Feeding in Uranoscopus scaber is characterised by bending of the body just behind the head. Bending is related to the organisation of the first five vertebrae: vertebral centra of lesser height fitting one into the next; short, less tilted neural spines, presence of many intervertebral ligaments. Bending of the vertebral column causes the head to rotate upward and the mouth to open just beneath the prey; it also brings the pharyngeal jaws, shifted with respect to each other at rest, to face each other.
