Animals are multi-celled consumers that take food into their body, where they digest it and absorb the released nutrients. An animal develops from an embryo (an early developmental stage) to an adult. Animal life began in the sea, and the Earth's oceans still hold the greatest store of animal diversity. The majority of animals are invertebrates, meaning they do not have a backbone. Identify each invertebrate by matching it with its characteristics.
