nvertebrates are an extraordinarily diverse group of animals that include over 30 phyla. Invertebrates do not have a backbone, nor a bony skeleton. This large group of animals includes sponges, cnidarians, flatworms, roundworms, segmented worms, mollusks, echinoderms, and arthropods.\nSubtopics\nArthropods (290) Flatworms (6) Cnidarians (6) Mollusks (9) Echinoderms (7) Segmented Worms (5)

Rotifers   are the only I can think of  now if it were Phylum Mollusca it could be Snails, Clams, and squids\n                                 good luck

Of the million or more animal species in the world, more than 98% are invertebrates. Invertebrates don't have an internal skeleton made of bone. Many invertebrates have a fluid-filled, hydrostatic skeleton, like the jelly fish or worm. Others have a hard outer shell, like insects and crustaceans. There are many types of invertebrates. The most common invertebrates include the protozoa, annelids, echinoderms, mollusks and arthropods. Arthropods include insects, crustaceans and arachnids.

Linnaeus used structural similarities. Unfortunately, this led to many, we know now, illogical classifications. For instance, anemones (animals) and mushrooms (fungi) were classified as plants.\n\nBut, he did come up with a very workable/useable system.

Any biological species or group of species whose function, population, or status can be used to determine ecosystem level or environmental integrity. An example of such a group of organisms is copepods and other small water crustaceans present in many water bodies.\n\nCopepods are a group of small crustaceans found in the sea and nearly every freshwater habitat. Many species are planktonic, but more are benthic, and some continental species may live in limno-terrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds and puddles, damp moss, or water-filled recesses (phytothelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Some copepods are parasitic and attach themselves to fish, sharks, marine mammals, and many kinds of invertebrates such as molluscs, tunicates, or corals.\n\nCopepods form a subclass belonging to the subphylum Crustacea (crustaceans). Some authors consider the copepods to be a full class. The group contains ten orders with some 14,000 described species. A scientist that studies copepods is a copepodologist.\n\nCopepods are very important food organisms for small fish, whales, and other crustaceans such as krill in the ocean and in fresh water. They are typically 1-2 mm long. They feed directly on phytoplankton, catching cells singly. Some scientists say they form the largest animal biomass on earth. They compete for this title with Antarctic krill (Euphausia superba).\n\nCopepods are sometimes found in the public mains water supply, especially systems where the water is not filtered, such as New York City and Boston, Massachusetts. This is not usually a problem in treated water supplies. In some tropical countries, such as Peru and Bangladesh, a correlation has been found between copepods and cholera in untreated water, because the cholera bacteria attach to the surfaces of planktonic animals. The risk of cholera from infected water can be reduced by filtering out the copepods (and other matter), for example with a cloth filter.\n\nMany species have neurons surrounded by myelin, which is very rare among invertebrates (other examples are some annelids and malacostracan crustaceans like palaemonid shrimp and penaeids). Even rarer is the fact that the myelin is highly organized, resembling the well-organized wrapping found in vertebrates (Gnathostomata).\n\nSome copepods are very evasive and can jump with extreme speed over a few millimeters (warning: takes some time to load to the correct speed):\n\n \nSlow-motion macrophotography video (50%) of juvenile Atlantic herring (38 mm) feeding on copepods - the fish approach from below and catch each copepod individually. In the middle of the image a copepod escapes successfully to the left.This scene was scanned with the ecoSCOPE, an underwater high speed microscope. Because clupeids (herrings) and copepods are both significant in terms of global biomass, this is the first record of what is one of the largest carbon flows of any animal food-chain transition in the oceans. It is a predator / prey relationship running at extreme speeds, with chances for both sides. Very little is known about the details, in spite of its importance for global processes, because copepods are difficult to keep in the laboratory and lose most of their escape capacity, and herring are very fast, alert and evasive organisms and flee normal camera systems or SCUBA divers. Oceanographers point out the importance of learning more about the influences of physical parameters, such as light, pollution or temperature, or the effects of hunting in a swarm. This copepod-herring relationship has implications for the fate of carbon in marine systems. If the copepod 'wins' (escapes), much carbon will sink with its fecal pellets into the depth of the oceans (see biological pump), sequestering carbon dioxide in the benthos. If the herring

"Bug" is not necessarily a scientific term.  People commonly refer to insects as "bugs".  Butterflies are insects.\n\nMicrobiologist also refer to bacteria and other single celled organisms as "bugs".\n\nSome people also call spiders "bugs" although they are arachnids and not insects.\n\nAnd when you get a virus like a cold, people will ask "Did you catch the bug that is going around?"

Interesting question, because it shows the difference between two levels or types of speech.\n"Bug" is a common term that people use with different meanings.\nIn contrast, scientific names of natural groups have the same definition and content all around the world. In that sense, 'Insecta' (insects) is a class of arthropods that includes animals with articulated exoskeleton, 3 pairs of legs, 1 pair of antennae, and body divided into head, thorax and abdomen (among other characteristics). The definition of insect is the same everywhere.\nSo, those terms are not opposites, but whether one comprises the other will depend on the popular definition of 'bug'. Some people include also spiders, which are not insects, in the 'bug' category. For others, bugs are only beetles, and therefore would be included in the definition of Insects.\nI looked in my dictionary and it said:\n1. A true bug. \n2. An insect or similar organism, such as a centipede or an earwig. \n3. A disease-producing microorganism.\n\nSo I'd say that for most people, bugs are "insects + others" as you put it.

It is broadly divided into zoology, the study of animal life, and botany, the study of plant life. Subdivisions of each of these sciences include cytology (the study of cells), histology (the study of tissues), anatomy or morphology, physiology, and embryology (the study of the embryonic development of an individual animal or plant). Also included in biological studies are the sciences of genetics, evolution, paleontology, and taxonomy or systematics, the study of classification. The methods and attitudes of other sciences are brought to the study of biology in such fields as biochemistry (physiological chemistry), biophysics (the physics of life processes), bioclimatology and biogeography (ecology), bioengineering (the design of artificial organs), biometry or biostatistics, bioenergetics, and biomathematics. Evidences of early human observations of nature are seen in prehistoric cave art. Biological concepts began to develop among the early Greeks. The biological works of Aristotle include his observations and classification of his large collections of animals. The invention of the microscope in the 16th cent. gave a great stimulus to biology, broadening and deepening its scope and creating the sciences of microbiology, the study of microscopic forms of life, and microscopy, the microscopic study of living cells. Among the many who contributed to the science are Claude Bernard, Cuvier, Darwin, T. H. Huxley, Lamarck, Linnaeus, Mendel, and Pasteur. See marine biology.\n\nSee T. Lenoir, The Strategy of Life (1989); C. A. Villee et al., Biology (3d ed. 1989); N. A. Campbell, Biology (3d ed. 1993).

Entomology is the scientific study of insects. Insects have many kinds of interactions with humans and other forms of life on earth, so it is an important specialty within biology; unlike many other fields however, entomologists include both persons studying insects for their own sake, and those employed by commercial concerns interested in the control of insects.

Taxonomic categories? I can name some of the taxa we're included in, but the categories change rather frequently. \n\nAnimalia\nEumetazoa\nBilateria\nDeuterostomia\nChordata\nCraniata\nVertebrata\nGnathostomata\nEuteleostomi\nSarcopterygii\nTetrapoda\nAmniota\nSynapsida\nMammalia\nTheria\nEutheria\nArchonta\nPrimates\nHaplorhini\nAnthropoidea\nHominoidea\nHominidae\nHomo \nH. sapiens\n\n\nAll these nested taxa are "stages of evolution" if by that you understand evolutionary acquisitions.
