2. IMPORTANCE OF ANIMAL CLASSIFICATION
So far, over 10 lakhs of animal species have been identified and described.
They show a lot of diversity in structure, habits, habitats and life styles. Hence, it is very essential that every organism be given a name and classified in a systematic way. A systematic classification of organisms will help for a better understanding of the diversity of organisms and their relations.

LINNAEUS
