Life of Octopus Dofleini
Introduction
This is a research report on octopuses in general, however will focus in on a particular species of octopus, the North Pacific Giant or octopus dofleini , which is a bottom dwelling octopus that lives on coasts of the pacific ocean, from California to north Japan. This report will cover the habitat, and lifestyle of this amazing mollusk, that is so often misunderstood. The octopus is a very intelligent, and resourceful invertebrate whose natural abilities should make this a fairly interesting reading.
REPRODUCTION OF O. DOFLEINI
The spawning of the giant pacific may occur at any time of the year, however the mating of the octopus peaks in the winter months, with the peak of egg laying in April and may. Octopuses reproduce sexually, and have both male and female octopuses. Reproduction takes place as follows: The male octopus uses his tentacle to take a mass of spermatophore from within his mantle cavity, he then inserts it into the oviduct, in the mantle cavity of the female. This process occurs at depths from 20-100m and, lasts hours. With female octopuses receiving spermatophore up to 1m long.
Female octopus seem to prefer larger males as mates and male octopus may mate with more than one female in their life span, however the male octopus only lives a few months after breeding, and the female will die shortly after the eggs hatch.
Incubation can take from 150 days to seven or more months. The female may produce any where from 20,000 to 100,000 eggs over a period of several days.
During incubation the female octopus will take to cleaning and aerating the eggs.
This takes place at a depth of less than 50 meters
LIFE SPAN OF O.DOFLEINI
After hatching, the baby octopus (or larvae) take on the role of plankton, drifting around the ocean feeding on neuston (dead food) as opposed to hunting live prey. This stage on an average lasts for 30-90 days.
Without mating the octopus may survive up to five years, and Giant
Pacific octopus have been found to reach a weight of 600 pounds, and an estimated width of over 31 feet, But the average size is only 100 pounds and 3m, still weighing in as the largest species of octopus.
During their life span, many octopus fall victim to fatal, and non-fatal predation. Therefore a high percentage of octopus are mutilated or missing arms, this percentage increases in octopus that live in deep water, perhaps this is because older octopus tend to occupy deeper waters and would naturally have more battle scars. However larger octopus are less prone to these injuries.
... Bipolar Support Alliance conducted a research study that indicated more than 2.5 million people suffer from Bipolar, also known as Manic Depression (Fawcett 3). The many faces of this illness is treated and stabilized with various types of medication and therapy. Furthermore, the family of the patient most likely will benefit from seeking therapy in their effort to help the patient with stabilization and living with this illness. All involved in the patient’s life is valuable in this process. Strategies for recovery include medication, visits with psychiatrists and other medical providers as needed, psychotherapy and support from family. These strategies can help people live with this illness affectively. No matter the type, Bipolar is a sickness and should be looked at and treated as such. People are much more than their illness and should be treated accordingly.
...to 300 individuals, the newborn seahorses are independent of parental care and the male is free to fertilize and accept more eggs(Lourie 11). The offspring bearing roles displayed by Hippocampus spp. is an extreme shift in relation to many other species of kingdom Animalia, of which the bearing of young is predominantly carried out by females. According to Foster, growth rates throughout the life cycle and the duration of the life cycle of seahorses in the wild varies between species and cannot be determined due to insufficient research data(foster 22). Once sexual maturity is reached, often determined by the presence of a brood pouch in males, adults are able to reproduce. During reproduction, the overwhelming majority of Hippocampus species display monogamous behaviors, usually mating with the same partner for the duration of the mating cycle(lourie 10-11).

At the turn of the century, American readers were interested only in stories with happy endings, where goodness was praised and evil was punished. They did not particularly care if that was a false interpretation of the way life really was. When men such as Frank Norris, the author of The Octopus, wrote angrily of the injustices and poverty to be found in America, readers turned away. The Octopus made them change their minds. The course of the novel and the reality of its characters held the readers’ attention. It is so powerful a book that people had to care about the wheat growers, almost against their wishes.
Healthcare professionals want only to provide the best care and comfort for their patients. In today’s world, advances in healthcare and medicine have made their task of doing so much easier, allowing previously lethal diseases to be diagnosed and treated with proficiency and speed. A majority of people in the United States have health insurance and enjoy the luxury of convenient, easy to access health care services, with annual checkups, preventative care, and their own personal doctor ready to diagnose and provide treatment for even the most trivial of symptoms. Many of these people could not imagine living a day without the assurance that, when needed, medical care would not be available to themselves and their loved ones. However, millions of American citizens currently live under these unimaginable conditions, going day to day without the security of frequent checkups, prescription medicine, or preventative medicines that could prevent future complications in their health. Now with the rising unemployment rates due to the current global recession, even more Americans are becoming uninsured, and the flaws in the United States’ current healthcare system are being exposed. In order to amend these flaws, some are looking to make small changes to fix the current healthcare system, while others look to make sweeping changes and remodel the system completely, favoring a more socialized, universal type of healthcare system. Although it is certain that change is needed, universal healthcare is not the miracle cure that will solve the systems current ailments. Universal healthcare should not be allowed to take form in America as it is a menace to the capitalist principle of a free market, threatens to put a stranglehold on for-...
Like almost any other animal the octopus has many dangers that they need to hide from. Octopuses are masters of camouflage and have amazing defensive skills that can be used for fighting. Octopi are known for defending themselves against small sharks and other dangerous predators. An octopus uses its color changing abilities to blend in with its surroundings and to warn other animals to prevent them from attacking the octopus.
In recent years, the number of Americans who are uninsured has reached over 45 million citizens, with millions more who only have the very basic of insurance, effectively under insured. With the growing budget cuts to medicaid and the decreasing amount of employers cutting back on their health insurance options, more and more americans are put into positions with poor health care or no access to it at all. At the heart of the issue stems two roots, one concerning the morality of universal health care and the other concerning the economic effects. Many believe that health care reform at a national level is impossible or impractical, and so for too long now our citizens have stood by as our flawed health-care system has transformed into an unfixable mess. The good that universal healthcare would bring to our nation far outweighs the bad, however, so, sooner rather than later, it is important for us to strive towards a society where all people have access to healthcare.

