Movement of Earthworm, Snail and Cockroaches | Class 6th Biology |

Every animal has its own way to move from one place to another using their limbs. Some fly, crawl or swim. In this lesson, we will learn the characteristics and locomotion (movements) of earthworm, snail, and cockroaches.
Earthworms don’t have bones. Their body is made up of many rings which are joined end to end. Earthworms have bristles which help them move or control their body. Bristles are short hair on the earthworm’s skin.
Snails are a very slow moving animal. They have a shell on the outside which protects them from climatic conditions and enemies. While moving, snails produced slimy substances called as mucous. It reduces the friction between the snail and the ground resulting in smoother movement.
Cockroaches have three legs and all move at the same time. Male cockroaches might have wings but females don’t have wings. Thing wings are used to fly a shorter distance.
