"The Barracuda is a predator by nature and reaches a size of almost two meters in length and thirty centimeters in width. The Barracuda likes to stay motionless under the cover of weeds on the seabed and attacks its prey when it comes within striking distance from the weeds where it is hiding. The ambush is very sudden, very fast, very vicious and very powerful and is over in the blink of an eye.
The symbolism of the Barracuda teaches you that you have a tendency of challenging your inner emotions and you possess a fierce urge to hit out at people which may ultimately cause more harm than good to your mental, spiritual and emotional growth. The symbolism cautions you to keep a check on your emotional outbursts so that you can lead a more controlled and better way of life."
