Movement and Locomotion By Mrs Sandy Gomez
Is the act of self-propulsion • Is the hallmark of animals • Indispensable for animal survival What is locomotion?
Energy • Overcome 2 forces: • Friction • Gravity • Energy consumption varies according to the medium Requirements for Locomotion
Swimming • Walking • Flying • Crawling • Running • Hopping Forms of Locomotion
Most animals are reasonably buoyant, gravity is no problem • Water is denser than air, friction is a major problem • Animals develop adaptations Locomotion in Water
Torpedo-like shape Adaptations for Locomotion in Water
Using legs as oars Adaptations for Locomotion in Water
Moving body from side to side or up and down Adaptations for Locomotion in Water
Bodies must support itself • Strong skeletons • Powerful muscles • Resist gravity • Low friction (air resistance) • Maintain balance • Walk, run, hop. Crawl, etc. Locomotion in Land
Animals that hop Adaptations for Locomotion on Land
Animals that walk or run Adaptations for Locomotion on Land
Animals that crawl Adaptations for Locomotion on Land
Animals that fly Adaptations for Locomotion on Land
What is locomotion? • Why is locomotion indispensable for animal survival? • How does the strength of friction and gravity vary in the mediums that animals live in? • How does energy consumption vary in the mediums in which animals move? • List 2 examples of animals that use each type of locomotion? • How do animals keep their balance when moving? • What are adaptations present in animals that swim? • What are some adaptations present in animals that move on land? • What are some adaptations present in animals that fly?
