Swordfish Habitat, Behavior, and Diet

Swordfish (Xiphias gladius) was made famous in the late 1990s by Sebastian Jungers book The Perfect Storm, which was about a swordfishing boat lost at sea. The book was later made into a movie. Swordfishing captain and author Linda Greenlaw also popularized swordfishing in her book The Hungry Ocean. Swordfish is a popular seafood that may be served as steaks and sashimi. Swordfish populations in U.S. waters are said to be rebounding after heavy management on a fishery that once overfished swordfish and also resulted in a large bycatch of  sea turtles. Swordfish Identification These large fish, which are also known as the broadbill or broadbill swordfish, have a distinctive pointed, sword-like upper jaw that is over 2 feet long. This sword, which has a flattened oval shape, is used to stab prey. Their genus  Xiphias comes from the Greek word xiphos, which means sword. Swordfish have a brownish-black back and light underside. They have a tall first dorsal fin and distinctly forked tail. They can grow to a maximum length of over 14 feet and weight of 1,400 pounds. Females are larger than males. While young swordfish have spines and small teeth, adults do not have scales nor teeth. They are among the fastest fish in the ocean and are capable of speeds of 60 mph when leaping. Classification Kingdom: AnimaliaPhylum: ChordataSubphylum: VertebrataSuperclass: GnathostomaSuperclass: PiscesClass: ActinopterygiiOrder: PerciformesFamily: XiphiidaeGenus: XiphiasSpecies: gladius Habitat and Distribution Swordfish are found in tropical and temperate waters in the Atlantic, Pacific and Indian Oceans between the latitudes of 60 °N to 45 °S. These animals migrate to cooler waters in the summer, and to warmer waters in the winter. Swordfish may be seen at the surface and in deeper waters. They can swim in deep, cold parts of the ocean due to specialized tissue in their head that warms their brain. Feeding Swordfish feed primarily on small bony fish and cephalopods. They opportunistically feed throughout the water column, taking prey at the surface, in the middle of the water column and at the ocean bottom. They may use their sails to herd fish. Swordfish appear to swallow smaller prey whole, while larger prey is slashed with the sword. Reproduction Reproduction occurs by spawning, with males and females releasing sperm and eggs into the water near the ocean surface. A female may release millions of eggs, which are then fertilized in the water by a males sperm. The timing of spawning in swordfish depends upon where they live - it may either be year-round (in warmer waters) or during the summer (in cooler waters). The young are about .16 inch long when they hatch, and their upper jaw becomes more noticeably longer when the larvae are about .5 inch long. The young dont begin to develop the sailfishs characteristic elongated jaw until they are about 1/4 inch long. The dorsal fin in young swordfish stretches the length of the fishs body and eventually develops into a large first dorsal fin and a second smaller dorsal fin. Swordfish are estimated to reach maturity at 5 years and have a lifespan of about 15 years. Conservation Swordfish are caught by both commercial and recreational fishermen, and fisheries exist in the Atlantic, Pacific, and Indian Oceans. They are a popular game fish and seafood, although mothers, pregnant women, and young children may want to limit consumption due to the potential for a high methylmercury content. Swordfish are listed as of least concern on the IUCN Red List, as many swordfish stocks (except for those in the Mediterranean Sea) are stable, rebuilding, and/or being adequately managed.

Australian And International Legal Systems - 1347 Words

Human rights are the recognition of basic rights and freedoms believed to justifiably belong to all human beings. When studying human rights for indigenous Australians now it is vital to also consider this issue in an historical context. The profound injustices since white settlement have left deep scars which are ever present today. The new settlers followed the legal approach that the land was not â€Å"owned† before white settlement (Terra Nullius, meaning â€Å"nobody’s land†) and therefore was theirs for the taking. They not only inflicted systematic physical and mental abuse but they fenced Indigenous Australians out of their land, which had and has an impact that is difficult for non-indigenous Australians to comprehend. In evaluating both Australian and International legal systems and how effective they have been in addressing justice for our indigenous people, the starting document is the Australian Constitution. Our Constitution conspicuously fails to recognize the rights of Australia’s indigenous peoples. No indigenous Australians were involved in the development of the Constitution. In the 20th Century indigenous Australian children were forcibly removed from their families under Acts of both Federal and State governments. This practice occurred between approximately 1905 and 1969. These Acts of Parliament were clearly discriminatory and created what became known as â€Å"the stolen generation†.

