Animals are divided into two main groups, Invertebrates and Vertebrates. Vertebrates, such as man, have a spine and an endoskeleton, ( internal skeleton) to which all their muscles are attached. They also have a rib-cage which protects the heart and lungs etc, as well as a cranium, (skull) which protects the brain. Some INVERTEBRATES have no skeletons, such as earthworms and jelly-fish, but others, the ARTHROPODS, have an EXOSKELETON, ( outer skeleton) made up of chitin and calcium carbonate. The arthropods can be divided into ; the insects; the Spiders, the crustaceans, (lobsters, etc) and the Diplopods/myriapods, ( centipedes etc). The muscles and body organs are all INSIDE the exoskeleton.

∙ 7y agoAt a cellular level, the cell membrane provides a certain level of defense by only allowing in certain materials and keeping out others. For plants, their cell wall also helps with this. For multicellular organisms, structures like the immune system's white blood cells can seek and destroy invaders such as viruses and bacteria. Larger threats, such as predators or aggressive members of the same species, can be fended off with teeth, claws, quills, barbs, stingers, saliva, or even invented weapons (in a few species, most notably us!).
