The Giant Pacific Octopus

The Giant Pacific devilfish This paper is about manta ray dofleni, which is a behind-d easilying gray whale that kick the buckets on coasts of the Pacific ocean, from Northern Japan to California. This essay willing provide a draft overview of its sustenance, habits and opposite char characterizationeristics of this, intelligent and creative invertebrate and member of the Octopodidae family. The life of the pacific giant etiolatedthorn begin at any time of the year. The mating season however tends to peak in the month of December, with intimately of their eggs being laid in April and May. octopuses reproduction is sexual and takes positioning in the fewwhat shallow depths of 25 -100m and displace last hours.The dressing process begins with the male octopus, he uses his third right tentacle which has no suckers exclusively a modified structure known as the hectocotylus to pass spermatophore from in spite of appearance his servicemantle cavity into the the mantle ca vity of the female, also known as the oviduct. Male octopuses may mate with more than one female in their lifetime and females tend have a preference of bigger males for their mates. while the female lives until the eggs have time to hatch, the male dies only a few months after breeding. Reproduction afterward being fertilized the female will close herself take in a retreat here she will lay anywhere mingled with 20,000 and 100,000 eggs over a span of 2-3 weeks. Incubation can take from six to octet months. During this time the female octopus will take to cleaning algae and bacteria off the eggs as well as blowing water at them to keep a tight supply of oxygen. After the eggs hatch, the mother clears an opening in the den for her young to swim up to the surface of the ocean. Life Span After hatching the octopus larva become much like plankton, drifting along the surface of the ocean feeding on particles of dead food from other big(p) animals.This stage lasts 30-90 days at w hich point the octopus descends to the bottom of the ocean where it will spend the rest of its life. The Pacific giant may live up to five years without mating. close to have been put down weighing up to 600 pounds and being 31 feet wide, but the average coat is only about 9 feet wide and 100 pounds in weight, chill out weighing in as the largest species of octopus. The Den of the Octopus When making or finding a den, octopuses be very resourceful, some dig up argonas of sea floor to build their own den, but others prefer to live in manmade dens such as sunken ships.Dens are very all important(predicate) to octopuses, they use them for hatching their eggs, feeding, and sometimes uses it to hide from predators such as larger octopuses and seals. In general, octopuses are very mobile, and may occupy multiple dens in their lifetime. Feeding Habits Octopuses feed on everything from smaller octopus, crustaceans, crabs, and shrimp. Octopuses usually hunt at night and capture their course in many different ways, some use their brute strength and size while others poisonous substance prey with their venom.Lifestyle and Characteristics Much like the other aspects of its life, the octopus is very resourceful, in its defensive structure and hunting methods and mechanisms. Some species of octopus are extremely poisonous to man they can administer their poison in two ways, by either biting with their bird like beaks, or releasing the venom into the skirt water of its prey. Though octopuses usually use this tool for hunting, and not defense, this poison can attack the nervous, and respiratory systems of man and can cause termination within an hour.There is currently no known antivenom for the octopuss noisome poison. Octopuses also have the ability to change the color of their skin in order to camouflage themselves. This is done through the use of chromatophore cells in the skin. Chromatophore cells are comprised of three sacks containing different colors. The octopus can adjust these colors to have-to doe with the color of their background. The normal color of the octopus is brown, but it is also seen in other colors correlating with their emotions, such as red for anger and white for fear.The skin of the octopus is generally very soft, the only part that is not is the beak or the head of the octopus, this allows octopuses to fit through holes no larger than the beak its self. All octopuses have the ability to shoot out a jet of purple or blackish sign like precarious from under their eyeball, in order to per build a disappearing act when they feel threatened. The octopus can shoot out several blotches of this liquid before the fluid sac is emptied. This trick is not always an option, the ink is actually toxic to the octopus, and if shot in a confined area, the octopus will become sick or even die.Octopuses have slightly good eyes, in fact they are comparable to ours in clarity. The eyes of the octopus differ from ours, in the aspe ct that they focus by touching in, and out while the human eye works by changing the shape and size of the lens itself. The octopus also posseses the most sophisticated brain of all invertebrates, with both short, and long term memories. This allows the octopus to regard in much the same way as humans, through running play and error. When an octopus learns a lesson it remembers and puts its knowledge to use in the future.The octopus has eight spikes, with 250 suckers on each arm for a total of 2000 suckers on their body. These suckers are very sensitive to touch, in fact, the octopus can differentiate between different objects just as well with their suckers as they can with their eyes. Some species have particular suckers that are larger than the rest This is to aid in reproduction. Although octopuses often lose arms to predators, it is of no consequence as the arm will grow back in a short time. The Octopus Dolfeni and Man The pacific giant is the most common commercial speci es of octopus and is caught by fisheries from north Japan to Washington state.The octopuses are caught in large sometimes clay pots and raised to the surface. The octopuses are used for bait and for economic consumption by humans. Although these octopuses are caught in nearly all of their habitats, they are not endangered. The ocean is where life began, and is a far more competitive, and harsher manhood than the world we know. So it comes as no surprise that the most advanced and well adapted life forms would be found in the ocean. Although octopuses do not build large structured civilizations, they are obviously another form of intelligent and highly adapted life forms.
