1.	What are vertebrate and non vertebrate??
Answer» Invertebrates: are animals that neither possess nor develop 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.Vertebrates:The main characteristic of this group of animals is that they possess vertebrae; a highly specialized bone-type which joins together to compose a backbone. Its function is to protect and sustain the spinal cord and connect it to the nervous system. Another important feature is that vertebrates have different sexes.Examples are mammals, birds, fish, amphibians, and reptiles.
