Difference Between Locomotion and Movement

Locomotion and movement are two important terms in the study of motion. The movement of an organism from one place to another is known as locomotion. A few examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized. Movement can be both voluntary and involuntary. For example, walking is a voluntary movement, while breathing is an involuntary movement.

Difference Between Locomotion and Movement

While both locomotion and movement sound similar in their meaning, there are a few interesting differences between the two. Let us explore these concepts better by understanding the difference between locomotion and movement:

Locomotion Movement
Moving away from the original position of an organism is locomotion. Movement can happen with or without moving away from an organism’s original position.
It is always voluntary. It can either be voluntary or involuntary.
Locomotion takes place at the organism level. A movement takes place at the biological level.
Locomotion doesn’t necessarily require energy when a free-floating organism is considered. Movement requires energy.

Plants don’t possess the ability to move from one place to another but various types of movement take place within plants, including phototropism, hydrotropism, geotropism, thigmotropism, etc. It is important to know the differences between the two as we often tend to use these terms interchangeably, thinking both mean the same.

Animals exhibit the most fascinating forms of movement and locomotion and this is evident from the plethora of behavioural and evolutionary traits exhibited. For instance, one of the very first groups of organisms to take flight is the insects, which made the leap into the air roughly  412 million years ago. The very first vertebrates to take flight was the Pterosaurs, which evolved 320 million years ago.

The ocean was a far more interesting place as organisms exhibited even more advanced forms of movement. Sharks and other fish used their tails and flippers to propel themselves through the ocean, but one group of animals which includes squids and jellyfish use jet propulsion to move through the water.
