Eel-like lampreys are an invasive species found in the Great Lakes, and one that can have a very negative impact on native fish. The lampreys attach themselves to host fish (often commercially valuable species) and extract blood and nutrients from them weakening and often killing the fish.
A student at the University of Windsor has been studying how lampreys detect and process scents. That information could lead to better and more effective traps for the lamprey, which would in turn allow officials to remove them from the lakes and reduce the threat to native fish.
From Metro News:
“Green’s study is an extension of his academic supervisor Professor Barbara Zielinski’s work, which found a pathway that links the sense of smell to the locomotive circuit in lampreys’ brains. That circuit, the medial region in the olfactory bulb, allows them to smell something and move towards or away from that odour.”
