Sorry guys...I'm not referring to "them". What I am referring to is the big fish shown below that has more than its fair share of teeth. Get a gander at the choppers on this thing.
It is a Giant Tigerfish (aka Goliath Tigerfish, African Tigerfish). Tigerfish and piranha belong to the same family (Characidae) but are entirely different species, according to someone well versed in such things. I believe that it was caught in the Amazon.
