The Science of Jumping. Different Frogs, Different Styles
Frogs. The beloved creature that almost every child has seen or played with. Frogs are part of a large and diverse group of organisms called amphibians that are mainly carnivorous. Frogs can inhabit a variety of environments from high in the trees to swimming underwater or hiding underground. They can be found on every continent except Antarctica. They have several special characteristics unique to them. Frogs have powerful hind legs that allow them to jump distances, the ability to absorb water through skin so that they do not have to drink, and can breathe through their skin.
The style of jumping that a frog has is influenced by the environment that it lives in. Different species of frog have different jumping abilities. Frogs that live in trees can jump high but do not cover much distance. While frogs that lived in water could jump long distances but not very high from the ground. Frogs that lived in burrows had jumps that were low in both distance and height. Ultimately this can all be attributed to the shape of the individual frog. Aquatic frogs have long limbs and bodies meant for swimming. Burrowing frogs have short limbs and thickset bodies to help with digging.
The ability to jump distances whether short or long has helped frogs. They can use this ability to escape from predators. This can also make travelling a bit faster as opposed to walking. Frogs can leap 20 times their body length. For some comparison fleas can jump 100 times their body length. So, the next you are playing hopscotch think about how you could be hopping if you could jump many times your body length.
