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

- Team discovers invasive-native crayfish hybrids...on October 8, 2021 at 7:24 am
In a study of crayfish in the Current River in southeastern Missouri, researchers discovered—almost by chance—that the virile crayfish, Faxonius virilis, was interbreeding with a native crayfish, potentially altering the native's genetics, life history and ecology. Reported in the journal Aquatic Invasions, the study highlights the difficulty of detecting some of the consequences of biological invasions, the researchers say.