Reasons for Attending College or University Free Essays

Reasons for Attending College or University Summary:Â  People attend college or university for many different reasons, such as new experiences, career preparation, and increased knowledge. Many people attend colleges and universities all over the world to study and conduct research. What are their expectations of the academic experience? In my opinion, people involved in collegiate programs have two main purposes: to gain the experiences and certificates that prepare them for future careers and to increase their knowledge about different aspects of life. We will write a custom essay sample on Reasons for Attending College or University or any similar topic only for you Order Now Many people desire stable careers that deeply affect their lives. Therefore, good preparation for a future career is a necessity. To maintain and promote your position at a company, especially in certain kinds of jobs, you must have the knowledge and experiences that come from attending a college or university. The skills, spirit, and confidence you gain from studying help equip you for your work. Moreover, it is easier to find a good job when you have qualified certificates. Many well-educated people can carry out their tasks smoothly and methodically with more economization of time and strength than people who manage their work by learning from their failures. Another advantage of attending a college or university is the relationships you build with other people. These relationships help you improve yourself. In a collegiate environment, you learn how to work in groups and how to cooperate with your partners. You also learn to achieve mutual understanding, an essential and useful skill in your future work. The second reason for attending a college or university, increasing knowledge about many aspects of life, might seem a little impractical, but it is, in fact, very practical. Some people have the misconception that studying in college provides them only with knowledge relating directly to their major and that getting certificates is the most important purpose of attending college. With those goals in mind, they often neglect subjects that don’t seem to be applicable to their work. However, knowledge from college is not just useful for your job; it also is useful for many other things in life. For example, people with basic knowledge about literature, history, art, psychology, etc. might enjoy their lives more than unlearned people. They also might overcome difficulties and stress more easily, as well as have an acceptable and optimistic attitude toward obstacles and failures in their lives. Furthermore, cultivated people might treat others in their communities with more regard. Nothing you study in college is useless, and increasing knowledge is as important as getting certificates. The more knowledge you have, the more poetic your life is. Generally speaking, it’s always necessary to have a good education. In addition to obtaining the appropriate certificates, attending a college or university gives you a great opportunity to learn about many different things on both macroscopic and microscopic levels. While the specific reasons people attend colleges and universities might differ, the fundamental purposes are the same: they want to obtain the necessary training and education for their future careers and they want to learn about a variety of different subjects that will apply to their lives outside their future careers. Therefore, everyone who chooses to attend a college or university should always strive to reach their goals and aspirations.

Othello 2 free essay sample

Othello # 8211 ; Iago Hates The Moor Essay, Research Paper Iago has a big appetency for retaliation. In his position, he believes that it is he who should be in charge, non Othello the Moor. This creates an choler in Iago, who entraps Othello in a web of fraudulence. He does this through a series of suggestions and vacillations that entice and implant images in Othello # 8217 ; s head that lead to his death. But what is more of import is that he gives Othello the motivation to slay guiltless Desdemona. Iago is invariably like a marionette maestro, drawing the strings of the people around him. There are many cases in the drama where Iago is left by himself. He utilises these chances by stating his hereafter programs to the audience. It would seen that he likes speaking to himself about himself, which suggests he has much interior convulsion that he harbors near to his thorax, but when the chance arises, he describes his workss with a passion. We will write a custom essay sample on Othello 2 or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the first of these soliloquies, he makes his purposes absolutely clear. He implies that Othello has had an matter with his married woman by saying # 8220 ; I hate the Moor, And it is thought abroad that # 8216 ; twixt my sheets He # 8217 ; s done my office # 8221 ; . The sarcasm of this statement is that in the following line he says that he does non cognize it for a fact, but because he suspects it, he will move as if for certain! This gives me the feeling from the beginning, that Iago is insane and extremely paranoid, traveling so far as to put up a cache of slayings, merely on the intuition of criminal conversation. Iago was besides covetous of the unfastened and loving relationship that Othello had. When Othello and Desdemona are reunited after the journey to Cyprus, he kisses her in full position of everyone. Iago dainties his married woman as an object and she knows it. In Act three, Scene four, she tells Desdemona â€Å"They are but stomachs, we are but nutrient, and when they are full, they belch us† . In Iagos # 8217 ; racialist head, he views his superior, Othello, as being of an inferior credo. He sees him as possessing an evil head and psyche, and holding no right to get married the really white and really naif Desdemona. He does non even think of Othello as a human being, but as an animate being. This can be seen when he shouts to Brabantio # 8220 ; An old black random-access memory is tupping your white Ewe # 8230 ; you # 8217 ; ll have your nephews neigh to you ; you # 8217 ; ll have coursers for cousins, and jennies for Germans # 8221 ; . Iago besides has a hatred of Cassio, who was given the publicity that Iago idea of as his ain. To acquire his requital, he envelopes Cassio in his retribution secret plan so that he can have the rubric of lieutenant after his shame. Iago is a really cute adult male. He plays the characters in the narrative like a game of cheat. He uses his assorted pawns to make the dirty work so as to destruct the general and his married woman. The worst of these is when he tells Emilia to steal the hankie, because when she finds out what it was used for, she feels responsible for Desdemona # 8217 ; s decease. From scene to scene he is ever in the company of a different individual, distributing his prevarications further and further. He acts as a baronial individual, and everyone thinks of Iago as their ally. He uses every chance possible to make a feeling of misgiving, so that everyone is paranoid. Bing a maestro of misrepresentation, this was non hard. He manages to run successfully, until Emilia his married woman, unknot his sinister program but it is already excessively tardily, as Desdemona is dead and Iago has gained his retaliation from Othello.
