Arthropods Phylloph Arthropoda is one of the important animal kingdoms of the kingdom. It belongs to more than 75% of the vertebrate animal kingdom, the animals that have a joint in the legs, and also have shields similar to solid external structures, such as pods, chitins, and shells. The animal's body consists of several sections. Some of these animals have a pair of legs in each section of their body that they use to live with the environment, such as walking and swimming, including three pairs of legs. Nutrition Arthropods are classified in terms of nutrition to the following: Single platelets, which are arthropods classified as pastoral, are taken from the minutes and small substances to feed them, which are less than many platelets, and the arthropods with the legs of the legs are predatory, Take the damaged items for her food. Molluscs, the ones that feed on algae, are also sometimes pastoral, get their food by having a strong oral mass, and have long teeth and long intestines. The division of arthropods is divided into several groups, including: Class Crustacea: This group includes a large number of animals with more than 52 thousand species, and include invertebrates within the crustaceans, crustaceans have a solid external structure that provides protection for the body, and is an alternative to Skeletons, and crustaceans settle large bodies of water, such as the seas and oceans, and the most prominent types of crabs, prawns, bronchillas and others. (Myriapoda): It is one of the orthopedic arthropods, and the individual members of these Shoaiba have a large number of legs, and classified these Shuaiba to: Centipede, and a thousand men, and small legs, and the collections, and extinct. Hexagecia: Six-legged organisms join Shuaiba arthropods. Spiders are also called spiders. Scorpions and spiders are submerged. Shuaiba is classified into a terrestrial and aqueous species, and it is divided into more than 100,000 species. The spiders have eight legs and lack centuries of sensors and wings. Characteristics of arthropods The Division of arthropods consists of different species in terms of place of living as aquatic and terrestrial. Animals are described as three-layered. The members of the arthropod division are characterized by repetitive rationality. The articular animals have double angles, including strong mandibles. It has a solid external structure to protect its body. Dislocations are a method of growth and development, passing through a series of stages of growth between each of the two periods of disintegration. Her muscles are marked as planned. It has an oral supra-temporal contract in its nervous system that connects the ventricle and the mental contract. Enjoy excellent evolutionary devices. The body cavity of the arthropods consists of a bloody thrombosis and a thoracic heart. Its body is divided into three main parts: the head, the chest, and the abdomen. Breathing methods vary according to the environment in which you live. The water arthropods breathe through gills. It has an output device consisting of tubular tubes
