Webbed feet are used for moving faster through water by aquatic animals, and aquatic animals moving through water are also subject to the principles of aerodynamics. Given these facts, aquatic animals in water use webbed feet due to what among the following options:
- ability to sense light
 - principals of aerodynamics
 - kinetic energy
 - swimming slower
 - refraction of light
 - poor swiming
 - bending light rays
 - dynamic relationships
