Characteristics of Dolphins
The majority of small tooth whales are called dolphins. “Dolphins are mammals of the order Cetacean and the families Plantanistidae and Delphinidae and include about 50 species” (Internet 1). Most dolphin species are about 6 feet in length, the males averaging 4 to 8 inches longer than females. The longest dolphin, the bottle-nose dolphin, can reach over nine-feet in length and weight up to 440 pounds. The smallest dolphin species is the buffalo which is found in the Amazon River. The Buffalo dolphin rarely grows over 3.9 feet or weighs more than 66 pounds.
A dolphin’s diet consists mainly of herring, mackerel, and sardines. “Some species however, prefer squid, shrimp and other crustacean” (Gygax 585). The average amount of fish ingested is estimated at about 66 pounds a day for an individual dolphin about 8.2 feet and 220 pounds.
The body of a dolphin is sleek, smooth and hairless, making the skin rubbery to the touch. Most species have jaws that protrude into a beak like snout. “Above the upper jaw is a large mass of fat and oil-containing tissue forming the so-called "melon" that looks much like a bulging forehead” (Internet 1). The dorsal fin on the mid-back of the dolphin contains the skeletal remnants of five digits that form the flippers. Dolphins use the dorsal fin primarily as stabilizers, although occasionally in an oar like fashion. The dorsal fin is formed from subcutaneous dermal tissue and is not movable by muscle action. The hind flippers consist of a pair of small pelvic bones, deeply embedded in the connective tissue at the base of the tail. The caudal, or tail, fin is also primarily dermal in origin, rather than skeletal, and con...

Orca whales are the largest members of the dolphin family. Orcas are very curious creatures, they like to sky hop, which is when they poke their heads out of the water and look around, and they can also dive to as much as a hundred feet. These social animals live in pods and stay with them for their whole lives. They are so family oriented that they can may sleep together in a tight circle and have synchronized breathing. Orcas can grow up to thirty-two feet and can weigh nine tons. They typically eat five percent of their body weight and are amazing hunters. The lifespan of an orca in their natural habitat is about fifty years. This lifestyle for them is wonderful because they can swim as far as they want to and are free. Orcas should not be held captive because the capture process is dangerous, it is not good for their health, and their trainers are at risk. Free Willy. Dir Simon Wincer. 1993.Video.

