More than a million species of living organisms have been discovered and described so far and a large number of them are yet to be discovered. Scientists involved in this task, called taxonomists, estimate that there may be around 30 million species of living ..

Summary - Biologists estimate that there are about 30 million species of living organisms inhabiting this biosphere and only a million and half of it have been discovered and described so far. The species of plants and animals identified so far exhibit a great deal of variation ..

Among the members of the animal kingdom, about 95% do not posses a backbone (or vertebral column) and hence are described as invertebrates. The remaining animals represent a group called chordates, which posses a solid supporting structure on the dorsal side of the body called notochord, at some st..
