Barracudas can get pretty big and they live up to 15 years since they don't have many predators other than Orca Whales and Sharks.
A Barracuda can grow to lengths of 4.9 feet and weigh up to 53 lbs.
There was a 102 lbs Barracuda caught in the African country of Gabon in 2002 by Dr. Cyril Fabre and it was almost 7 feet long.
