What is an interebrate?

An invertebrate is an animal that lacks a backbone or spinal column. This diverse group includes organisms such as insects, arachnids, mollusks, and cnidarians. Invertebrates make up about 95% of all animal species on Earth, playing crucial roles in ecosystems as pollinators, decomposers, and as part of the food web. Their adaptability and varied forms allow them to inhabit numerous environments, from deep oceans to terrestrial habitats.
