Invertebrate anatomy

Invertebrate anatomy refers to the body structure of animals without a backbone, including groups like insects, worms, and jellyfish. These creatures have diverse forms and systems. For example, many invertebrates have soft bodies protected by an exoskeleton (like insects) or a hard shell (like mollusks). They may possess specialized organs for digestion, respiration, and reproduction, often arranged in unique ways. Unlike vertebrates, invertebrates do not have a central skeletal system, which allows for various adaptations to different environments, from the deep sea to terrestrial habitats. Overall, invertebrate anatomy showcases the remarkable versatility of life forms.
