"Am I to just take your word on that? LOL"

Yes.

It's a well adapted, parasite that feeds on blood. As long as there are other creatures with blood (and no hands with which to remove it), the lamprey will eat. Any population of lampreys that were acted on by significant forces may well have evolved into something else but the basic design of the lamprey and it's niche is well protected. So long as creatures with blood live in the sea.

In contrast to the pitifully few lampray species, mosquitos, also blood suckers, have proliferated as few other animals ever have.

They are everywhere!

Admit it, the lampray is the perfect animal ~ untouched by the forces of Natural Selection ~ beyond mere statistics.

"So long as creatures with blood live in the sea."

I'm sorry, but you should have said, so long as creatures exist with skin, or scales, or something else, have existed which the lamprey's blood sucking equipment can access, have lived in the sea. Any type of statement like this which proposes to cover 360,000,000 years of evolution, is quite suspicious to me.
