When you boat one of them fish... you use a net, don'tcha? Damn sure don't "lip" 'em... lessin' your name is Capt. Hook.
Just Googled up some pics of 'em... they look like bluegill sportin' a set of choppers that would do justice to a Great White.
And those choppers are so sharp and so interlocking that one man who was bitten by one said that he barely felt it before he realized that his finger was severely bitten and was bleeding badly. Larger ones can easily remove a finger in one bite.
Some think they're really small, but some individuals grow to over a foot long and are pretty wide.
If you have the chance, watch Jeremy Wade handle them...with great care. I think he uses pliers to remove hooks. His show, "River Monsters", recurs on Animal Planet, but you can find photos of him on the Net. He is not only an international angler, but is a biologist.
The worst bite that I ever got was from a walleye, and it hurt. I'm not going to put my hand close to the mouth of a pike, barracuda, or anything else with teeth that can really do some damage. BTW, walleye are a form of perch, not "walleyed pike" as some think.
Look up the African tiger fish. It looks like a striped bass with a mouth full of sharp bayonets. They're strongly suspected of having caused the disappearance of some fishermen who fell out of their canoes where schools of tiger fish were.
One of my favorites is the Payara. The lower jaw teeth are so long that with the mouth closed, the fangs protrude through the nostrils! This is the one that Wade calls the Vampire Fish on his show.
I've seen a number of mounted examples, and the sight is sobering. The long teeth are used to puncture the swim bladder on its victim fish.
