An electric eel can generate enough current to stun its prey. Johns Hopkins University neuroethologist Eric Fortune traveled to Ecuador to study electric knifefish in their native habitat. Back at Johns Hopkins University, research collaborator mechanical engineer Noah Cowan and the rest of the team use Fortune's field data to help with their observations and experiments in the lab. With support from the National Science Foundation, they are studying the knifefish to learn more about how the brains of animals work to control their behavior.
