Introduction to documents: chapter v: basic knowledge of animal classification i, biological boundary ii, basic knowledge of animal taxonomy iii, main taxonomy i, and biological boundary natural matter are divided into two broad categories: biological and abiotic. Biologicals are life phenomena with metabolism, self-replicating reproduction, growth and development, genetic variability, sensitivity and adaptability. Thus, the biological world is also known as the world of life (vivicum). There is currently no consensus on the biological boundary. The carlvon linne, 1735 age: the animalia botanical community (plantae) distinguishes organisms mainly by the characteristics observed in the eye, and the ability of organisms to move is the criterion: hogg, 1860 and haeckel, 1866). When the animal microscope of the botanical community (protista) is widely used, many single-cell organisms with animal and plant properties (e. G. Eye worms) are found to be evidence of evolution but are difficult to classify. : cobbran (,1938): the original nuclear community (protoctista) (including single algae, simple multicellular algae, fungi, fungi and protozoa) has a post-vegetative plant community (m)Etaphyta (m)I don't know. The development of electro-microscope technology, which revealed significant differences between bacteria, blue algae and other organisms, led to the introduction of the concepts of the original and the real. Whitaker (1969): fungi botanical animal community. With the refinement and widespread application of mirror technology and the accumulation of biological and chemical knowledge, it is widely accepted that the vision of the original nuclear organism is the basis for classification of modern biological systems. 6-category: the 5-category system does not reflect the non-cellular stage. Our well-known entomologist, chen shifu (1979), proposed three six-tier systems in the general domain, namely: the noncellular (including viral) former nuclear (including bacteria and blue algae) general nuclear (including plants, fungi and animals). 8-5 systems, basic knowledge of animal taxonomy: knowledge of animal taxonomy is a necessary basis for learning and studying animalology. Scientific research in any field, including macro, micro and related areas such as agro-forestry and fisheries, requires, first and foremost, the correct identification of the research material or the species (species) to which it is directed, otherwise any higher level of research will lose its objectivity, contrast, repetitiveness and scientific value. 10
