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.
