The Northern Hogsucker is found in clear, fast streams in the Great Lakes, Hudson Bay and Mississippi River basins. It uses its long snout to dig around in the sediments, turning over rocks in search of small aquatic insects or snails. Once it finds something it will – quite literally – suck it up. It’s basically the vacuum cleaner of the freshwater world. They can grow to up to 2 ft in length and live for up to 11 years.
