Description
The elephantnose fish is a dark elephantfish of the family Mormyridae (elephantfishes) reaching about 35 cm. Characteristic is the long, mobile, finger-like appendage on the lower chin - the 'trunk' - with which the fish probes the bottom for prey. Like other elephantfishes it generates a weak electric field with an organ in the tail base, with which it navigates in turbid water, detects prey and communicates with conspecifics. To process these electric signals it has, in proportion, one of the largest brains among fish. The species comes from West and Central Africa and lives in slow, turbid water of rivers, creeks and swamps. At night it searches for insect larvae and small invertebrates. It is popular in the aquarium hobby.
