known diving cetaceans is the sperm whale (Physeter macrocephalus). The world’s largest carnivore, this massive cetacean makes extremely deep dives for food, mainly squid and octopus, but also fish and sometimes giant squid (Burnie and Wilson 2005). Sperm whales can dive to depths of 400 to 1200 meters, and for durations of up to 138 minutes (Watwood et al. 2006). The majority of sperm whale dives have been reported to last from 33 to 53 minutes (2006). Sperm whales have to overcome several fundamental
eighty-five ton sperm whale miles deep out in the ocean. In these times, going on any ocean expedition had its precautions. While much focus on food, drinking water, medication and a method to cure illness, the most overlooked impairment was the creatures of the ocean. While the men of this vessel left the docks as predators, the survivors of the ninety- three-day journey on three small harpoon boats came back as prey. This story gives a great depiction of the potential of the sperm whale as well as
In Herman Melville’s world-renowned tale, Moby Dick, the crew aboard the Pequod sail the seas in order to hunt, capture, and kill a mysteriously terrifying sperm whale named “Moby Dick”. For centuries, humans have used technological advances to protect their elite status in the animal kingdom, at the unfortunate expense of species ignorantly perceived as being too weak or unintelligent to fight back.

whiteness of the whale as many things, including “grand or gracious” and that “no man can deny that in its profoundest idealized significance it calls up a peculiar apparition to the soul.” (Melville 172) Ishmael ultimately concludes that the reason we are afraid of whiteness is because it represents things that are both beautiful and terrifying - an indefinite void that makes us think of atheism, nothingness, the absence of color, etc. This sort of thinking in Chapter 42 about the whale is abstract and
can guarantee me that I will not be attacked by a shark. I do believe when the Palumbis say that sharks are not the deadliest animals in the water, but I believe sharks probably pose the most danger to me, compared to the cone snail, giant squid, sperm whale, or sailfish.

century classic MOBY DICK, due to the reason that Herman Melville had written his famous novel MOBY DICK after inspiring the real life event of Whaleship Essex. In the heart of the sea is the story of a Whaleship Essex that was attacked by a bull Sperm Whale almost 85 feet in length. This attack destroys and sinks the ship, stranding the crew in three whaleboats. The crew managed to salvage some provisions and some water and the quick thinking of the steward also helped them to save some navigational
In the Heart of the Sea What caused an 85 ton Sperm whale to crash into the side of the Essex, causing one of the most disastrous and tragic accidents in maritime history? Was this a calculated attack? Did it see the whaling ship as an unwanted rival in its territory? Did the crew of the Essex have anything to do with the whales’ sporadic behavior? Or was this simply an unexplainable act of nature’s unpredictability? On November 20, 1820 the crew of the Essex spotted an unusual sight, an extremely
Ishmael marvels at this site from the Pequod, and on the second day paints the picture of “Right Whales” mowing through the brit, “leaving behind them endless swaths of blue upon the yellow sea” (Melville, 1851: 305). The meadow‑like appearance of the sea is truly a realistic one, however, the comparison is embellished in such a farfetched, illusory
the Hand, is illustrative of this. Melville writes, "I squeezed that sperm till a strange sort of insanity came over me; and I found myself unwittingly squeezing my co-laborers' hands in it, mistaking their hands for the gentle globules. Such an abounding, affectionate, friendly, loving feeling did this avocation beget; that at last I was continually squeezing their hands, and looking up into their eyes" (322-323). The word "sperm" is short for spermatozoon, a mature male reproductive cell. The word
themselves. The relationship between cat and mouse is the apotheosis ot this idea, a classic case of one preying on the other where the two are looked upon as complete opposites. In Herman Melville's "Moby Dick" the whalers are hunting down the white whale. So according to my statement above this should make the crew members of the "Pequod" the absolute negation of Moby Dick. At first glance, maybe it seems this way, but in actuality the two are very similar. From the moment the crew members choose to
Humpback Whales Humpback whales are amazing mammals and they go through a lot of extraordinary things to be able to survive. There are many whales in the ocean, but the whales that are in the Hawaiian culture areas have many difficulties and most people don't understand why. Humpback whales have the scientific name of Megaptera Novaeangliae, that species of baleen whale is one of the larger species, and adults range in length from twelve to sixteen metres which is thirty to fifty-two feet. They
not completing the equal separation resulting in two fetuses fused together in some way, and half-twins or polar body twins, which are made when an unfertilized ovum splits into two complete, identical parts and is then fertilized by two different sperm. The frequency of identical twins is 3.5 per 100 births (1) and the frequency of conjoined twins is 1 birth per 50,000 with only 100 known cases surviving their first year (5). There is no scientific explanation for why an ovum splits into two or
glands. Male sperm carries genetic information and are produced continually from the start of puberty. The primary spermatocyte divides by meiosis make two secondary spermatocytes and then four, which have half the amount of chromosomes as the mother cell (46 in humans) therefore sperm (spermatozoa) has 23 chromosomes (genetic information). Sperm produced in the testes in a sac called the scrotum is 3°C cooler than normal body temperature as they hang down between the legs. Sperm does not
simple lab test on rats, scientists were able to disable the taste receptors to see if it would have any major impact on them. In attempting to breed rats that did not have functioning taste receptors on the testicles, scientists discovered that the sperm was rendered deformed and unable to fertilize, making the rats infertile. The drug that researchers used to block these taste receptors was the same kind of drugs that are used to treat high cholesterol in humans. This discovery can help scientists
states how it is done. To do this, scientists measure DNA in sperm cells and pass the millions of them through a tiny tube in a single file. They then separate the “girl sperm” from the “boy sperm”. They can tell the difference because “girl sperm” has more DNA. The separated sperm cells are then used, one or the other, to impregnate a woman to have a girl or a boy. In a study, fifteen out of seventeen women with the “girl sperm” had girls. Getting the Girl by Lisa Bellkin, an article in the

The most active and healthy sperm are selected by forcing them to swim through a culture medium. - The egg and sperm are placed together in a suitable medium for fertilisation to occur in a culture dish. If fertilisation does not occur after 72 hours, the oocytes (incompletely developed eggs) and sperm are disposed of. The resulting embryos are observed for the next few days. - A small plastic tube is inserted through
BIRTH AND CREATION: One of the main issues in the novel, and also in Victor Frankenstein's mind. One of the reasons for creating his monster, Frankenstein was challenging nature's law of creation. That is, to create a being, male sperm and female egg must be united etc.. He was also fraught with the mystery of death and the life cycle. He created something in defiance of our understanding of birth and creation. However the similarity of Frankenstein's creation and a baby's creation is that both need

People often question whether or not cloning is morally acceptable in our society, and also if it is worth all the money that we spend on research for cloning. It is hard to believe that not to long ago many people believed that joining a sperm and an egg in a test tube was considered to be morally wrong. It is now used by millions of doctors around the world. Cloning is at the beginning stages of being considered morally unacceptable and will soon move to be just like in-vitro fertilization
