I've never seen a live one, but when I was a kid my back yard was littered with 
their corpses as they'd die after spawning and would catch on rocks and sticks 
in the river shallows.

Fields of brook lampreys. That must have been a sight. I never saw them and
the 20 or so lampreys in the counting tank were catched by fishermen with
some kind of electric stunning device to catch all the fish.
Sad to realize what has gone in a few decades.

Re: PESO: European brook lamprey

[mike wilson]

Lampreys are fascinating organisms.  Apart from being (afaik) the only 
four-eyed vertebrate, their body chemistry provides rich hunting grounds for 
pharmaceutics.  Some are anadromous, some are not; some have a parasitic phase 
of their life cycle, some do not.

As a child, I remember seeing "fields" of brook lampreys in streams, only the 
upper parts of their bodies out of the gravel as they hunted passing 
invertebrates in the current.

Used as a meat substitute here during Lent, due to the non-fishy taste of the 
flesh, they were usually eaten in pies.

If I remember correctly, there was a Roman governor who enjoyed executing 
people by having them thrown into his lamprey pool.
