Invertebrate : lacking a spinal column — Webster   See also   OneLook


Roget’s II (, Merriam-Webster Thesaurus, Visuwords


Invertebrate is an animal that neither possess nor develops a vertebral column (commonly known as a backbone or spine), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include insects; crabs, lobsters and their kin; snails, clams, octopuses and their kin; starfish, sea-urchins and their kin; jellyfish, and worms. The majority of animal species are invertebrates. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. — Wikipedia

Invertebrate Zoology is the subdiscipline of Zoology that consists of the study of invertebrates, animals without a backbone (a structure which is found only in fish, amphibians, reptiles, birds and mammals). Invertebrates are a vast and very diverse group of animals that includes sponges, echinoderms, tunicates, numerous different phyla of worms, molluscs, arthropods and many additional phyla. Single-celled organisms or protists are usually not included within the same group as invertebrates. — Wikipedia

    For more than 100 years, biologists have wondered why animals display different types of life cycles. Some species, like humans and most vertebrates, develop directly into a fully formed yet smaller version of an adult. In contrast, many other animals give rise to beautifully diverse intermediate forms we call larvae, which then metamorphose into the adult.
