Have you ever noticed an organism moving? Do they move like you do or like any human does?

No, right! They move differently and uniquely.

The body of organisms is very different from humans. Some organisms have different type of muscles or bones for movement. This makes the way they move from one place to another, very different and unique in many aspects. Let’s take a look at some of the types of movements that we see in organisms.
• Movement of Earthworm

The earthworm is a long thread-like insect found on the earth. It eats small insects and wastes in the soil and throws its wastes in the soil. This process makes the soil very fertile. It has circular ring-like structures present all over its body. These structures act like muscles for the earthworm and can contract and expand according to its need.
So, when an earthworm wants to move, the front of its body expands forwards, whereas the back of the body remains fixed at the same place. Later, the front part of the worm sticks to the surface and the back contracts after detaching from the surface and comes forward. Repeating this expansion and contraction, the earthworm moves forward.
• Movement of Snail

Now Snails have very soft and slimy body, because of which, they have a heavy shell on their backs for protection. The soft and slimy body of snail moves very slowly. If you look carefully, the bottom of their bodies makes a wave-like motion to move from one place to another. This wave like motion lifts the snail a little from the ground and pushes it further. Still, the speed of their movement is very slow.
• Movement of Cockroach

Cockroaches have small plate-like structures on their surface that permits movement. They have three pair of legs on their body that help them to walk and climb on surfaces. They have a pair of wings too, that helps them to fly from one place to another. The muscles on the body of cockroaches have different functions for movement. The muscles attached to the legs help to walk, whereas those attached to wings help to fly.
• Movements of Birds

Birds have many movements. Their wings help them to fly, whereas their feet help them to walk on the ground. Some birds have special feet that even help them to swim in the water. The legs of the birds are designed in such a shape that they can sit on a tree branch and can hold their feet in them too.
Bones of birds are very light as compared to other animals having bones. This helps them in their flight. The bones attached to their shoulder are strong and modified to be as wings. the wings move up and down, which results in the flight of birds.
• Movements in Fishes

The bodies of fishes are called streamlined bodies. This means that their heads are smaller than the middle part of their bodies and both the ends of their bodies are thinner than the middle part. This shape allows fish to cut through the water easily and makes it easy to swim in the water.
The front of fish and its tail make a rhythmic wiggle that pushes it to move forwards in water. The fins of the fishes help them to maintain balance in water and helps them to decide the direction of swim.
• Movement in Snakes

Snakes have scales all over their body. They have very long and flexible backbone that stretches throughout their body. This backbone gives them the strength for movement. The muscles of the snake are thin and interconnected to the backbone. For movement, the snakes bend their bodies in loop-like fashion, which pushes them forward. The movement is, however, not in a straight line.
So, we learned about some of the movements made by different organisms. Isn’t it interesting how all these animals move in their own unique and different way?