Orcas, or killer whales are majestic giants of the sea. They are actually the largest type of dolphin. They have long black bodies with distinct white patches near their eyes. A killer whale can be up to 32 feet or more in length, and weigh up to 12,000 pounds. Females are a bit smaller, but live longer (Gorman). The name “killer whale” apparently came not because it is a vicious whale, but because it preys on whales. They do not have any natural predators, and they are considered the “top dog” of the ocean. Not even the great white shark stands a chance against these superb killers. “Unlike sharks, killer whales are cautious hunters, sometimes spending hours harassing a 1,000-pound sea lion so it can easily be drowned” (Francis). Orcas use many hunting tactics that are unique to their species, which is what makes them invincible.
As seen in examples of monogatari such as Tales of Ise or nikki with The Tosa Diary, poetry is a very much used tool in the writings. While other examples of the two writing styles use poetry, these two examples best demonstrate the breaks in the writing style changes from a narrative and turns into something that takes on a more personal voice when it clearly goes into its poetic style. These poems are made to compliment the setting, such as in a poem credited to the former governor in The Tosa Diary where there is a description of the waves as they illustrate the governor’s sadness as he leaves Kyoto (83). Another point seen from this poem is that the governor is meant to be very good at constructing his poems and with it comes an example of a good poem as opposed to something that a commoner would have to write. Likewise, in the tenth of the Tales of Ise there are poems describing the love a man has for a woman while he is also comparing the physical setting, such as the mountains. There are comparisons to Mt. Fuji and Mt. Utsu while they represent the waiting for his love or the beautiful vision that the man sees in his dreams with his love respectively (75-6). Such images of the scenery as seen alongside the desires or longing of those who write the poems are examples of how the poems are used to strengthen the narrative prose. Without the poems, the narrative prose in either the monogatari or the nikki would simply be a story and the significance would be lessened as there would not be the personal impact emanating from the characters and their feelings since a reader would only be able to read the description of the events and not get a feel of the thoughts from any of the characters.
Lady Macbeth was “choked with ambition”. Her infatuation to be queen is the single feature that Shakespeare developed far beyond that of her counterpart in the historical story he used as his source. Lady Macbeth persistently taunts her husband for his lack of courage, even though we know of his bloody deeds on the battlefield. At this point in time, with all her will converging towards seizing the throne, she has shown no signs of remorse or hesitance in her actions and hence preventing the events in the narrative from digressing away from imperative themes and climaxes of the play.
Such sea life as shrimp, squid, small sharks, other vertebrates and fish are all a part of a Bottle-nosed dolphins diet. When they find a large school of fish, several schools of dolphins join up to form groups of up to 1000 dolphins. They work together to head and catch the fish. Another feeding method the Bottle-nosed dolphin has developed is chasing the fish on to mud banks and snaps them in the air.
During the late nineteenth and early twentieth century, the United States was the most dominant power in the Western Hemisphere. European nations conceded to the United States their right of any intervention in the Western Hemisphere and allowed the United States to do whatever they wanted. The United States took this newly bestowed power and abused it. The United States intervened in many Latin American countries and imposed their policies on to these countries against their will. A perfect example of this aggression is what occurred in the Dominican Republic in 1904. The United States intervened in this sovereign nation and took control of their economy and custom houses. A memorandum from Francis B. Loomis, the United States Assistant Secretary of State, to the Secretary of States illustrates the United States’ goals, interests, attitudes and assumptions in the Dominican Republic and how the United States policy makers felt towards Latin America during this time period.
Lady Macbeth is at the same time greater and lesser than her husband. She has a hardness which he lacks, but she has none of his subtlety and perception. She knows her husband well and despises him a little, but to satisfy her ambition, which is a crude desire to see her man King, she will devote herself soul and body to evil. (62)
...llent imitators. Imitation ability was tested at the dolphin institute; two bottlenose dolphins each had their own trainer and could see the other dolphin, but not the other dolphin’s trainer. Trainers then gave commands to the dolphins. In this experiment, it was found that dolphins, despite not being able to see the trainer, could successfully imitate another dolphin’s behavior after that dolphin was given a command from its trainer (TDI 2012). Additionally, dolphins could imitate human movements after associating analogous parts of their body with human parts. For example, the dolphin raised its tail when its trainer raised her leg (TDI 2012). The ability for dolphins to successfully imitate another dolphin’s behavior suggests that dolphins have learning abilities, giving further insight and a better understanding of social structures of the dolphin community.
One of Lady Macbeth’s commonly overlooked traits is her goodness, especially towards her husband, Macbeth. This goodness is first apparent at her introduction; as she reads the letter written to her by Macbeth. The letter tells of the three witches, whom Macbeth refers to as the weird sisters, and a prophecy regarding Macbeth’s future kingship. Immediately, Lady Macbeth desires the throne for her husband. Not only desire is felt, but also determination. Worried that Macbeth would not be capable of walking the quickest path to the throne, killing the current King Duncan, Lady Macbeth calls forth evil spirits to strip her of her weaker, feminine qualities. She says:
By the 1750's, the industrial Revolution had begun. At first, inventions were strictly limited to cotton weaving. Inventions such as the spinning jenny and the water-powered frame, both of which provided spinning yarn faster, the spinning mule, the power loom and the cotton gin, all helped the manufacture of cotton goods by speeding up the process. Mass production had begun, along with capitalism. Capitalist, people who have their own materials, money and space, bought many machines and stored them in a factory, where hired people worked the whole day manufacturing goods. The factory system had replaced the cottage industry. Mass production made usually expensive items, such as shoes, less expensive and easily affordable by lower class and less wealthy people.
... Craigie, and Gunn, 2010). Second, address factors that place the child at risk such as a lack of parent involvement. Third, directly address children’s risk through early child hood education amongst other things. There are also policy changes that can be implemented with regard to mothers’ economic plights and the resources available to them. There should be a strengthening of community based programs that aid mothers and a focus on them working efficiently (Kalil & Ryan, 2010). Safety nets provided in the form of things such as food stamps need to be strengthened as well. Policies should support these resources and have an ultimate goal of economic self sufficiency for mothers in fragile families. The issues presented allow policy makers to be well informed of the possible risks associate with fragile families and the issues they face, especially economically.

The Industrial Revolution was the main contributor of the development of factories and modern day machinery. The Industrial Revolution created hundreds of new jobs, influenced many new inventions, and created many new ways of creating and transporting goods. Many jobs including spinners, miners, factory workers, and farmers were beginning to rise in population, due to the new technology being created in the 18th and 19th centuries. The start of new inventions coming into view was beginning in Britain, with many agricultural tools creating new ways to plow and yield crops. Later on, it caused new forms of transportation to be developed, for example, railroads and canals. This essay will explain exactly how these causes began, and how they prospered in the Industrial Revolution.
One of the biggest industries during the Industrial Revolution was textiles. Many women and children made pants, shirts, socks, bedspreads, and other items by their tiny hands and fingers with cloth. With the population growing in England, more people were willing to pay for these items instead of making the items themselves. This started to lead to a new factory system. With “cotton becoming the world’s most imp...
There are many reasons why dolphins are very intelligent animals, there are 33 different types of marine dolphins, 4 types of river dolphins, and 6 types of porpoises (dolphins are mammals). Some of the dolphinspeople may think they would be whales, because of their looks, but they are dolphins. Dolphins have a strong behavior; they are very social and travel in groups together. They commonly swim in groups of 2-15 . Severalof different groups of dolphins may temporarily join, for several minutes or hours. In the open waters of theocean, some dolphins will leave their group and change associates and adapt with different dolphins threw outtime (Dolphins communication). In the groups, some members will form a strong bond with one another in thepod. The sizes of the groups tend to increase with the water depth of the ocean and the openness of the habitat, this usually happens when protection with strong with each other and foraging st...
