to the head.

Polyps tend to be small in warm tropical waters and larger in colder waters. Squids live in all oceans, but are strictly salt-water creatures. The Giant Pacific Octopus lives in the coastal waters of British Columbia and is the largest octopus in the world. The largest Giant Pacific Octopus more than 600 pounds, about the same weight of a black bear weighed caught! The tentacles of an animal stretched upwards of 33 feet in length. Obviously the octopus are generally much smaller. For example, women are rarely more than 55 pounds and males average less than 90 the giant Pacific octopus is one of the species lived longer, while the majority of octopuses live only one or two years. The male can reach up to about 4 years and females can live for up to 3.5 years.

An octopus has eight arms attached to their heads around the mouth. The "poor" are rows of suckers along their length. They are equipped with suction cups on the surface and within the nerves of many, which means that both are packaged and "taste" were things. How, for example, the giant Pacific Octopus has two rows of suckers on each arm with suction cups 1600 in all.

One of the striking things about an octopus that is has absolutely no bones. The only rigid anatomical structure and a beak, the mouth, the material is made with the nails. By the way, octopus bites are poisonous to their prey.

The octopus has an excellent and well-developed brain. You can immediately adjust the color and texture of the skin in the area. This mimicry is an important tool of protection.

The body of the octopus looks like a lot. Moves as the octopus breathes. Inside (the body), mantle, there are 3 heart, stomach and other organs. A heart that pumps blood through the individual Gill, at the end of each of the two annexes, while the third pumps blood through the body. Water flows over the gills and fills the mantle when the octopus breathes, the water is forced through a tube called the siphon as the octopus breathes. E 'can force the water through the siphon jet is fast and tries to return, when the octopus to escape a predator too. With jet engines, Octopus travel many kilometers. An octopus can protect temporarily blind an attacker to inject ink it.

The Dangers Of Sea Life

Here are my thoughts on the dangers of sea life.

Sometimes they even float on the surface. Most marine life that is harmless. Some should be avoided whenever possible.

Sharks are a concern and popular shark attacks can happen. But, statistically, are rare unless you go to where the water travels are throwing chum to attract sharks. Most SeaLife meet is less lethal but far more common and some are still inflict painful wounds.

Portuguese Man-o'-War jellyfish and similar species are probably the most common problem for surfers. They are difficult to detect and easily provoked to bite. The bite injects a toxin through a painful bite with a tab on the end. The results of the pain can be severe, lasting from minutes to hours of agony.

If you see them, if possible. Unlike most animals, there are efforts to prevent human beings, at least not the efforts are generally successful. They are accustomed to using their attributes to paralyze the prey.

If you contact, try removing the jelly as soon as possible. If this is the whole animal, which sometimes can be excluded from your arm or leg, or a part that is broken. Remove any stinger as quickly as possible. The more the animal is in contact, the toxin that you are getting.

Remove at once can result in a few minutes of intense discomfort. At a certain dose, the toxin that causes pain in the lymph glands, usually in the armpits. This is an experience you never want to have. Last May several hours.

The races are less common in many areas, but occur in some places to surf. They have a tail that contains a spiny protrusion. They are less likely to strike and are more difficult to provoke, but the contact can be painful or even lethal. Although it was a rare incident, the famous animal scientist, Steve Irwin, the Crocodile Hunter, died when he was stabbed in the chest by a stingray.

There are other sedentary marine creatures, which can cause discomfort, disorientation or injury.

Coral reefs are alive with all sorts of prickly creatures, raw, and others that produce abrasions and cuts. Few are poisonous, but most are painful to swim. If your card works in a shallow area in which the feet or legs are in contact with a reef is likely to be beaten.

Exercise common sense, wear a wetsuit if you plan to be in an area that contains SeaLife dangerous, and not for trouble. You have more time for surfing.

Wear a bathing suit in the sun and swimwear UV protection when outdoors, surfing or swimming, since the sun's UV rays can reflect on many surfaces and causes damage to the skin.
