===Lateral Lines===

Although the cuttlefish can't hear, it can detect sound in the form of pressure waves using its lateral epidermal lines. Seen here via a scanning electron microscope, these lines consist of thousands of hair cells. The cells seem to be especially sensitive to sounds ranging between 75 and 100 Hz, with 100 Hz being similar in frequency to a typical automobile engine running at maximum speed. One physiological study showed that in total darkness, healthy cuttlefish could capture about 50 percent of available prey, whereas cuttlefish with compromised epidermal lines could capture only about 30 percent. The hair cells can also be used in defense, allowing cuttlefish to detect the movement of possible predators.
