Answer 4

A vertebrate is an animal with a backbone (spine) and an invertebrate has no backbone, usually it has an exoskeleton.

The classification of Vertebrates is comprised of mammals, birds, reptiles, amphibians, rays and sharks, bony fish and cyclostomes (jawless fish like hagfish). All other animals, sea creatures and insects are invertebrates.

To be classified in the Subphylum of Vertebrata (vertebrate) an animal must have an internal skeleton, a head, central nervous system/brain, and a neural tube.

The taxonomic hierarchy is:

Kingdom: Animalia - animals
Subkingdom: Metazoa - animals with digestive tract
Phylum: Chordata - animals with neural tube
Subphylum: Vertebrata - animals with backbone.

Terminology:
Vertebra - one of the bones that make up the spinal column (backbone).
Vertebrae - plural for vertebra.
Vertebral - having to do with the backbone, e.g., vertebral column.
Vertebrate - animal possessing a vertebral column (a backbone).
Invertebrate - animal without a backbone.

All animals with vertebrae are vertebrates. A vertebra is one of many vertebrae, the bones that make up the backbone, which is also called a vertebral column or spine.

Examples:

Vertebrates: eagles, people, fish, whales, platypuses, toucans, horses, dogs, cheetahs, gophers, koalas, peawingspans, penguins, pythons, salmon, turtles, frogs, monkeys, hippopotamuses.

Invertebrates:
bugs, jellyfish, lobsters, worms, oysters, crabs, ladybugs, starfish, octopi, coral, stagbeetles, slugs, mosquitoes, horseflies, sponges.


Related Information:
There are a few exceptions and qualifications in more esoteric study of the subject and classifications, although the basic definition and differentiations apply in general. One example of an exception is the ancestral group known as Chordates and include lancelets, sea squirts and acorn worms. They are members of subphylums: Cephalochordata ("Head cord"), Urochordata ("Tail cord") and Hemichordata ("Half-cord"), respectively.
