Peters’ Elephantnose Fish (Gnathonemus petersii)

The elephantnose fish is a freshwater fish native to the rivers of West and Central Africa. Their trunk-like protrusion is an extension of the mouth that is covered with sensitive electroreceptors. The fish is able to use these receptors, along with a weak electrical field that it generates through muscular contractions, to find hidden prey and navigate in low visibility conditions.
