Peters’ Elephantnose Fish (Gnathonemus petersii)
Elephantnose fish originate from the rivers of West and Central Africa, where they live in muddy, slow moving waters. They have a trunk-like protrusion from the head, which gives them their name.
The ‘trunk’ is actually an extension of the mouth, and is covered in electroreceptors that the fish uses in finding prey, communication and navigation. Specially adapted muscle tissue near its tail produces a weak electric field.
The electroreceptors, which are also distributed along its body can detect small disturbances in the electric field, such as those caused by moving prey in the substrate. It also allows the fish to navigate in complete darkness.
