What is an invertebray?

Answer 1

An invertebrate is an animal that lacks a backbone or spinal column. This diverse group includes organisms such as insects, mollusks, arachnids, and crustaceans, making up about 95% of all animal species. Invertebrates can be found in various habitats, ranging from oceans to forests, and play crucial roles in ecosystems as pollinators, decomposers, and as part of the food chain. Their lack of a vertebral column allows for a wide range of body forms and adaptations.
