Introduction

All animals move in search of food or to protect themselves and their babies from  being hunted, or to find and build resting and breeding places. Animals show different  types of movements. The limbs of animals are modified according to the way they  move.

Land animals

  • Most animals living on land have four limbs
  • The two limbs in front are called  forelimbs and the two behind are called hind limbs
  • Some animals use all four limbs to move. For example, Horses, Cows, Tigers, Zebra etc.

  • Some use only their hind limbs to move. For example, Kangaroos, Crocodiles, Lizards and turtles have four shorts legs which help them crawl.

  • Human beings use their hind limbs to walk and forelimbs to hold, pick or carry things and to perform many other activities.

  • Some animals like snakes and earthworms have no legs. Snakes move by curving and straightening their body while the earthworms move by shortening and elongating  their body.

Water Animals

All water animals swim by paddling and pushing back water. Different animals use different organs for swimming:

  • Fishes swim by moving their body and tail from side to side. A pair of fins helps them in balancing, changing direction and stopping. Some fishes use their fins like oars to push the water and move forward.

Birds

  • The forelimbs of birds are modified into wings, which help them fly in air. 
  • Wings have feathers and they are attached to the chest bone of birds.
  • Birds have streamlined bodies enclosing light and hollow bones. 
  • These bones make their bodies lighter and easy to soar in the air. 
  • Some birds like ostrich, emu and kiwi have poorly developed wings, hence, they cannot fly.

Insects

  • All insects have six legs, which they use to move. 
  • Some insects like the butterfly, honey bee and house fly have wings to fly. 
  • Water insects like the water boatman use their legs as oars to paddle and swim.

Migration

Many animals migrate in search of favorable conditions. They travel thousands of kilometers to escape the cold weather, find food and also find a suitable place to give birth to their young ones. When conditions are again favorable, they go back to their original habitats. The large-scale movement of animals in search of favorable conditions is called migration.


Reproduction in Animals

Movement in Animals | Science Class 5

The process by which animals produce progeny like them is known as reproduction. Some smaller animals reproduce by fissionSome organisms reproduce by growing buds on their body while many animals reproduce directly by giving birth to their young ones or by laying eggs. For example, a cow gives birth to a calf; a hen lays eggs from which chicks hatch out

FAQs on Movement in Animals - Science Class 5

1. What are some examples of land animals?
Ans. Some examples of land animals include lions, elephants, giraffes, wolves, and rabbits. Land animals are those that primarily live and move on land.
2. What are some examples of water animals?
Ans. Some examples of water animals include fish, dolphins, whales, sharks, and turtles. Water animals are those that live and move primarily in water.
3. How do birds move?
Ans. Birds have the ability to fly, which is their primary mode of movement. They have wings that allow them to soar through the air and travel long distances. In addition to flying, birds can also walk, hop, and swim.
4. How do insects move?
Ans. Insects have different ways of moving depending on their species. Some insects, like ants and beetles, walk or crawl on land. Others, like dragonflies and butterflies, have the ability to fly. Some insects, such as water striders, can even glide on the surface of water.
5. Why do animals migrate?
Ans. Animals migrate for various reasons, including finding better food sources, escaping harsh weather conditions, or reproducing. Migration allows animals to travel to different habitats where they can survive and thrive. Some examples of migratory animals include birds that fly long distances to breed or find warmer climates, and wildebeests that travel in search of fresh grazing grounds.
