Animal Locomotion

Based on Bill Nye the Science Guy · Season 3, Episode 20 · 23 min

Why do animals walk, run, swim, and fly? To survive! Whether you are hunting for food, looking for a new home, or running away from a predator, you have to know how to move. But not every animal uses legs and feet!

Put Your Instincts to the Test

Think about the incredible biology of movement. Pick an answer for each question, then see if your instincts were right.

1. How do the muscles inside your arms and legs actually move your bones?
2. Spiders are incredibly fast, but they do not have standard muscles in their legs. How do they move?
3. How can a water skimmer bug stand perfectly still on top of a pond without sinking?

Understanding the Science

No matter if an animal uses fins, wings, or feet, all animal locomotion involves pushing or pulling against something. Tap the cards below to reveal the keywords of biomechanics.

Interactive: The Biomechanics Lab

Step into the lab and test your knowledge of animal engineering! You are presented with a test subject. To make it successfully cross the testing chamber, you must select the correct biological mechanism from the control panel. Match the physics to the animal to succeed!

Biomechanics Terminology
Locomotion
Muscle Contraction
Gastropod
Biomechanics
The biological ability to move from one place to another to survive.
The action of a muscle pulling (getting shorter) to move a bone.
A scientific name literally translating to "stomach foot", describing slugs.
The scientific study of how animals physically move and engineer their bodies.

Real-World Challenge

Robotics engineers at advanced technology companies spend years studying animal locomotion. If you had to design a rescue robot to safely climb over jagged, slippery rocks inside a dark cave, which animal's method of locomotion (a galloping horse, a slithering snake, or a sea star with tube feet) would you copy, and why?

Reflection

Think about how your own body moves during your favourite sport or physical activity. Which specific muscles are contracting (pulling) to power your legs or arms? Try moving incredibly slowly and feel exactly where the tension is!
