    بحث عمل الطالبة / رضا عبد السلام (2-3) / Introduction to marine organisms

    مُساهمة من طرف Roully Fadel

    Introduction to marine organisms in general:
    Increased attention to marine organisms and to increase the benefit in terms of food, medical, and also for the prevention of
    Evils. The marine bio-diversity of large and not easy to restrict or even classified because it has many special features And ways of life, as well as a variety of different and Apprenticeship members and methods Tzaugea and reproduction. Some marine organisms Draw oxygen through the gills and some of these animals breathing through the lung and that his rise to the surface to renew the air.There are fish prefer to live close to the surface or deep, medium-and there are fish prefer the dark bottom. It was scientists believe that there is any living because of the presence of oxygen, but removed the submarineJapanese a lot of secrets and the discovery of a huge life in the abyss with pictures and analysis of samples. Has been discovered that there is in the depths where no oxygen living environment integrated system of other
    The life of these objects is based on extracting energy from the decomposition of hydrogen gas Kbritoz abroad The ground that this new discovery astounded scientists. Although difficult to classify these sea creatures will divide into different groups in
    Major characteristics are as follow

    - Plant and animal plankton

    - Fish

    - Molluscs

    - Crustaceans

    - Mammals

    - Amphibians.


    Marine invertebrates
    Is a group of marine animals without a backbone or skeleton, and also lack the advanced features and sophisticated in fish and marine mammals (vertebrates). And exercise all the activities that characterize the organism, such as nutrition, movement and reproduction, and this family has many types, most colorful, including sponges, soft and hard corals, jellyfish, and sea anemone (Anemone), and the helicopter as well as worms, molluscs, crustaceans, animals Guenvvep skin.


    Sponges
    Simple primitive animals are made up of a number of cells among the conjunctiva, and is located in the sea attached to rocks or other solid materials such as boats or columns of buried oil wells in the sea. Water is flowing into the sea sponges constantly through minute holes scattered all over the body, and thus absorb the oxygen needed for respiration and nutrition of animal and plant plankton microscopic (plankton), and the waste water rushes out through the barrel of the other, sponges and take many forms, colors and different sizes, some of which may grow to more than meters.


    Algeoffmaouiat
    Belong to this group different animals shapes and complexions, bright colors like conjoined plants rocks and striking, which marine animals live individually or in the huge colonies, and the basic structure of these animals lies in the central abdominal cavity serves as the gastrointestinal tract is called (polyp), and feed on microscopic plankton (plankton), where you Albollieat Tentacles provided by cells of extensive hand paid and is absorbed by plankton from the water into the polyp, and is disposed of waste through the same cavity. This group includes sea anemone (Anemone) and jellyfish, soft corals and steel. All of which are suitable for breeding in ponds, taking into account the food requirements of its own. This group is divided into three communities are:
    First: a range of animals Agrip Includes animals be solitary or live in colonies, and the most important examples (Aloobelya) is an animal Hdri stick to rocks or marine plants alone between the tides and have large colonies. Are breeding here in two ways, one to Ajnci (budding) and the second phase and sexual composition of the so-called average (Almidozp).

    Second: a Alphenjaniat
    These include the community jellyfish (s) of all kinds, animals that rely primarily on the movement of waves and sea currents to transport them from one place to another. The prominent phase in these animals is called (Almidozp), a dislike usually like a parachute, and Gelatini strength in diameter in most species between 7 - 30 cm or more in some types of other gelatinous umbrella hanging from a large number of feelers vary in length according to type, and these feelers with cells to cause large poisonous wounds and a severe infection of the skin. There are different types of which are fatal to humans (such as Box-jellyfish) found in Australia may extend its umbrella and tentacles to several meters, and the grace of God Almighty, these species do not exist in the Arabian Gulf.

    Third: a Alcaaiat
    These include community to the sea anemone (Anemone) types, and coral reefs, soft pink, and coral reefs solid. The sea anemone lives mostly individual, their body is composed of flesh and gelatinous polyps in the form of rigid cylindrical, consisting of the base, trunk or leg, oral disc, surrounded Bloams bearing cells used to hunt large prey or in defense of itself, and some species such as live fish Alqaiss the Clown, interdependence of life with the Sisters Navy. And can be breeding and multiplication of these radicals in the marine basins to provide food and lighting appropriate to them. The soft pink corals, are usually located in deep water far from shore are different kinds and shapes and colors, some take the form of sticks covered with soft velvet fabric stand out from the polyps of different colors, others see it as if the branches of trees and plants are intertwined with each other, and have supported the central structures Bcoikat limestone, including coral helicopters (Georgonyan) and black coral (ease) Alcgeri shape and strength of horns often. Can be grown in ponds taking into account the requirements of food and to provide appropriate lighting to it. And hard corals, each of the screening Boulibadtha soft calcium carbonate to form the backbone of steel, and various forms of the coral reefs are a huge colonies, huge numbers of these polyps. And live and grow coral in shallow marine waters and relatively warm, and pure Inhjb not by the light of the sun with the availability of food, and coral reefs are one of the most productive and diverse environments in all shapes, colors, and where the majority of marine fish and invertebrates. And can be breeding and multiplication of many types of these maraging in ponds Algmaiio taking into account the requirements and provide suitable lighting.




    Marine worms
    These worms are divided into two divisions: the cyclins and the Division Mufltahat all of the ingredients are basic food for large numbers of fish, crustaceans and other invertebrates, play a major role in the process of natural balance in the marine environment. There is no doubt the worms is the helicopter of the most beautiful species of these worms, and their bodies be protected horny flexible tube is usually buried in the silt and sand, and has a color mock withdrawn into the tube whenever it feels threatened.
    Some types suitable for breeding in ponds, taking into account the food requirements of their own.



    Crustaceans
    Crustacean family consists of many kinds, characterized by their Borgelha arthropods and limestone structures of Foreign Affairs, and the crustaceans in the stages of growth to replace the outer structure of a new structure once every three months. And assume the head usually, two centuries sensors sense and search for food. The most important of these crustaceans: Asertaniat Navy (Alkabbaqub) and shrimp mother shrimp. Some of these species suitable for breeding in aquariums, but Alkabbaqub WAM shrimp will prey on small fish.
