Invertebrate : lacking a spinal column — Merriam-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

    Resource managers and policymakers need robust data about marine ecosystems for decision-making and setting sound policies. However, data about marine life can be challenging to collect, integrate, and analyze. Invertebrate animals are a key component of life on the seafloor, but their wide range of body sizes and diversity make it especially difficult to understand their abundance and distribution.

    A team of ecological modelers from the UK Center for Ecology and Hydrology has found that despite efforts by officials and farmers in the U.K. to protect them, populations and diversity of invertebrates is still dropping around croplands. In their study, reported in the journal Proceedings of the Royal Society B, the group analyzed citizen science data on more than 1,500 invertebrate species in the U.K.

    Snails may look slow and sleepy, but evolutionarily the freshwater mollusks in Lake Biwa have been busy. However, despite evidence of morphological and genetic variation, new species divergence long went unnoticed.
