Lake Chub (Couesius plumbeus)

Some just say it's a fish eat fish world, but others actually take it to heart. The lake chub is reportedly one of those with this cannibalistic tendency, chowing down on the occasional fish when not snacking on insects, or algae. The scary side of it? In every other aspect, the lake chub seems completely and totally normal, almost too normal... It's found throughout northern North America, moves to shallow waters when spawning season comes around, and turns out to be a resilient species most anywhere it is found. In addition, the shady fish has one of the most precise circadian rhythms of any studied fish, which may or may not be a tad eerie. What turned the lake chub into a fish with a reputation erring on the vulturistic side is a mystery.
