Animal Diversity

                                   Vertebrates and invertebrates Animal world consists of millions of different animals with a wide diversity. We may have grouped animals based on different criteria. Mode of locomotion, body shape, body colour, size of the body and mode of nutrition are some of the criteria you can use to group animals. Therefore you will learn that there is a vast diversification in animals. Human is also a member of this diversified animal world.   Animals are grouped for ease of identification and study, considering criteria such as mode of locomotion. For example bats, butterflies, crows are grouped as 'flying' animals. However, sciencetific classification becomes essential due to the vast diversity in other features. Many animals, including humans, have a backbone observed as the central line of bones. Also some animals do not possess a backbone.    ...

          Adaptation of organisms to environment Living things are found in different places- water, land, air on other living things and even inside them. Some organisms thrive in challenging places like snow, deep sea, deserts, hot springs because they can adapt to these environments.  The ability of organisms adapt to their environment is called adaptation .  These adaptations are useful for them to fulfil their needs,               Ex:   food, shelter, protection Here you can find more information about animal adaptation ;    Usefulness of colour for the existence of animals Colour serves various essential purposes for the existence of animals, contributing to their survival, communication and overall adaptation to their environments.  The difficulty to identify animals separately from their surroundings due to blending of body colour to particular environments is called Camouflage ...
