Question

Collect the pictures, newspaper cuttings, etc., which show the skeletal systems of various animals, and observe the differences between them.

Answer 1

I collected pictures and newspaper cuttings showing the skeletal systems of different animals and observed them carefully. I found that the skeletons of animals are different in shape and size according to their body structure and way of life.

• Fish: Its skeleton is light and flexible, with a backbone, ribs, and many small bones that help it swim.
• Bird: Its bones are light and often hollow, which helps the bird fly. The skeleton has strong wings and a lightweight body.
• Snake: It has a long backbone and many ribs. Its flexible skeleton helps it move by bending its body.
• Frog: It has a short backbone and strong hind limbs that help it jump.
• Dog/Cat: They have strong bones and four limbs that help them walk, run, and jump.
• Cow/Horse: They have strong leg bones and a sturdy skeleton to support their large body weight.
• Elephant: It has very thick and strong bones, especially in its legs, to support its heavy body.