It is also an issue that affects almost everyone in our great nation. The reasons for and against a Universal Health Care are many and both sides can make justified arguments. Over the last few decades, the United States has witnessed skyrocketing health care costs. Health insurance premiums have been rising on average by double-digit percentage points and even more recently, a rate of increase that is 2-3 times the rate of inflation. Because of these out-of-control health care costs, there has been a steep rise in the number of uninsured Americans. Currently, more than 45 million Americans lack any form of health insurance, and millions more have insurance, but lack adequate financial protection from health care costs. Many in the USA believe that a universal health care system would bring about changes that would improve the quality of life for everyone, but my purpose for writing this essay was not to make mind-blowing suggesting on how to create a universal health care system that is accessible across all the United States. That I will leave for the policy experts to figure out. My goal here was to simply show why this is a public issue and why it is so important that we pay close attention to the conversation about a universal health care system in the US because it really does, affect every one
Bipolar Disorder is a serious and complicated mood disorder characterized by abnormal fluctuations between an individual’s high and low moods. Mania, Depression, Hypomania and Mixed Episodes are the predominant moods that can be identified in the different forms of Bipolar Disorder (GlaxoSmithKlein, 2007). The etiology, symptomology, and treatment for each mood and form of Bipolar Disorder vary as well. Moods can be identified by a person’s level of happiness, sadness, outlook on life and how he may physically feel (Mondimore, 2006). Patients struggling with Bipolar Disorder have difficulty regulating the euphoric highs of mania, the “black hole” feelings of depression, the “softer side” of hypomania and the incessant cycling of Mixed Episodes. With so many different forms of this mood disorder, Bipolar Disorder can be difficult to recognize and treat.
Males are usually larger than females, but there are no obvious physical differences that mark their sexes. There is only one very slight difference in the pattern of scales in front of the cloaca. Though it is difficult for researchers to identify the sexes, the Komodos seem to have no trouble. They mate between the months of May and August. The female lays about 30 eggs and the incubation cycle is roughly 9 months (Benyus, 1992).
In conclusion, unfortunately this mental illness doesn’t disappear. Though Bipolar Disorder is a long term mental illness, they are treatments that can suppress the severity that will, in turn, aid the patient to live a more mentally stable life. The only support as a family member is standing by their side and never turning your back on them. It is a serious illness that affects the individual making it difficult to live each day with.

Have you ever wanted to slap eight people at once? Or if you're more of a mushy, touchy, feely person, have you ever wanted to hug eight people at once? An octopus can do either or both of these if they want to! So you know an octopus is lucky being able to do this but what's an octopuses habitat? Since they can slap eight things at once do they have predators? Or since we're on the facty facts subject where do they live?
Building self-esteem, enhancing student satisfaction with the learning experience, and promoting a positive attitude toward the subject matter are all benefits of collaborative learning. A higher degree of accomplishment takes place as a group because you essentially are a team. An example of this is a sports team. In a collaborative situation it takes every member to do his or her part in order for a situation to have a greater resolution; as where a sports team needs everybody’s individual talent to win a game. In retrospect, as a group; the contributions of our own talents can make the difference between a “win or Lose situation” it gives you a sense of competition, and knowing that you can win as a group; self esteem in one’s self is accentuated. Johnson and Johnson (1989), Slavin (1967). Another benefit to collaborative learning is based on the members of your group. Every individual in the group demonstrates their own input based on where they were born, what nationality they are so on and so on. The benefit of this is that you get a different perspective on things rather than always knowing what you know. You can take information from other cultures and add or apply it to what you already know.
