American Lobster Facts

American Lobster Facts Some think of lobster as a bright red delicacy served up with a side of butter. The American lobster (often called the Maine lobster), while a popular seafood, is also a fascinating animal with a complex life. Lobsters have been described as aggressive, territorial, and cannibalistic, but you may be surprised to know theyve also been referred to as tender lovers. The American lobster (Homarus americanus) is one of about 75 species of lobsters worldwide. The American lobster is a clawed lobster, versus the spiny, clawless lobster that is common in warmer waters. The American lobster is a well-known marine species and is easily recognizable from its two hefty claws down to its fan-like tail. Appearance: American lobsters are generally a reddish-brown or greenish color, although there are occasionally unusual colors, including blue, yellow, orange or even white. American lobsters can be up to 3 feet long and weigh up to 40 pounds. Lobsters have a hard carapace. The shell does not grow, so the only way the lobster can increase its size is by molting, a vulnerable time in which it hides, shrinks and withdraws from its shell, and then its new shell hardens over a couple months. One very noticeable feature of the lobster is its very strong tail, which it can use to propel itself backwards. Lobsters can be very aggressive animals, and fight with other lobsters for shelter, food and mates. Lobsters are highly territorial and establish a hierarchy of dominance within the community of lobsters that live around them. Classification: Kingdom: Animalia Phylum: Arthropoda SuperClass: Crustacea Class: Malacostraca Order: Decapoda Family: Nephropidae Genus: Homarus Species: americanus American lobsters are in the phylum Arthropoda, which means they are related to insects, shrimp, crabs and barnacles. Arthropods have jointed appendages and a hard exoskeleton (outer shell). Feeding: Lobsters were once thought to be scavengers, but recent studies have revealed a preference for live prey, including fish, crustaceans and mollusks. Lobsters have two claws - a larger crusher claw, and a smaller ripper claw (also known as the cutter, pincher, or seizer claw). Males have larger claws than females of the same size. Reproduction and Life Cycle: Mating occurs after the female molts. Lobsters display a complex courtship/mating ritual, in which the female picks a male to mate with and approaches his cave-like shelter, where she produces a pheromone and wafts it in his direction. The male and female then engage in a boxing ritual, and the female enters the males den, where she eventually molts and they mate before the females new shell hardens. For detailed descriptions of a lobsters mating ritual, see the Lobster Conservancy or the Gulf of Maine Research Institute. The female carries 7,000-80,000 eggs under her abdomen for 9-11 months before larvae are hatched. The larvae have three planktonic stages during which they are found at the waters surface, and then they settle to the bottom where they remain for the rest of their lives. Lobsters reach adulthood after 5-8 years, but it takes about 6-7 years for a lobster to reach the edible size of 1 pound. It is thought that American lobsters can live for 50-100 years or more. Habitat and Distribution: The American lobster is found in the North Atlantic Ocean from Labrador, Canada, to North Carolina. Lobsters can be found both in coastal areas and offshore along the continental shelf. Some lobsters may migrate from offshore areas during the winter and spring to inshore areas during the summer and fall, while others are long-shore migrants, traveling up and down the coast. According to the University of New Hampshire, one of these migrants traveled 398 nautical miles (458 miles) over 3 1/2 years. Lobster In the Colonies: Some accounts, such as that in Mark Kurlanskys book say that early New Englanders did not want to eat lobsters, even though the waters were so rich in lobsters that they were literally crawling out of the sea and piling up inhospitably on the beaches. (p. 69) It was said that lobsters were considered a food fit only for poor. Evidently New Englanders eventually developed a taste for it. In addition to harvesting, lobsters are threatened by pollutants in the water, which can accumulate in their tissues. Lobsters in highly-populated coastal areas are also prone to shell rot or shell burn disease, which results in dark holes burned into the shell. Coastal areas are important nursery areas for young lobsters, and young lobsters could be affected as the coast is developed more heavily and population, pollution and sewage runoff increases. Lobsters Today and Conservation: The lobsters biggest predator is humans, who have seen lobster as a luxury food item for years. Lobstering has increased greatly over the last 50 years. According to the Atlantic States Marine Fisheries Commission, lobster landings increased from 25 million pounds in the 1940s and 1950s to 88 million pounds in 2005. Lobster populations are considered stable throughout much of New England, but there has been a decrease in catch in Southern New England. References and Further Information ASMFC. 2009.

Comparison Between Two political parties in Chile (PPD; PS) essays

Comparison Between Two political parties in Chile (PPD; PS) essays This project is based upon comparing two contemporary parties to each other, and then to the parties of Chile in the XIXth century. But before one can start to study this aspect, they must answer the question: "What is a political party?" By dictionary definition, the reply is: "An established political group organized to promote and support its principles and candidates for public office." We agree with this statement. A party is a gathering of people to promote their ideals and wishes in the government. Every party has it's leader and members, and is constantly in a battle to achieve presidency over the country. To do this they must gather support fom the people, oftentimes presenting them with statements that say that the people's wishes will come true, should the party rise to power. This incentive, of course, makes people vote. This project begins by analyzing both parties, in all their aspects; and then goes on to compare them to each other. Finally, we compare these parties to the parties in XIXth century Chile. Description of the Parties Being Compared The main principle of this party is to employ all forms of socialism in all aspects of society; maintaining that they have upheld socialism for all of their existence. They state that capitalism is a vile way of ruling a country; that it places "egotistical and separatist" thoughts in the minds of the people who they govern. This party aims to use democracy as a method of uniting all the aspects of society, to give them all a fair right to speak. They quote: "La democracia, para los socialistas, es el sistema polà ­tico que debe asegurar la convivencia entre los diversos componentes de la sociedad e inducir, por tanto, al desarrollo de los valores de la solidaridad y de la participacin ciudadana en todas las esferas de la vida social." This party claims that the economy of Chile is quite inneficient. According to their figures, for every 5% increase in produ...

