My understanding is that they are jawless fish -- fish are bony, cartilaginous or
jawless. The Pacific Lamprey and River Lamprey appear in all my fish books, and I
really trust the Probably More Than You Want to Know About the Fishes of the
Pacific Coast book by Milton Love (see his Lovelab web site). They are blood
suckers, but start out in streams (5 years or so), go out to the ocean, migrate
back up to spawn and die - sounds like a fish to me! katrina
