Spiders eat their food through a process called external digestion. The gut, intestine and esophagus of a spider are designed to take in mostly liquids. The spider regurgitates digestive fluids onto the prey to digest it working more or less as a tenderizer. Once the prey begins to liquefy, it is chewed with the jaws (chelicerae) and the fluid is sucked back into the mouth together with some liquefied "'meat" from the prey.
The spider repeats this process as often as necessary to digest and ingest all but the inedible hard parts.

Sound is directed down the ear canal to the ear drum, and then via the tiny middle ear bones (the smallest bones in the body) to the inner ear, which houses the sensory organ of hearing. This organ rests on a membrane that vibrates selectively to different sound frequencies, and so acts as a sound filter, which sorts sound frequencies into groups. High frequencies produce maximal vibrations at the beginning of the coiled inner ear, and low frequencies do the same at the other end.
