They look like leaches, nasty little blood suckers. That make great walleye bait.
Think about a regular American Eel, only instead of a mouth like one of those, lampreys have a round suction cup in their face, with rows of rasping teeth. They cling onto larger fish and suck out the blood. Sort of like a vampire. LOL! I've seen them as large as 3 - 4 pounds. They migrate from the sea however, so their introduction normally requires a river dumping into the ocean.
