Barracudas usually swim actively in clear water searching for schools of plankton-feeding fish. Their silver coloring and elongated bodies make them difficult for prey to detect, especially when viewing them head-on. Barracudas depend heavily on their sense of sight when they hunt, noticing everything that has an unusual color, reflection, or movement. Once a barracuda sights an intended victim, its long tail and matching anal and dorsal fins enable it to move with incredibly swift bursts of speed to catch its prey before it can escape. Barracudas generally assault schools of fish, rushing at them head first and snapping their strong jaws right and left.
When barracudas are mature, they usually swim alone, however, there are circumstances when they tend to school. Two such instances are while they are young and when they are spawning. Additionally, to feed more easily, barracudas sometimes swim in groups. In this case, they can herd schools of fish into densely populated areas or chase them into shallow water; when the barracudas accomplish this, they can eat practically all the fish they want at leisure.
