Don't be such girls!
Trout have tiny weeny teeth, no sharper than sandpaper! Try catching a tope or a conger eel. Those feckers will take a couple of your fingers as soon as look at you.

For a closer comparison though, try the common LSD (Leser spotted dogfish). They really do have skin like heavy sandpaper and they wriggle and squirm while you're trying to unhook them. When I first caught one, the mates I was with shared an interesting tale of some bloke who was fishing topless one sunny day and lost a nipple by not holding an LSD properly.

As a little aside, (sea) Bass gill covers are sharp as blades and will easily do enough damage to stop you fishing for a while.