Freedom in Various Aspects of Life Essay Example | Topics and Well Written Essays - 1250 words

Freedom in Various Aspects of Life - Essay Example This volume consists of over 274 authors and works that offer a variety of issues for analysis ranging from freedom to democracy to the changing times and everything in between! To begin with, the paper will define freedom. From there, it will take random features that have been strongly asserted in individual works of literature from the said volume in order to meet various objectives. The first of these will be to see the changing character of freedom and what it has meant at different time periods throughout history. This volume assists the author in doing so by presenting the works of authors and writers from various periods throughout history. Another objective will be to study the parameters within which the ways of defining and obtaining freedom have been portrayed by the various authors and their work within this volume. Further, this paper will seek to draw of the conclusion of how important freedom really is in the context of the works that have been studied from the volume . The interesting part about defining freedom is the fact that it has no definition per se. Freedom means different things to different people as well as different periods of time and history. In modern times it has meant freedom of expression and before that, for many people and their countries, freedom from oppression, colonization and various other such factors. In today's world, it depicts the freedom to choose peace and your own leader. Freedom, in a nutshell, is an expression of what a person, a nation, a society and other such entities, really want from life. The French Revolution was an upheaval that was marked by the formal birth of what we call nationalism. This has been demonstrated by the work contained on the Romantic Period within the volume. The authors here have used a variety of themes to showcase the period including the French Revolution, Women's Rights in the 18th century, the Gothic and many others. Spanning over a decade (1789 to 1799), this Revolution had a strong socio-political dimension to it as far as writing goes. This may be seen in the work titled "Democracy" by Thomas Carlyle. In this work, the embodiment of nationalism in various revolutions arose as a matter of its ability to define the elements that would support the construction of a democratic society free of feudal patterns. This was described in context of the citizens from every quarter of the French society, who wanted to break free of the double standards that were being imposed on their way of life in the form of the Church's intervention and the dictato rship of the aristocratic class. In the book, the revolution was an eye opener for the rest of world as regards rights and duties that must be equally distributed among the citizens of a nation irrespective of religion or socio-economic standing. This in itself was a new definition of nationalism and freedom, where earlier the same concept had been seen as a word that was used to describe the national character through its history and artistic work. By virtue of being a social movement, the French Revolution contributed greatly to the formation of a systematic body of knowledge known as nationalism. This is owing to the fact that a social movement is one that is punctuated with a highly idealistic environment with realistic parameters that set the stage for immediate results and the emergence of future trends that will go onto dominate the structure and functioning of that particular society for generations to come.

Some Antivirus program will not knowing by the policy assessment before make it own policy when it install in the computer system. There are three major types of detection which is used to identify the potential threats in the computer system such as: Signature based, Heuristic based File emulation method. Signature based detection: In this method, you can identify the viruses malware virus software. Antivirus software can also compare the content files of the computer system to dictionary files of virus signatures because viruses are embed into themselves in the files shape or in pieces shape to infect the computers. Heuristic based detection: In this method, you can only detect malicious activity relative to viruses identify unknown viruses in the computer system. File emulation: In this method, it has using the heuristic type approach which it executing the program in a virtual environment which effect the action of the program performs it also carries out the disinfection actions relative to the programs which run in the computer. What is a Virus?

Gimpel :: Essays Papers

Gimpel In the short stories ‘Gimpel the Fool† and â€Å"Death of a Traveling Salesman† we meet two characters that are vastly different and yet very similar. One is Gimpel, a naà ¯ve Jew living in Russia that is the joke of the town, Frampol. The other is R.J. Bowman, a traveling salesman, who is judgmental and rather suspicious about most things. Bowman in the story is very sick and has had a car accident where he needs to retrieve his car from a ditch and receives help from a couple that lives in the area. The two are very similar in that they both change in personality, Bowman becomes less cynical and suspicious by being helped, while Gimpel becomes much less naà ¯ve by being neglected and mistreated. Gimpel is portrayed by Singer as a role model, while is sharp contrast Welty depicts Bowman as the opposite, who realizes his inequities too late. In the Gimpel story, Singer presents the main character in a fashion that the reader is very sympathetic for him. The stereo typical â€Å"nerd†, an outcast that is rejected society. Gimpel is troubled by the hecklers that antagonize him and often seeks help. â€Å"I went to the rabbi to get some advice. He said, â€Å"It is written, better to be a fool all your days than for one hour be evil.† (Singer 197) The rabbis are the only ones in the story who don’t deceive Gimpel. Gimpel is forced into a marriage to with Elka a sinful woman, with a nasty mouth. â€Å"They were afraid to start anything with Elka. Her mouth would open as if it were on a hinge, and she had a fierce tongue.† (Singer 197) Gimpel is quite aware of her notoriety. â€Å"I cried, â€Å"you’re wasting your time. I’ll never marry that whore.† Gimpel sees marriage as an escape in being the town’s joke so he weds Elka. He loves Elka though she neglects him and cheats on him his love stands. This is a possible allusion to the book of Hosea. His character is also evident in the fact that he loves children that he knows are not his. Though he is treated bad he is still thankful for his family, showing his humbleness. â€Å"†¦I am a man, the husband of a fine wife, the father of promising children.
