Fans of Roderick on the Line may recognize these as living metaphors for modern marketing offers. But they’re invading the Great Lakes (literally) where they grow to adulthood and (literally) drain the blood of native fish.
On the other hand (not literally), aww! Cute baby animals!
According to the US Geological Survey, where I found this image, the slower they grow, they more likely these lampreys are to be male. No word on how that’ll help control their population….
