Movement in animals

 


MOVEMENT IN ANIMALS


•    Without the ability to move, there would be no life on Earth.

•    For living, animals have occupied almost all the places that are suitable for life by moving around. Like;

     1. The underground soil

     2. The surface of the ground

     3. Water and air

•    Animals need to move in search of food, water, and shelter, and also to escape from predators (Animals that kill and eat other animals).

•    The varied nature of moving is indicated even by different sorts of movement like: crawling, digging, walking, running, climbing, jumping, flying, sneaking, floating, gliding, trotting, galloping, and so on.

•    By movement we usually mean displacement from one place to another. But an animal can also simply move its body or limbs – that is, change their position.

•    A large number of animals move around using their limbs and the limbs are moved by muscles.

•    Animals move in different ways. Some walk, some fly some swim through water, some crawl, some hop, etc.

•    There are many other ways in which animals show movement.

•    The way an animal moves is linked with its body structure.

•    The body structure of an animal that determines the way it moves which is called the backbone.

•    Based on the presence or absence of backbone, animals can be divided into two groups–  

     1. Vertebrates

     2. Invertebrates

 

Vertebrates:

•    Animals that have a backbone are called vertebrates.

     For example- human beings, birds, fish, snakes, etc

 

Invertebrates:

•    Animals that do not have a backbone are called invertebrates.

     For example- insects, spider, jellyfish, etc.
