Elephant-nose fish need to twist, pace and shimmy to accurately “see” the shapes of objects when interpreting wobbles in electric fields.

Peters’s elephant-nose fish (Gnathonemus petersii) is native to the rivers of west and central Africa. It and its close relatives are “weakly electric” fish that can produce a small electric discharge too feeble to stun prey. But sensors in their skin can use the resulting electric field around their bodies to detect prey and underwater obstacles. …
