Invertebrate : lacking a spinal column
also : of, relating to, or concerned with invertebrate animals — Webster
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

Researchers at Eötvös Loránd University (ELTE) have created a new disease model that has contributed to a better understanding of Bloom syndrome and the sex determination processes of zebrafish. The study, linking two seemingly unrelated topics, was carried out by the research teams of Mihály Kovács (Department of Biochemistry) and Máté Varga (Department of Genetics) and published in the scientific journal Cell Death and Disease. In addition to providing important information on the […]

Fossils can tell scientists a lot about an animal such as their morphology, their environment, and where to place them in the tree of life. One thing though that's very difficult to observe in the fossil record is an animal's reproductive behavior. It takes a very uniquely preserved fossil to reveal the secrets behind reproductive strategies in some of the earliest complex animals.
