Another component that enhances prey detection is motion parallax [30], [31], which provides depth cues though changes in the relative position of objects at different distances caused by the movement of the observer [32].
Its low-density flesh and large oily liver make it neutrally buoyant, allowing it to drift towards its prey with minimal motions so as to avoid detection.
The extent to which unpredictable motion and prey density during the target assessment phase contribute to the classical confusion effects therefore deserves further scrutiny.
This motion attracts prey, which mistake it for a worm or an insect on a branch.
High-speed videos of lizards noshing in his lab revealed that they use their tongues to grab and swallow their prey in one fluid motion.
Bats, for example, bounce ultrasonic sound waves off insects to pinpoint their prey's location, direction of motion, and speed.
These movements require that the insect successfully make predictions about the motion of its prey as well as its own body.
They lunge forward, and with a sweeping motion grab their prey, impaling it on their double rows of sharp teeth.
These perching head movement patterns may increase the detection of prey by providing depth cues through motion parallax [50].
