all VERTEBRATES share common characteristic that consists of a backbone, or VERTEBRA, that's a part of their endoskeleton, lungs or gills for breathing, protective skin, some type of mobility, and a nervous system that processes sensory information from their environment.
more than 98% of all animalsare INVERTEBRATES, which lack backbones. invertebrates also have the highest amount of deffirent species.
since they don't have skeletons made of bone invertebrates bodies are supported with fuild- filled HYDROSTATIC, skeletons such as jellyfish, or hard outer shells like insect.
