?What is the largest invertebrate animals

The Animal Kingdom The animal kingdom comprises millions of living organisms, which are divided into two main sections: vertebrates and invertebrates. This kingdom is made up of all eukaryotes, multicellular organisms, and all living organisms in the animal kingdom rely on other organisms for their food; that is, they are not self-feeding. A total of 800,000 different species were identified in 36 divisions, including the Birds, Mammals, Reptiles, Fish, Amphibians and all of these vertebrates. Invertebrates include sponges, stings, worms, mollusks, arthropods, and skin lice. [1] ADVERTISING INRED INVENTED BY TEDES The largest invertebrate species is the largest and largest invertebrate animals ever known and the most weighty in the world. Although these organisms were known only from a few dead parts (because of the severe difficulty of holding them), scientists have managed to capture a number of them over the past years. They can not be controlled directly because of the deep depths in which they live, but scientists believe - from the study of their samples - that they catch their prey with ambiguity, taking advantage of its bright members that attract the attention of fish and other organisms deep in the sea to approach and then break them. ] Scientists have known the existence of giant squid for the first time since 1925, when they began to discover the remains and parts of his body in the whales of the giant amber whale, but it was not possible to see a giant giant squid (even dead) until 2003, when it was possible to catch it for the first time In a depth of more than 2000 meters below the surface of the water, and was 10 meters long, and weighing more than 500 kg, and therefore it has become the largest animal evergreen known to humans at all. [3] Invertebrates Invertebrates are all types of animals belonging to the Kingdom of animals and not in the body structure An internal bone or a spine. It represents the vast majority of all living things on the planet. Scientists estimate that they are between 15 and 30 million species, which is 90% or more of all animals. These creatures live all over the world; their existence is documented even in the deepest caves, in the oceanic depths of more than 10,000 meters, in the upper layers of the atmosphere, in the most arid deserts and in the coldest and most arid regions, 35 C. Invertebrates are found in a wide variety of shapes, species and sizes, but they are generally small in size compared to vertebrates; their land sizes range from less than one millimeter (making their visibility impossible), and even a meter to two meters. The group of invertebrates consists of small organisms in nature, including insects, spiders, caterpillars, worms, and scorpions. They also include many aquatic organisms, such as crabs, octopuses, gourds, jellyfish, sponges, etc. [4] Many vertebrates have a relatively solid external structure that helps protect their bodies, but they may also be slow-moving and small in size because of their lack of spines and skeletons. Her lack of bones. Invertebrates have no sophisticated respiratory equipment; they have no lungs, but absorb air through the skin. Most species of invertebrates have organic tissues, although most species are able to move, but some do not have this ability, such as sponge that sticks to the seabed throughout life. [5] Classification of invertebrate animals Invertebrate animals are divided into several groups, One of which is Phylum. These groups are the supreme and fundamental divisions of the kingdom of animals. There is no complete scientific agreement on the number of these divisions. As the science evolves, the animal kingdom is continually divided into a new people or a people But in total, there are about 20 to 30 divisions of the animal population. In all their classification, vertebrates (including fish, reptiles, amphibians and mammals) have only one division, all of which belong to different invertebrates The most common groups of invertebrates commonly known to people are insects, which fall within the division of arthropods, with a population of about one million species, as well as molluscs (which include octopuses, binders, and claws) of approximately 85,000 species. Crustaceans The largest group of invertebrates at all and the most diverse, organisms whose body consists of joints and a solid external structure to protect its bodies, and its bodies are divided into three parts , Are the head, chest, abdomen, many live in water. Arthropods include many of the most important invertebrate groups, including all insects, spiders (including ticks), crustaceans (including crabs, shrimp), scorpions, and legs (forty-four). [5] Mollusks are the second largest group of invertebrates, It is characterized by its unpartitioned and soft-limbed bodies and has a thin outer shield to protect it.
