Fun Facts

  • Different animal coverings include skin, feathers, fur, scales, or exoskeletons.
  • A crab's exoskeleton protects it from being eaten.
  • Crabs shed their entire exoskeleton when they grow.

Why Do We Need To Know About Exoskeleton

Studying exoskeletons helps us learn about how living things protect and support themselves. This is important for people who work in areas like engineering and healthcare. For example, the tough outer shell of a crab is like natural armor. It has inspired people to create protective clothing and gear. This shows us how nature’s designs can help us make better technology.

Also, looking at exoskeletons and similar things like bird feathers and snake scales can teach us a lot about moving smoothly and efficiently. This is useful for designing airplanes and robots. These natural examples help us come up with new ideas in technology. It’s helpful to understand exoskeletons for real-life projects.
