  "term": "Animal Skeleton",
  "field": "Environment",
  "definition": "A supportive or protective structure or framework of an animal, a plant, or part of an animal or plant. In animals it is an external (exoskeleton) or internal (endoskeleton) support structure, against which the force of muscles acts. Vertebrates have a skeleton of bone or cartilage; arthropods have one made of chitin; corals have one of calcium carbonate: sponges have a mass of spicules; many other invertebrates use a hydrostatic skeleton, which is an incompressible fluid-filled region of their body. In plants, the skeleton may be a rigid protective covering, as in the shell of a diatom, or the vascular system of a vascular plant; in scleractinian corals, the structurally supporting matrix of aragonite crystals formed on the outside of the polyp, technically an exoskeleton, or the structural support for an octocoral.",
