Class 11 Biology Chapter 4 Animal Kingdom: Important Topics

The Animal Kingdom is a diverse group of organisms that share certain characteristics. Kingdom Animalia consists of organisms that range from the simplest of animal forms to the most complex. Some members of this kingdom seem like they would fit in elsewhere, like sponges or coral. The Animal Kingdom is the largest of all kingdoms with more than one million species.

  • Classification of Animal Kingdom

Taxonomy is the science of classifying organisms. Every species that discovered so far can be classified into five kingdoms – one among them is Kingdom Animalia or Animal kingdom.
