∙ 10y agoAny animal that has a ertebral vcolumn or "backbone" is called Vertebrate .It is not valid taxonomic category .
Basic characteristics: a spinal column made up of vertebrae. In adult vertebrates, the spinal column surrounds or replaces the notochord
Other characeristics:
- The anterior part of the dorsal, hollow nerve cord is enlarged into a brain
- The body usually is divided into a head, neck and tunk. the head contains the brain and various sense organs
- In most vertebrates, a tail is present at some stage of development
- There is a jointed, internal skeleton
- There are two pairs of appendages (like legs, or fins)
- There is a heart with two to four chambers. The circulatory system is closed, and the red blood cells contain hemoglobin
- In aquatic vertebrates, gas exchange takes place in the gills.In land vertebrates, it occurs in the lungs. (breathing.)
- A cranium is present hence this group is also called Craniata .
- the body covering, the skin, is made of at least two layers. the skin often forms other structures, such as glands, scales, feathers, hair, nails, claws, horns and hoofs.

Mammals:
- covering of fur or hair
- breathe using lungs
- warm-blooded
- young are born alive (except for monotremes)
- young suckle on mothers' milk
Birds:
- covering of feathers
- breathe using lungs
- warm-blooded
- young are hatched from eggs
Reptiles:
- covering of scaly skin
- breathe using lungs
- cold-blooded
- young may be hatched from eggs or born live
Amphibians:
- covering of moist skin
- breathe using lungs as adults but gills as juveniles
- cold-blooded
- young are usually hatched from eggs, with some exceptions being born alive
Fish:
- covering of scales
- breathe using gills
- cold-blooded
