The Elephantnose Fish is a freshwater fish of Africa named for the long, sensitive extension of his mouth, which somewhat resembles an elephant's trunk. This organ is covered in electrosensors, which he uses to locate food as his eyesight is rather poor, although he can see resonably well in low light levels. He generates a weak electric field via muscle contractions to sense his surroundings. His brain is the largest in proportion to body weight of any vertebrate. Fairly common in the pet trade, he mixes well with other fish but can be territorial with others of his kind.
