>For other uses, see Beetle (disambiguation). Adephaga Archostemata Myxophaga Polyphaga See subgroups of the order Coleoptera Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species in it than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species — described and undescribed — at between 5 and 8 million. This is why, when J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about God, he replied, "An inordinate fondness for beetles". See more at Wikipedia.org...

>For other uses, see Skeleton (disambiguation). In biology, the skeleton or skeletal system is the biological system providing support in living organisms. (By extension, non-biological outline structures such as gantries or buildings may also acquire skeletons.)Skeletal systems are commonly divided into three types - external (an exoskeleton), internal (an endoskeleton), and fluid based (a hydrostatic skeleton), though hydrostatic skeletal systems may be classified separately from the other two since they lack hardened support structures. Large external skeletal systems support proportionally less weight than endoskeletons of the same size, and thus many larger animals, such as the vertebrates, have internal skeletal systems. Examples of exoskeletons are found in arthropods, shellfish, and some insects: the skeleton forms a hard shell-like covering protecting the internal organs. See more at Wikipedia.org...
